MorphOS TinyGL update 2023-08-14
================================
This is the ninth public MorphOS TinyGL update resulting from the TinyGL
bounty at https://tinygl.molsen.co.za/.

The main changes in this update are:
- Addition of a driver for Evergreen and Northern Islands based Radeons.

See later in this file for a more detailed list of changes.

Which Radeon family does my Radeon belong to?
---------------------------------------------
Later in this readme there is information to help you identify which Radeon
family your graphics card belongs to. This update covers the R200, R300, R400
and R500, Evergreen and Northern Islands families of Radeon chips. Some
features are currently only available for some Radeon models. Find your
graphics card in the list below to see if a particular feature or example
applies to your system.

Examples
--------
This update contains three examples that have been used to test some of the
new functionality introduced in this TinyGL update.

The "Cube Map Skybox" example demonstrates the use of OpenGL cube maps to
render what's known as a skybox, a static background often used in games and
applications to give the appearance of a detailed background and sky with
minimal hardware processing requirements.

The "Bump2D" example demonstrates the use of fragment programs to create
effects not possible with the fixed function OpenGL pipeline. In this case it
creates a classic bump mapping effect, giving the illusion of detailed lighting
being applied to a surface. Parts of the surface - the metallic parts - also
have extra lighting applied to them, to give the illusion of them being shiny.
In this update, this example only works on Radeon graphics cards in the R300
and R400 families. Future updates will make this example work on all supported
Radeon graphics cards. Many thanks to Andre Siegel for supplying the artwork
for this example!

The "Shader Test" example demonstrates the use of OpenGL vertex and fragment
shaders to create effects that would not possible with the fixed function
OpenGL pipeline. This example uses a vertex shader to animate the rendered
object and a fragment shader to create custom lighting effects as well as
conditional discarding of output fragments, creating the illusion that the
rendered model is more detailed than it actually is.

"ShaderBoy" is an application that allows you to test and play around with
shaders. It has several different presets and allows you to edit vertex and
fragment shaders, with a live display of the result of those shaders. It also
allows you to edit various OpenGL states including textures and lighting.
"ShaderBoy" was developed by Antoine "Tcheko" Dubourg and I'd like to extend
a big thank you to him for developing it and allowing me to include it in the
TinyGL update!

SDK
---
The SDK directory contains updates to the MorphOS SDK and source code for the
examples included in this update. The SDK update has to be installed manually
by copying the contents of the SDK/GG directory to your SDK GG directory. You
can copy the files by executing the following commands from a shell, with the
current directory being the TinyGL update directory:

delete gg:ppc-morphos/lib/libGL.a
copy SDK/GG/#? gg: all quiet clone

Please note that there's no check to make sure that your SDK is not newer than
the files contained in this update. Only install the SDK files if your
currently installed SDK is older than this TinyGL update.

Also please note that any software compiled with the updated SDK will require
tinygl.library version 53.0 or higher, and thus either MorphOS 3.18 or MorphOS
3.17 + this separate TinyGL update. If you manually open tinygl.library, you
_must_ update your code to request version 53!

To build the examples, go to the SDK/Examples directory and run the following
command:

make

Changes from 2022-12-27 to 2023-08-14
-------------------------------------
freeglut.library:
- Library version is now 53.1
- Now zeroes out the application's OpenGL context pointer when the application closes a GLUT window that was the currently active GLUT window for OpenGL rendering. Prevents accidentally using a deleted OpenGL context.

tinygl.library:
- Library version is now 53.8
- No longer attempts to update fixed-function state in the driver when fixed-function-as-shaders is active, as the latter replaces the former.
- All OpenGL 2.1 states that are settable glPixelStoref() and glPixelStorei() now have correct default values and can be queried with the relevant glGet#?() functions. Please note that even though correct state is being kept now, not all functionality is fully implemented.
- 1D textures are now natively supported by drivers instead of being emulated as 2D textures by tinygl.library.
- Fixed a bug where a texture unit's base texture format was not updated when enabling or disabling 1D, 2D or cubemap texturing for that unit, which could cause the wrong texture function to be applied to that unit.
- When an application causes an OpenGL error to get generated, tinygl.library now generates debug output to notify developers of this error. For some errors, an explanation of why the error was generated is also included.

r200.library:
- Library version is now 53.5
- Added driver-native support for 1D textures.

r300.library:
- Library version is now 53.11
- Added driver-native support for 1D textures.
- Fixed a bug where in certain very rare cases, uniform values updated by an application would not immediately take effect in hardware.
- Optimised shader state handling, resulting in faster execution of applications that frequently switch between different shaders.

r600.library:
- New driver that adds support for Evergreen and Northern Islands based Radeons. Please note that this driver is still work-in-progress and that misrendering and even crashes should be expected.

SDK:
- Updated libGL.a and libglut.a to better coexist. Fixes a problem where GLUT applications could crash depending on the order in which those two libraries were linked into the appliction.

Changes from 2022-12-21 to 2022-12-27
-------------------------------------
tinygl.library:
- Library version is now 53.7
- Fixed multiple issues with GL_RGB5_A1 textures.
- Fixed a problem with ARB fragment programs that caused such programs that used non-consecutive texture image units to fail. For example a program that used texture unit 0 and texture unit 2, but not texture unit 1 would misrender.
- Fixed a problem with mipmapped cubemaps where such textures would get treated as 2D textures rather than cube map textures. This problem only affected textures which are mipmap complete.

r300.library:
- Library version is now 53.10.
- Added support for GL_RGB5_A1 textures.

Changes from 2022-12-16 to 2022-12-21
-------------------------------------
tinygl.library:
- Library version is now 53.6
- Fixed-function-as-shaders: Fixed the the GL_BLEND texture environment function for textures with a base format of GL_RGB.
- Fixed-function-as-shaders: Fixed glColorMaterial() with mode set to either GL_AMBIENT or GL_DIFFUSE.
- Fixed-function-as-shaders: Fixed alpha channel output from the vertex shader when GL_LIGHTING is enabled.
- Fixed crashes and misrenders when resizing a window mode context while an ARB or GLSL program is active.

SDK:
- Added function pointer typedefs for every OpenGL function.

Changes from 2022-10-19 to 2022-12-16
-------------------------------------
tinygl.library:
- Library version is now 53.5
- Implemented the fixed function OpenGL vertex and fragment pipeline as dynamically generated shaders. This implementation is used on graphics cards that support shaders instead of the previous limited fixed function support in hardware/drivers.
- Now supports setting and retrieving all OpenGL 2.1 glEnable() and glDisable() states, although no actualy functionality has been added for most of the new states yet.
- Added support for GL_COLOR_SUM.
- Fixed a problem where using glBufferData() to overwrite the contents of an existing vertex buffer object could lead to the new data not being used by the driver right away.
- glGetBufferParameteriv() now supports querying the following attributes: GL_BUFFER_ACCESS, GL_BUFFER_MAPPED and GL_BUFFER_USAGE.
- glTexGen#?() now reject setting GL_TEXTURE_GEN_MODE to GL_SPHERE_MAP for the GL_R and GL_Q coordinates, and setting GL_TEXTURE_GEN_MODE to GL_REFLECTION_MAP for the GL_Q coordinate.
- When using TinyGL to render directly to a window, and that window is being resized, TinyGL will no longer overwrite the window borders.
- Several other problems related to using TinyGL to render directly to a window, that could cause TinyGL to misbehave and misrender, have been fixed.
- The ARB program parser now correctly parses and compiles "state.material.X" operands, and correctly handles accesses to "state.light.X" and "state.lightmodel.X".
- ARB programs that access transposed state matrices now work correctly.
- Setting and getting GL_TEXTURE_GEN_Q now works correctly.
- In ARB programs, several state variables (accessed via 'state.' in the program source code) were not automatically updated in hardware when the OpenGL state changed. This has now been fixed.
- Revamped how TinyGL keeps track of what vertex data is required to complete a draw call. Previously TinyGL could in some cases supply either not enough data, causing misrendering, or too much data, causing performance degradation.
- When using immediate mode rendering (via glBegin()), TinyGL now keeps all 4 components of the texture coordinates passed and not just the first two. This makes for example cube maps and texture matrices work when using with immediate mode.
- Added support for setting GL_LIGHT_MODEL_COLOR_CONTROL via glLightModel#?().
- Added support for getting the following states via glGet#?():
o GL_CURRENT_SECONDARY_COLOR
o GL_INDEX_MODE
o GL_LIGHT_MODEL_COLOR_CONTROL
o GL_RGBA_MODE
o GL_SECONDARY_COLOR_ARRAY_POINTER
- The initial immediate mode normal value when creating a new context has been fixed to correspond to the value required by OpenGL.
- Added support for supplying secondary colours to OpenGL via glSecondaryColor#?().
- Deleting a vertex buffer object that was currently bound to the normal array would previously keep a stale pointer to the delete vertex buffer object in the vertex array state, potentially leading to TinyGL trying to use the already deleted vertex buffer object.
- If the driver fails to compile an ARB program, the driver's error message is now passed on to the OpenGL application, rather than just returning a generic error message and discarding the driver error message.
- Using glBitmap() while a program/shader or a cubemap texture is active no longer fails.
- The glWindowPos#?() set of functions have been fixed to correctly interpret the y coordinate is having its origin at the bottom of the screen rather than the top of the screen. This primarily caused some OpenGL example code to render status text at the bottom of the display instead of the top, or vice versa.
o Please note that to preserve compatibility with existing software that expects the wrong behaviour, the standards compliant behaviour is only activated for software that calls tglEnableNewExtensions().
- TinyGL's handling of the 'default' textures for each target (texture ID 0) was broken and didn't take into account the different texture target types (GL_TEXTURE_2D, GL_TEXTURE_CUBE_MAP, etc). This caused misrendering with mostly OpenGL example apps that reused the default OpenGL texture ID for rendering cube maps, instead of allocating a new texture for it.
- The default state for OpenGL lights is now initialised correctly when creating a new context. Programs that use the default light position and never sets a position of their own now work correctly.
- The following functions now have proper OpenGL error reporting:
o glBindBuffer()
o glBufferData()
o glBufferSubData()
o glDeleteBuffers()
o glDisableClientState()
o glEnableClientState()
o glGetBufferParameteriv
o glIsBuffer()
o glLightf()
o glLightfv()
o glLighti()
o glLightiv()
o glLightModeli()
o glLightModeliv()
o glLightModelf()
o glLightModelfv()
- New OpenGL extensions advertised:
o GL_EXT_secondary_color

r200.library:
- Library version is now 53.4.
- Added support client programs directly supplying the secondary OpenGL colour.

r300.library:
- Library version is now 53.9.
- Added support client programs directly supplying the secondary OpenGL colour.
- Added support for several previously unsupported opcodes in the vertex program compiler and in the fragment program compilers for both R300/R400 and R500.
- Fixed a bug that would lead to a Radeon hardware crash when trying to use a vertex program that used no constant data at all.
- Fixed a bug where using a kill/discard instruction in a fragment program after sampling a texture could lead to program compilation failing.
- Fixed a bug that would in certain cases lead to misrendering when using more than one set of texture coordinates.
- Fixed a bug that could cause wrong texture rendering when switching between using programs/shaders and fixed function rendering.

freeglut.library:
- New port of FreeGLUT version 3.4.0 to MorphOS. This supercedes TinyGL's built-in GLUT support, is a lot more feature complete and makes it easier to port GLUT OpenGL examples to MorphOS.

SDK:
- Includes have been reworked a bit to be more MorphOS-like. clib/tinygl_protos.h is now a proper clib include that contains just the prototypes of tinygl.library's public functions.
- the includes now define GL_VERSION_x_y, with x and y corresponding to the OpenGL versions supported by the includes.
- For each OpenGL extension supported, the includes now define a preprocessor macro with the same name as the OpenGL extension, e.g. GL_ARB_vertex_buffer_object.
- Contains includes and link library for freeglut.library.

- Added vertex and fragment shader support for R500.
- Added support for the exp2() and log2() functions in vertex shaders.
- Fixed an off-by-one bug that caused the Radeon hardware to execute one more instruction than was actually contained in the vertex program, causing unpredictable outcome.
- Fixed a bug that could cause vertex shaders using a large amount of temporary registers to misbehave.
- Fixed an oversight in the fragment program compiler that caused fragment programs on R300/R400 to sometimes erroneously consider a fragment kill instruction to start a new fragment program stage, making some fragment programs fail to compile where they should have worked.
- Added a simple optimisation to the R300/R400 fragment program compiler to try the number of fragment program stages consumed.
- Fixed a problem that could make certain conditional comparisons in vertex shaders to fail to compile.
- Added an optimisation pass to reduce the number of temporary registers used. Currently only enabled for vertex programs and R500 fragment programs, with R300 fragment programs still to come.
- Fixed the reading of gl_FragCoord in fragment shaders where a vertex shader is also present.

Changes from 2022-09-04 to 2022-09-08
-------------------------------------
tinygl.library:
- Library version is now 53.2.
- Reading gl_ModelViewProjectionMatrix in a shader now works correctly.
- Shaders now work correctly after window resize.
- Similarly fixed a corner case issue with textures after window resize.
- Fixed a bug making program objects without both a vertex and a fragment shader present fail.

r300.library:
- Library version is now 53.6.
- Now supports shaders that read back from output registers.
- Now supports shaders which use write masks in combination with texture instructions.
- Fixed the fragment shader compiler to ignore source register swizzles for unused source register components in texture instructions.
- Optimised the swizzle emulation of the fragment shader compiler, resulting in smaller and faster compiled shaders.

Changes from 2022-08-05 to 2022-09-04
-------------------------------------
tinygl.library:
- Library version is now 53.1.
- Added support for OpenGL shaders.

- The ARB program parser now respects driver limits when parsing ARB programs.
- Increased the number of supported texture units from 4 to 8.

- Cleaned up the OpenGL extensions advertised by TinyGL:
o GL_EXT_texture_compression_s3tc was advertised with the wrong name, EXT_texture_compression_s3tc
o The following non-existing extensions are no longer advertised:
* GL_ARB_color_table
* GL_ARB_compiled_vertex_array
* GL_ARB_draw_range_elements
* GL_EXT_color_table
o The following extensions do exist, but are not supported, and thus no longer advertised:

- Every OpenGL 2.1 function now exists in the tinygl.library base. Note that this doesn't mean that TinyGL supports all of OpenGL 2.1's functionality yet, just that the functions exists.
- Every OpenGL 2.1 enable/disable state is now recognised by tinygl.library, and can have their set value retrieved, although not all of them have their underlying functionality implemented.
- Added support for cube mapping. (extensions: GL_ARB_texture_cube_map, GL_EXT_texture_cube_map)
- Added support for OpenGL ARB programs. (extensions: GL_ARB_fragment_program, GL_ARB_vertex_program)
- Added support for OpenGL shaders.
- Added support for GL_COLOR_SUM.
- Implemented the fixed function OpenGL vertex and fragment pipeline as dynamically generated shaders. This implementation is used on graphics cards that support shaders instead of the previous limited fixed function support in hardware/drivers.
- Many OpenGL functions that previously only had some variants of otherwise supported functions available now support all variants. These are functions whose names typically end with a single digit (1, 2, 3 or 4) followed by 1 or two characters to indicate argument type (b, d, f, i, s, ub, ui, us) and then optionally a v, for example glColor3ub(). These functions are:

- A function to obtain OpenGL function pointers at runtime, tglGetProcAddress(), has been added.
- Fixed the default settings for vertex attrib arrays.
- Fixed several bugs in the implementation of vertex buffer objects and made the implementation more complete.

- Added support client programs directly supplying the secondary OpenGL colour.
- Added support for cube maps.
- Added support for GL_TEXTURE_WRAP_R.

- Fixed a problem that in certain situations could cause R500-based Radeons to misrender when _not_ using fragment shaders/programs.

freeglut.library:
- New port of FreeGLUT version 3.4.0 to MorphOS. This supercedes TinyGL's built-in GLUT support, is a lot more feature complete and makes it easier to port GLUT OpenGL examples to MorphOS.

OpenGL test suite:
- Added texture combiner tests to my OpenGL test suite. All drivers and hardware combinations now pass all tests.

SDK:
- Please note that any software compiled with the updated SDK will require tinygl.library version 53.0 or higher, and thus either MorphOS 3.18 or MorphOS 3.17 + this separate TinyGL update. If you manually open tinygl.library, you _must_ update your code to request version 53!
- TinyGL's automatic libopen function now requires at least version 53 of tinygl.library.
- TinyGL's link library now comes in both regular and baserel flavours.
- Newly supported OpenGL extensions that introduce new functions to OpenGL are disabled by default. To enable the new extensions, call tglEnableNewExtensions(0). The passed argument _must_ be zero. If you call tglEnableNewExtensions(), then you _must_ use tglGetProcAddress() to obtain pointers to OpenGL functions present in OpenGL extensions. You _must not_ use a custom function for this purpose.
- Includes have been reworked a bit to be more MorphOS-like. clib/tinygl_protos.h is now a proper clib include that contains just the prototypes of tinygl.library's public functions.
- the includes now define GL_VERSION_x_y, with x and y corresponding to the OpenGL versions supported by the includes.
- For each OpenGL extension supported, the includes now define a preprocessor macro with the same name as the OpenGL extension, e.g. GL_ARB_vertex_buffer_object.
- Includes have been updated to fully support OpenGL 2.1, plus the following extensions:
o GL_ARB_color_buffer_float
o GL_ARB_depth_texture
o GL_ARB_draw_buffers
o GL_ARB_fragment_program
o GL_ARB_fragment_program_shadow
