Version 1.2 - 2021/04/17

General:

  • updated GL4ES Documentation
  • updated all libs, see below for the changelog.
  • everything compiled with GCC 10.3.0

GL4ES (updated till commit done Apr 15, 2021):

  • Improve glGetError() handling

  • Set default GL version to 2.1 (instead of 2.0) for GLES2.0 backend

  • GLSL version 1.2 is default now, instead of GLSL 1.1

  • Added ARB_vertex_program and ARB_fragment_program, which is major work by itself and some of the notable changes are:

    • Added support for Program Matrix from ARB_vertex_program extension
    • include support for GradARB variant for texture2D and textureCube built-in functions
    • Added ARL and relative addressing support
    • Added the ARB vertex shader attribute vertex.attrib
    • Added the ARB parameter state.matrix.texture
    • Added support for ARB_fog_linear
    • Added support of ARB_precision_hint_nicest option
    • Added 'OPTION ARB_position_invariant' to ARB_vertex_program
    • Added sign support for single-value params
    • Added support for direct constant in ARB language

  • Improved FPE with more compatibility fixes

  • Improved Handling of DXTc textures + added some support for DXTc with sRGB textures

  • Improve handling of partial mipmapped textures

  • Added support for Texture LOD access in Fragment Shaders

  • Increased maximum Texture Unit support to 16 (from 8)

  • Added support for a program without Vertex Shader

  • Some fixes for programs that switch GLX Context frequently.

  • Fixes and improvements in fpe_shaders (less array access)

  • Added support for Clipping Plane in custom shaders (help OpenMW water reflection)

  • Added support for multiple FBO attachment (if hardware support it)

  • More optimization on real VBO handling

  • Proper handling of gl_ClipVertex

  • AmigaOS4 specific changes (by ptitSeb and Daniel):

    • Fix: typo in pixel.c, pixel.g was not set
    • Cleaning up Logging
    • Introduced define GL4ES_COMPILE_FOR_USE_IN_SHARED_LIB so gl4es can be used inside of minigl.library (minigl4gl4es) amiga shared library.
    • Additionl extensions GL_MGL_packed_pixels (old Amiga flavour of GL_EXT_packed_pixels) and GL_EXT_compiled_vertex_arrays (note the s at the end, a common typo...)
    • build info can be disabled by silence-define
    • FPS drawing in its own function so that it can be called from outside in case aglSwapBuffers is not called by the client.
    • Improved env var handling.
    • Added a BigEndian only fastpath for GL_INT_8_8_8_8_REV <-> GL_UNSIGNED_BYTE conversion (not more slow-route)
    • Fixed some conversion involving GL_INT_8_8_8_8(_REV) and GL_BGRA that used 2 passes where 1 would be enough
    • Added a few more AmigaOS4 specifics texture format handling, so no conversion needs it at all. Thanks to Daniel for ogles2.library v3.1 where he added new, aos4 only, formats.
      GL_AOS4_texture_format_RGB332
      GL_AOS4_texture_format_RGB332REV
      GL_AOS4_texture_format_RGBA1555REV
      GL_AOS4_texture_format_RGBA8888
      GL_AOS4_texture_format_RGBA8888REV

  • And a gazillion of improvements, fixes, dealing with regressions and new features. An actual changelog is MUCH bigger, and there is only a summary. For the full list go to https://github.com/ptitSeb/gl4es/commits/master
