See docs/README.directfb -for details. - - - -Vertex/Fragment Program PRINT Instruction ------------------------------------------ - -The GL_NV_vertex_program and GL_NV_fragment_program languages have been -extended with a PRINT instruction. - - - -glDeleteTextures(), glDeletePrograms() and glDeleteBuffers() Changed --------------------------------------------------------------------- - -To match the behaviour of other OpenGL implementations, glDeleteTextures, -glDeletePrograms and glDeleteBuffers have been modified so that: - - * The named texture/program/buffer ID is immediately freed for re-use. - - * The actual texture object, program or buffers isn't really deleted until - it is no longer bound in any rendering context (the reference count - is zero). - -Previously, the texture/program/buffer ID wasn't freed until the object -was really deleted. - -Note that textures, programs and buffers can be shared by several rendering -contexts so they can't be deleted until they're unbound in _all_ contexts. - - - -GL_EXT_framebuffer_object changes ---------------------------------- - -Implementing this extension involved changing a lot of code (for the better). - -The gl_framebuffer object now a collection of gl_renderbuffer objects. -Renderbuffers may store colors, stencil indices, or depth values. The -gl_framebuffer and gl_renderbuffer types are object-oriented in design. - -All the old RGB, color index, stencil and depth-related span functions for -reading/writing pixels from/to buffers has changed. Now, all pixels are -read/written through a set of common renderbuffer functions (methods). - -Most device drivers have been updated for these changes, but some haven't. - - - -To Do (someday) items ---------------------- - Switch to freeglut - Increase MAX_DRAWBUFFERS - driver hooks for BeginQuery/EndQuery - - - -Miscellaneous -------------- - -The main/get.c file is now generated with a Python script (get_gen.py). - - - -Driver Status ----------------------- --------------------- -XMesa (Xlib) implements OpenGL 1.5 -OSMesa (off-screen) implements OpenGL 1.5 -Glide (3dfx Voodoo1/2) implements OpenGL 1.3 -SVGA implements OpenGL 1.3 -Wind River UGL implements OpenGL 1.3 -Windows/Win32 implements OpenGL 1.5 -DJGPP implements OpenGL 1.5 -GGI implements OpenGL 1.3 -BeOS implements OpenGL 1.5 -Allegro needs updating -D3D needs updating - - ----------------------------------------------------------------------- |
