Trying to narrow down a list of extensions which are still relevant when using a gl3 forward compatible context.
So far my list is
[ul][li] ARB_draw_instanced[] ARB_geometry_shader4[] ARB_instanced_arrays[] ARB_texture_buffer_object[] ARB_texture_rectangle[] ATI_texture_mirror_once[] EXT_bindable_uniform[] EXT_depth_bounds_test[] EXT_direct_state_access[] EXT_texture_compression_latc[] EXT_texture_compression_s3tc[] EXT_texture_filter_anisotropic[] EXT_texture_mirror_clamp[] EXT_timer_query[] NV_copy_depth_to_color[] NV_depth_clamp[] NV_framebuffer_multisample_coverage[] NV_multisample_filter_hint[] NV_parameter_buffer_object[*] NV_texture_compression_vtc[/ul][/li]That is just based on filtering out the obviously old or moved to core extensions from the extensions list on my nv card, so I’m probably missing some from other vendors.
Basically I’m looking for extensions which:
- haven’t been added to core GL
- haven’t been replaced by something in core (combiners, asm programs, etc)
- have a reasonable chance of showing up on gl3 drivers/hardware
- aren’t something that would be obviously deprecated
- wouldn’t be better to implement by hand in a shader (some on the so far might not qualify there, didn’t read them closely)
Any suggestions for additions or removals?
