Comments on renderability of configs on various GL versions.
OpenGL < 3.0:
no built in support for render targets.
GL_EXT_framebuffer_object adds possible support for any sized format with base internal
format RGB, RGBA and NV float formats we don't use.
This is the following:
R3_G3_B2, RGB4, RGB5, RGB8, RGB10, RGB12, RGB16, RGBA2, RGBA4, RGB5_A1, RGBA8
RGB10_A2, RGBA12,RGBA16
Though, it is hard to believe the more obscure formats such as RGBA12 would work
since they aren't required by later standards and the driver can simply return
FRAMEBUFFER_UNSUPPORTED for anything it doesn't allow.
GL_ARB_framebuffer_object adds everything added by the EXT extension and additionally
any sized internal format with a base internal format of ALPHA, LUMINANCE,
LUMINANCE_ALPHA, INTENSITY, RED, and RG.
This adds a lot of additional renderable sized formats, including ALPHA8.
The GL_ARB_texture_rg brings in the RED and RG formats (8, 8I, 8UI, 16, 16I, 16UI,
16F, 32I, 32UI, and 32F variants).
Again, the driver has an escape hatch via FRAMEBUFFER_UNSUPPORTED.
For both the above extensions we limit ourselves to those that are also required by
OpenGL 3.0.
OpenGL 3.0:
Any format with base internal format ALPHA, RED, RG, RGB or RGBA is "color-renderable"
but are not required to be supported as renderable textures/renderbuffer.
Required renderable color formats:
- RGBA32F, RGBA32I, RGBA32UI, RGBA16, RGBA16F, RGBA16I,
RGBA16UI, RGBA8, RGBA8I, RGBA8UI, SRGB8_ALPHA8, and
RGB10_A2.
- R11F_G11F_B10F.
- RG32F, RG32I, RG32UI, RG16, RG16F, RG16I, RG16UI, RG8, RG8I,
and RG8UI.
- R32F, R32I, R32UI, R16F, R16I, R16UI, R16, R8, R8I, and R8UI.
- ALPHA8
OpenGL 3.1, 3.2, 3.3
Same as 3.0 except ALPHA8 requires GL_ARB_compatibility/compatibility profile.
OpengGL 3.3, 4.0, 4.1
Adds RGB10_A2UI.
OpengGL 4.2
Adds
- RGB5_A1, RGBA4
- RGB565
OpenGL 4.4
Does away with the separate list and adds a column to the sized internal color format
table. However, no new formats become required color renderable.
ES 2.0
