| 1385 | Comments on renderability of configs on various GL versions. |
| 1386 | OpenGL < 3.0: |
| 1387 | no built in support for render targets. |
| 1388 | GL_EXT_framebuffer_object adds possible support for any sized format with base internal |
| 1389 | format RGB, RGBA and NV float formats we don't use. |
| 1390 | This is the following: |
| 1391 | R3_G3_B2, RGB4, RGB5, RGB8, RGB10, RGB12, RGB16, RGBA2, RGBA4, RGB5_A1, RGBA8 |
| 1392 | RGB10_A2, RGBA12,RGBA16 |
| 1393 | Though, it is hard to believe the more obscure formats such as RGBA12 would work |
| 1394 | since they aren't required by later standards and the driver can simply return |
| 1395 | FRAMEBUFFER_UNSUPPORTED for anything it doesn't allow. |
| 1396 | GL_ARB_framebuffer_object adds everything added by the EXT extension and additionally |
| 1397 | any sized internal format with a base internal format of ALPHA, LUMINANCE, |
| 1398 | LUMINANCE_ALPHA, INTENSITY, RED, and RG. |
| 1399 | This adds a lot of additional renderable sized formats, including ALPHA8. |
| 1400 | The GL_ARB_texture_rg brings in the RED and RG formats (8, 8I, 8UI, 16, 16I, 16UI, |
| 1401 | 16F, 32I, 32UI, and 32F variants). |
| 1402 | Again, the driver has an escape hatch via FRAMEBUFFER_UNSUPPORTED. |
| 1403 | |
| 1404 | For both the above extensions we limit ourselves to those that are also required by |
| 1405 | OpenGL 3.0. |
| 1406 | |
| 1407 | OpenGL 3.0: |
| 1408 | Any format with base internal format ALPHA, RED, RG, RGB or RGBA is "color-renderable" |
| 1409 | but are not required to be supported as renderable textures/renderbuffer. |
| 1410 | Required renderable color formats: |
| 1411 | - RGBA32F, RGBA32I, RGBA32UI, RGBA16, RGBA16F, RGBA16I, |
| 1412 | RGBA16UI, RGBA8, RGBA8I, RGBA8UI, SRGB8_ALPHA8, and |
| 1413 | RGB10_A2. |
