| 1425 | Comments on renderability of configs on various GL versions. |
| 1426 | OpenGL < 3.0: |
| 1427 | no built in support for render targets. |
| 1428 | GL_EXT_framebuffer_object adds possible support for any sized format with base internal |
| 1429 | format RGB, RGBA and NV float formats we don't use. |
| 1430 | This is the following: |
| 1431 | R3_G3_B2, RGB4, RGB5, RGB8, RGB10, RGB12, RGB16, RGBA2, RGBA4, RGB5_A1, RGBA8 |
| 1432 | RGB10_A2, RGBA12,RGBA16 |
| 1433 | Though, it is hard to believe the more obscure formats such as RGBA12 would work |
| 1434 | since they aren't required by later standards and the driver can simply return |
| 1435 | FRAMEBUFFER_UNSUPPORTED for anything it doesn't allow. |
| 1436 | GL_ARB_framebuffer_object adds everything added by the EXT extension and additionally |
| 1437 | any sized internal format with a base internal format of ALPHA, LUMINANCE, |
| 1438 | LUMINANCE_ALPHA, INTENSITY, RED, and RG. |
| 1439 | This adds a lot of additional renderable sized formats, including ALPHA8. |
| 1440 | The GL_ARB_texture_rg brings in the RED and RG formats (8, 8I, 8UI, 16, 16I, 16UI, |
| 1441 | 16F, 32I, 32UI, and 32F variants). |
| 1442 | Again, the driver has an escape hatch via FRAMEBUFFER_UNSUPPORTED. |
| 1443 | |
| 1444 | For both the above extensions we limit ourselves to those that are also required by |
| 1445 | OpenGL 3.0. |
| 1446 | |
| 1447 | OpenGL 3.0: |
| 1448 | Any format with base internal format ALPHA, RED, RG, RGB or RGBA is "color-renderable" |
| 1449 | but are not required to be supported as renderable textures/renderbuffer. |
| 1450 | Required renderable color formats: |
| 1451 | - RGBA32F, RGBA32I, RGBA32UI, RGBA16, RGBA16F, RGBA16I, |
| 1452 | RGBA16UI, RGBA8, RGBA8I, RGBA8UI, SRGB8_ALPHA8, and |
| 1453 | RGB10_A2. |
| 1454 | - R11F_G11F_B10F. |
| 1455 | - RG32F, RG32I, RG32UI, RG16, RG16F, RG16I, RG16UI, RG8, RG8I, |
| 1456 | and RG8UI. |
| 1457 | - R32F, R32I, R32UI, R16F, R16I, R16UI, R16, R8, R8I, and R8UI. |
| 1458 | - ALPHA8 |
| 1459 | |
| 1460 | OpenGL 3.1, 3.2, 3.3 |
| 1461 | Same as 3.0 except ALPHA8 requires GL_ARB_compatibility/compatibility profile. |
| 1462 | OpengGL 3.3, 4.0, 4.1 |
| 1463 | Adds RGB10_A2UI. |
| 1464 | OpengGL 4.2 |
| 1465 | Adds |
| 1466 | - RGB5_A1, RGBA4 |
| 1467 | - RGB565 |
| 1468 | OpenGL 4.4 |
| 1469 | Does away with the separate list and adds a column to the sized internal color format |
| 1470 | table. However, no new formats become required color renderable. |
| 1471 | |
| 1472 | ES 2.0 |
| 1473 | color renderable: RGBA4, RGB5_A1, RGB565 |
| 1474 | GL_EXT_texture_rg adds support for R8, RG5 as a color render target |
| 1475 | GL_OES_rgb8_rgba8 adds support for RGB8 and RGBA8 |
| 1476 | GL_ARM_rgba8 adds support for RGBA8 (but not RGB8) |
| 1477 | GL_EXT_texture_format_BGRA8888 does not add renderbuffer support |
| 1478 | GL_CHROMIUM_renderbuffer_format_BGRA8888 adds BGRA8 as color-renderable |
| 1479 | GL_APPLE_texture_format_BGRA8888 does not add renderbuffer support |
| 1480 | |
| 1481 | ES 3.0 |
| 1482 | - RGBA32I, RGBA32UI, RGBA16I, RGBA16UI, RGBA8, RGBA8I, |
| 1483 | RGBA8UI, SRGB8_ALPHA8, RGB10_A2, RGB10_A2UI, RGBA4, and |
| 1484 | RGB5_A1. |
| 1485 | - RGB8 and RGB565. |
| 1486 | - RG32I, RG32UI, RG16I, RG16UI, RG8, RG8I, and RG8UI. |
| 1487 | - R32I, R32UI, R16I, R16UI, R8, R8I, and R8UI |
| 1488 | ES 3.1 |
| 1489 | Adds RGB10_A2, RGB10_A2UI, |
| 1490 | ES 3.2 |
| 1491 | Adds R16F, RG16F, RGBA16F, R32F, RG32F, RGBA32F, R11F_G11F_B10F. |
