| OpenGL ES Extension ### |
| |
| Dependencies |
| |
| OpenGL ES 3.0 is required. |
| |
| The extension is written against the OpenGL ES 3.2 specification. |
| |
| Overview |
| |
| This extension allows defined results when reading from a depth |
| texture that is bound as a read-only depth buffer. |
| |
| IP Status |
| |
| No known IP claims. |
| |
| New Procedures and Functions |
| |
| None |

| Additions to Chapter 8 of the OpenGL ES 3.2 Specification (Textures and |
| Samplers) |
| |
| Added to the list of conditions in 8.14.2.1 (Rendering Feedback Loops): |
| |
| "The texture is not a depth/stencil texture, or the value of |
| DEPTH_WRITEMASK is not FALSE." |
| |
| Additions to Chapter 9 of the OpenGL ES 3.1 Specification (Framebuffers and |
| Framebuffer Objects) |
| |
| Removed from the end of section in 9.3.1 (Rendering Feedback Loops): |
| |
| "Also note that even if writing to a given texture is disabled (e.g. via the color, |
| depth, or stencil writemasks) during rendering, a feedback loop will still occur." |
