| OpenGL ES Extension #349 |
| |
| Dependencies |
| |
| OpenGL ES 2.0 is required. |
| OES_get_program_binary is required. |
| |
| This extension is written based on the wording of the OpenGL ES 2.0.25 |
| specification and the OES_get_program_binary extension. |
| |
| Overview |
| |
| The OES_get_program_binary extension enables applications to retrieve program |
| binaries using GetProgramBinaryOES and reload them using ProgramBinaryOES. |
| |
| The mechanism for retrieval and reloading of program binaries is vendor |
| neutral, but the binary format itself is vendor specific. |
| |
| This extension adds a token to identify program binaries that are |
| compatible with HUAWEI GPUs. |
| |
| Issues |
| |
| None |
| |
| New Procedures and Functions |
| |
| None |
| |
| New Tokens |
| |
| Accepted by the <binaryFormat> parameter of ProgramBinaryOES: |
| |
| HUAWEI_PROGRAM_BINARY 0x9771 |
| |
| Additions to Chapter 2 of the OpenGL ES 2.0 Specification (OpenGL ES Operation) |
| |
| At the end of the section 2.15.4, Program Binaries from OES_get_program_binary: |
| |
| "When querying PROGRAM_BINARY_FORMATS_OES, the format HUAWEI_PROGRAM_BINARY will be |
| present in the list of returned program binary formats and the format could be used as |
| <binaryFormat> in GetProgramBinaryOES or ProgramBinaryOES. |
| |
| An implementation may reject a HUAWEI_PROGRAM_BINARY binary if it determines |
| the program binary was produced by an incompatible or outdated version of the compiler. |
| In this case the application should fall back to providing the original OpenGL Shading |
| Language source shaders, and perhaps again retrieve the program binary for future use." |
