| OpenGL ES Extension #352 |
| |
| Dependencies |
| |
| Either OpenGL ES 3.1 or OpenGL ES 3.0 with multisample texture support is |
| required. |
| |
| This extension is written against the OpenGL ES 3.2 specification and |
| version 3.20 ES of the OpenGL Shading Language Specification. |
| |
| This extension interacts with OES_texture_storage_multisample_2d_array |
| and OpenGL ES 3.2. |
| |
| Overview |
| |
| This extension provides GLSL built-in functions allowing shaders to query |
| the number of samples of a texture. |
| |
| New Procedures and Functions |
| |
| None. |
| |
| New Tokens |
| |
| None. |
| |
| Additions to the OpenGL ES 3.2 Specification |
| |
| None. |
| |
| Errors |
| |
| None. |
| |
| New State |
| |
| None. |
| |
| New Implementation Dependent State |
| |
| None. |
| |
| Modifications to The OpenGL ES Shading Language Specification, Version 3.20 |
| |
| Including the following line in a shader can be used to control the |
| language features described in this extension: |
| |
| #extension GL_EXT_shader_texture_samples |
| |
| A new preprocessor #define is added to the OpenGL ES Shading Language: |
| |
| #define GL_EXT_shader_texture_samples 1 |
| |
| Add to table in section 8.9.1 "Texture Query Functions" |
| |
| Syntax: |
| |
| lowp int textureSamples(gsampler2DMS sampler) |
| lowp int textureSamples(gsampler2DMSArray sampler) |
| |
| Description: |
| |
| Returns the number of samples of the texture bound to <sampler>. |
| |
| Dependencies on OES_texture_storage_multisample_2d_array and OpenGL ES 3.2 |
| |
| If neither OES_texture_storage_multisample_2d_array nor OpenGL ES 3.2 are |
| supported, ignore references to gsampler2DMSArray. |
| |
