Program-specific Uniform Assignment Tests
|
||
|
|
|
||
|
|
Tests:
|
||
|
|
+ dEQP-GLES31.functional.program_uniform.*
|
||
|
|
|
||
|
|
Includes:
|
||
|
|
+ Assigning uniform values for a single program with glProgramUniform*
|
||
|
|
+ Various uniform types
|
||
|
|
- Most basic types
|
||
|
|
- Structs and arrays, including nested
|
||
|
|
+ Both by-pointer and by-value variants of functions tested
|
||
|
|
+ Uniforms used in vertex shader, fragment shader, or both
|
||
|
|
+ Verify by glGetUniform* or rendering
|

|
|
|
||
|
|
Excludes:
|
||
|
|
+ Assigning uniforms to multiple programs
|
||
|
|
+ Sampler types other than 2d and cube

+ Negative tests

Description:
|
||
|
|
|
||
|
|
The glProgramUniform* tests use the alternative uniform assignment API (in
|
||
|
|
contrast to the glUniform* functions) for assigning uniform values to a
|
||
|
|
different program than the currently active one.
|
||
|
|
|
||
|
|
Various combinations of uniforms are tested: single basic-type uniforms, arrays,
|
||
|
|
structs, and nested structures with arrays. Each active uniform is assigned
|
||
|
|
a value using an appropriate glProgramUniform* function, either the pointer
|
||
|
|
variant or the value variant (if possible; for instance, matrices can only be
|
||
|
|
assigned using the pointer variant). Arrays with basic element type can have
|
||
|
|
their first element identified using either just the array's name or that
|
||
|
|
appended with "[0]"; both methods are tested.
|
||
|
|
|
||
|
|
To verify that the correct uniform values were assigned, either the uniform
|
||
|
|
values are queried with glGetUniform* or the shaders are rendered with; the
|
||
|
|
shaders are constructed such that the result should be an all-green quad if
|
||
|
|
the uniforms have correct values, and all-black otherwise.
|
||
|
|
|
||
|
|
At the beginning of each test case, a dummy program is created and made active
|
||
|
|
with glUseProgram; otherwise, the glProgramUniform* calls would behave just as
|
||
|
|
the corresponding glUniform* calls.
