Vertex Attribute Binding Tests
|
||
|
|
|
||
|
|
Tests:
|
||
|
|
+ dEQP-GLES31.functional.vertex_attribute_binding.*
|
||
|
|
+ dEQP-GLES31.functional.state_query.vertex_attribute_binding.*
|
||
|
|
+ dEQP-GLES31.stress.vertex_attribute_binding.*
|
||
|
|
|
||
|
|
Includes:
|
||
|
|
+ Vertex attribute binding state setting and queries
|
||
|
|
+ Drawing with all attributes sourced from a single buffer
|
||
|
|
- Single and multiple attributes, multiple attributes sharing
|
||
|
|
components.
|
||
|
|
- Non-zero buffer offset
|
||
|
|
- Sourcing elements at an aligned location from a buffer with
|
||
|
|
a combination of non-aligned buffer offset and non-aligned
|
||
|
|
vertex attribute start offset.
|
||
|
|
+ Drawing with all attributes sourced from different binding points
|
||
|
|
- Basic drawing
|
||
|
|
- Binding point stride set to zero
|
||
|
|
- Binding point instance divisor
|
||
|
|
- Binding same buffer object to multiple binding points
|
||
|
|
+ Mixing vertex attribute binding and vertex attribute pointer APIs
|
||
|
|
- Different APIs for different vertex attributes
|
||
|
|
- Use vertex attribute binding API to change state set with vertex
|
||
|
|
attribute pointer API
|
||
|
|
+ Negative tests
|
||
|
|
- Use with default VAO
|
||
|
|
- BindVertexBuffer for non-gen'd buffer name
|
||
|
|
- Invalid values
|
||
|
|
+ Stress tests
|
||
|
|
- Sourcing elements over buffer bounds
|
||
|
|
- Sourcing elements at non-aligned locations
|
||
|
|
|
||
|
|
Excludes:
|
||
|
|
+ Use of all vertex attribute binding points
|
||
|
|
+ Sourcing elements from a buffer with a large stride/offset
|
||
|
|
+ Buffer object lifetime/validity after deleteBuffers
|
||
|

Description:
|
||
|
|
|
||
|
|
State query tests verify initial values, and state setting and
|
||
|
|
querying functions by setting random values. Modifications to
|
||
|
|
vertex attribute binding state after use of vertex attribute
|
||
|
|
pointer API is also verified.
|
||
|
|
|
||
|
|
Rendering tests set vertex attribute state using vertex attribute
|
||
|
|
binding API and issue a single draw command. Resulting image is
|
||
|
|
then verified. Mixed API rendering tests intermix both vertex
|
||
|
|
attribute binding and the vertexAttribPointer API commands to
|
||
|
|
modify the state of the same or different vertex attributes.
|
||
|
|
|
||
|
|
Stress tests source elements at invalid locations. Tests source
|
||
|
|
elements out of buffer range and at non-aligned locations using
|
||
|
|
binding point buffer offset and/or vertex attribute relative
|
||
|
|
offset.
