Description:
|
|
|
|
Primitive drawing cases draw a group of primitives with random generated
|
|
vertex attributes and compare the output to a reference image generated
|
|
by a simple reference rasterizer. Each primitive is tested using a single
|
|
(generated) attribute array, multiple attribute arrays, instanced
|
|
attribute array (instance divisor > 0) and with a non-array current
|
|
attribute.
|
|
|
|
DrawArraysIndirect firstVertex cases draw random triangles using
|
|
glDrawElementIndirect with firstVertex > 0 and compare results to a
|
|
generated reference image.
|
|
|
|
DrawElementsIndirect index array cases draw random triangles using
|
|
glDrawElementIndirect with index types of unsigned byte, short and int
|
|
with both firstIndex = 0 and firstIndex = 1 and compare results to
|
|
generated reference images.
|
|
|
|
DrawElementsIndirect baseVertex cases draw random triangles with index
|
|
types of unsigned byte, short and int using both positive and negative
|
|
baseVertex values and compare results to generated reference images.
|
|
|
|
Instanced draw cases draw a grid by instancing a single tile. The result
|
|
is verified by simply searching for background colored (black) pixels in
|
|
the result image. Resulting image should not contain any background
|
|
colored pixels.
|
|
|
|
Negative cases test try to issue a bad indirect draw command expecting an
|
|
INVALID_OPERATION. Bad commands tested are commands with bad alignment,
|
|
commands only partially in the DRAW_INDIRECT_BUFFER buffer, and commands
|
|
not even partially in the DRAW_INDIRECT_BUFFER buffer.
