Each primitive is tested using a single 45 (generated) attribute array, multiple attribute arrays, instanced 46 attribute array (instance divisor > 0) and with a non-array current 47 attribute. 48 49 DrawArraysIndirect firstVertex cases draw random triangles using 50 glDrawElementIndirect with firstVertex > 0 and compare results to a 51 generated reference image. 52 53 DrawElementsIndirect index array cases draw random triangles using 54 glDrawElementIndirect with index types of unsigned byte, short and int 55 with both firstIndex = 0 and firstIndex = 1 and compare results to 56 generated reference images. 57 58 DrawElementsIndirect baseVertex cases draw random triangles with index 59 types of unsigned byte, short and int using both positive and negative 60 baseVertex values and compare results to generated reference images. 61 62 Instanced draw cases draw a grid by instancing a single tile. The result 63 is verified by simply searching for background colored (black) pixels in 64 the result image. Resulting image should not contain any background 65 colored pixels. 66 67 Negative cases test try to issue a bad indirect draw command expecting an 68 INVALID_OPERATION. Bad commands tested are commands with bad alignment, 69 commands only partially in the DRAW_INDIRECT_BUFFER buffer, and commands 70 not even partially in the DRAW_INDIRECT_BUFFER buffer. 71
