Rasterized points, lines 40*35238bceSAndroid Build Coastguard Workerand triangles are compared to reference, and a deviation of 1 pixel in 41*35238bceSAndroid Build Coastguard Workerposition is allowed. 42*35238bceSAndroid Build Coastguard Worker 43*35238bceSAndroid Build Coastguard WorkerFill rules are tested using additive blend so that pixels on shared 44*35238bceSAndroid Build Coastguard Workertriangle edges are filled exactly once. Because exact fill rules are 45*35238bceSAndroid Build Coastguard Workernot specified, reference rasterizer uses all valid combinations of 46*35238bceSAndroid Build Coastguard WorkerLEFT, RIGHT, TOP and BOTTOM. 47*35238bceSAndroid Build Coastguard Worker 48*35238bceSAndroid Build Coastguard WorkerValue interpolation is tested for lines and triangles with 49*35238bceSAndroid Build Coastguard Workervertex-specific colors, small deviation in interpolated color is allowed. 50*35238bceSAndroid Build Coastguard Worker 51*35238bceSAndroid Build Coastguard WorkerMultisample rasterization is tested with points, lines and triangles. 52*35238bceSAndroid Build Coastguard WorkerBecause sampling pattern is unknown, deviation in produced colors is 53*35238bceSAndroid Build Coastguard Workerallowed. 54
