union ExecutionMode [src]

Fields

origin_upper_leftSets origin of the framebuffer to the upper-left corner

origin_lower_leftSets origin of the framebuffer to the lower-left corner

depth_replacingIndicates that the fragment shader writes to frag_depth, replacing the fixed-function depth value.

depth_greaterIndicates that per-fragment tests may assume that any frag_depth built in-decorated value written by the shader is greater-than-or-equal to the fragment’s interpolated depth value

depth_lessIndicates that per-fragment tests may assume that any frag_depth built in-decorated value written by the shader is less-than-or-equal to the fragment’s interpolated depth value

depth_unchangedIndicates that per-fragment tests may assume that any frag_depth built in-decorated value written by the shader is the same as the fragment’s interpolated depth value

local_size: LocalSizeIndicates the workgroup size in the x, y, and z dimensions.
