public final class NVComputeShaderDerivatives extends java.lang.Object
This extension adds Vulkan support for theSPV_NV_compute_shader_derivatives
SPIR-V extension.The SPIR-V extension provides two new execution modes, both of which allow compute shaders to use built-ins that evaluate compute derivatives explicitly or implicitly. Derivatives will be computed via differencing over a 2x2 group of shader invocations. The
DerivativeGroupQuadsNV
execution mode assembles shader invocations into 2x2 groups, where each group has x and y coordinates of the local invocation ID of the form (2m+{0,1}, 2n+{0,1}). TheDerivativeGroupLinearNV
execution mode assembles shader invocations into 2x2 groups, where each group has local invocation index values of the form 4m+{0,1,2,3}.Examples
None.
