Class NVComputeShaderDerivatives


  • public final class NVComputeShaderDerivatives
    extends java.lang.Object
    This extension adds Vulkan support for the SPV_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}). The DerivativeGroupLinearNV execution mode assembles shader invocations into 2x2 groups, where each group has local invocation index values of the form 4m+{0,1,2,3}.
