public final class AMDShaderExplicitVertexParameter extends java.lang.Object
When theVK_AMD_shader_explicit_vertex_parameter
device extension is enabled the application can pass a SPIR-V module toCreateShaderModule
that uses theSPV_AMD_shader_explicit_vertex_parameter
SPIR-V extension.When the
VK_AMD_shader_explicit_vertex_parameter
device extension is enabled theCustomInterpAMD
interpolation decoration can also be used with fragment shader inputs which indicate that the decorated inputs can only be accessed by the extended instructionInterpolateAtVertexAMD
and allows accessing the value of the inputs for individual vertices of the primitive.When the
VK_AMD_shader_explicit_vertex_parameter
device extension is enabled inputs can be also decorated with theCustomInterpAMD
interpolation decoration, including fragment shader inputs that are signed or unsigned integers, integer vectors, or any double-precision floating-point type. Inputs decorated withCustomInterpAMD
can only be accessed by the extended instructionInterpolateAtVertexAMD
and allows accessing the value of the input for individual vertices of the primitive.The
BaryCoordNoPerspAMD
decoration can be used to decorate a fragment shader input variable. This variable will contain the (I,J) pair of the barycentric coordinates corresponding to the fragment evaluated using linear interpolation at the pixel's center. The K coordinate of the barycentric coordinates can be derived given the identity I + J + K = 1.0.The
BaryCoordNoPerspCentroidAMD
decoration can be used to decorate a fragment shader input variable. This variable will contain the (I,J) pair of the barycentric coordinates corresponding to the fragment evaluated using linear interpolation at the centroid. The K coordinate of the barycentric coordinates can be derived given the identity I + J + K = 1.0.The
BaryCoordNoPerspCentroidAMD
decoration can be used to decorate a fragment shader input variable. This variable will contain the (I,J) pair of the barycentric coordinates corresponding to the fragment evaluated using linear interpolation at each covered sample. The K coordinate of the barycentric coordinates can be derived given the identity I + J + K = 1.0.The
BaryCoordPullModelAMD
decoration can be used to decorate a fragment shader input variable. This variable will contain (1/W, 1/I, 1/J) evaluated at the pixel center and can be used to calculate gradients and then interpolate I, J, and W at any desired sample location.The
BaryCoordSmoothAMD
decoration can be used to decorate a fragment shader input variable. This variable will contain the (I,J) pair of the barycentric coordinates corresponding to the fragment evaluated using perspective interpolation at the pixel's center. The K coordinate of the barycentric coordinates can be derived given the identity I + J + K = 1.0.The
BaryCoordSmoothCentroidAMD
decoration can be used to decorate a fragment shader input variable. This variable will contain the (I,J) pair of the barycentric coordinates corresponding to the fragment evaluated using perspective interpolation at the centroid. The K coordinate of the barycentric coordinates can: be derived given the identity I + J + K = 1.0.The
BaryCoordSmoothCentroidAMD
decoration can be used to decorate a fragment shader input variable. This variable will contain the (I,J) pair of the barycentric coordinates corresponding to the fragment evaluated using perspective interpolation at each covered sample. The K coordinate of the barycentric coordinates can: be derived given the identity I + J + K = 1.0.
