C Specification
Bits which can be set in
VkClusterAccelerationStructureGeometryIndexAndGeometryFlagsNV::geometryFlags,
specifying geometry flags for cluster acceleration structure, are:
// Provided by VK_NV_cluster_acceleration_structure
typedef enum VkClusterAccelerationStructureGeometryFlagBitsNV {
VK_CLUSTER_ACCELERATION_STRUCTURE_GEOMETRY_CULL_DISABLE_BIT_NV = 0x00000001,
VK_CLUSTER_ACCELERATION_STRUCTURE_GEOMETRY_NO_DUPLICATE_ANYHIT_INVOCATION_BIT_NV = 0x00000002,
VK_CLUSTER_ACCELERATION_STRUCTURE_GEOMETRY_OPAQUE_BIT_NV = 0x00000004,
} VkClusterAccelerationStructureGeometryFlagBitsNV;Description
-
VK_CLUSTER_ACCELERATION_STRUCTURE_GEOMETRY_CULL_DISABLE_BIT_NV disables face culling for this geometry.
-
VK_CLUSTER_ACCELERATION_STRUCTURE_GEOMETRY_NO_DUPLICATE_ANYHIT_INVOCATION_BIT_NV specifies that the implementation must only call the any-hit shader a single time for each primitive in this geometry. If this bit is absent an implementation may invoke the any-hit shader more than once for this geometry.
-
VK_CLUSTER_ACCELERATION_STRUCTURE_GEOMETRY_OPAQUE_BIT_NV specifies that this geometry does not invoke the any-hit shaders even if present in a hit group.
