C Specification
Bits which can be set in VkGeometryNV::flags
, specifying
additional parameters for acceleration structure builds, are:
typedef enum VkGeometryFlagBitsNV {
VK_GEOMETRY_OPAQUE_BIT_NV = 0x00000001,
VK_GEOMETRY_NO_DUPLICATE_ANY_HIT_INVOCATION_BIT_NV = 0x00000002,
VK_GEOMETRY_FLAG_BITS_MAX_ENUM_NV = 0x7FFFFFFF
} VkGeometryFlagBitsNV;
Description
-
VK_GEOMETRY_OPAQUE_BIT_NV
indicates that this geometry does not invoke the any-hit shaders even if present in a hit group. -
VK_GEOMETRY_NO_DUPLICATE_ANY_HIT_INVOCATION_BIT_NV
indicates 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.
