C Specification
The VkPhysicalDeviceRayTracingPropertiesNV
structure is defined as:
typedef struct VkPhysicalDeviceRayTracingPropertiesNV {
VkStructureType sType;
void* pNext;
uint32_t shaderGroupHandleSize;
uint32_t maxRecursionDepth;
uint32_t maxShaderGroupStride;
uint32_t shaderGroupBaseAlignment;
uint64_t maxGeometryCount;
uint64_t maxInstanceCount;
uint64_t maxTriangleCount;
uint32_t maxDescriptorSetAccelerationStructures;
} VkPhysicalDeviceRayTracingPropertiesNV;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to an extension-specific structure. -
shaderGroupHandleSize
size in bytes of the shader header. -
maxRecursionDepth
is the maximum number of levels of recursion allowed in a trace command. -
maxShaderGroupStride
is the maximum stride in bytes allowed between shader groups in the SBT. -
shaderGroupBaseAlignment
is the required alignment in bytes for the base of the SBTs. -
maxGeometryCount
is the maximum number of geometries in the bottom level acceleration structure. -
maxInstanceCount
is the maximum number of instances in the top level acceleration structure. -
maxTriangleCount
is the maximum number of triangles in all geometries in the bottom level acceleration structure. -
maxDescriptorSetAccelerationStructures
is the maximum number of acceleration structure descriptors that are allowed in a descriptor set.
Description
If the VkPhysicalDeviceRayTracingPropertiesNV
structure is included in
the pNext
chain of VkPhysicalDeviceProperties2, it is filled
with the implementation-dependent limits.
