instances

CUdeviceptr OptixBuildInputInstanceArray::instances

If OptixBuildInput::type is OPTIX_BUILD_INPUT_TYPE_INSTANCE_POINTERS instances and aabbs should be interpreted as arrays of pointers instead of arrays of structs.

This pointer must be a multiple of OPTIX_INSTANCE_BYTE_ALIGNMENT if OptixBuildInput::type is OPTIX_BUILD_INPUT_TYPE_INSTANCES. The array elements must be a multiple of OPTIX_INSTANCE_BYTE_ALIGNMENT if OptixBuildInput::type is OPTIX_BUILD_INPUT_TYPE_INSTANCE_POINTERS.

instanceStride

unsigned int OptixBuildInputInstanceArray::instanceStride

Only valid for OPTIX_BUILD_INPUT_TYPE_INSTANCE Defines the stride between instances. A stride of 0 indicates a tight packing, i.e., stride = sizeof( OptixInstance )

numInstances

unsigned int OptixBuildInputInstanceArray::numInstances

Number of elements in OPTIX_BUILD_INPUT_TYPE_INSTANCE_POINTERS instances and aabbs should be in...">OptixBuildInputInstanceArray::instances.
