BLASBuildTriangleData struct
Triangle geometry data description.
Contents
- Reference
Public variables
- const char* GeometryName
- Geometry name used to map a geometry to a hit group in the shader binding table. Add geometry data to the geometry that is allocated by BLASTriangleDesc with the same name.
- IBuffer* pVertexBuffer
- Triangle vertices data source. Triangles are considered "inactive" if the x component of each vertex is NaN. The buffer must be created with BIND_RAY_TRACING flag.
- Uint32 VertexOffset
- Data offset in bytes in pVertexBuffer.
- Uint32 VertexStride
- Stride in bytes between vertices.
- Uint32 VertexCount
- The number of triangle vertices. Must be less than or equal to BLASTriangleDesc::
MaxVertexCount. -
VALUE_
TYPE VertexValueType - The type of the vertex components. This is an optional value. Must be undefined or same as in BLASTriangleDesc.
- Uint8 VertexComponentCount
- The number of vertex components. This is an optional value. Must be undefined or same as in BLASTriangleDesc.
- Uint32 PrimitiveCount
- The number of triangles. Must equal to VertexCount / 3 if pIndexBuffer is null or must be equal to index count / 3.
- IBuffer* pIndexBuffer
- Triangle indices data source. Must be null if BLASTriangleDesc::
IndexType is undefined. The buffer must be created with BIND_RAY_TRACING flag. - Uint32 IndexOffset
- Data offset in bytes in pIndexBuffer.
-
VALUE_
TYPE IndexType - The type of triangle indices, see Diligent::
VALUE_TYPE. This is an optional value. Must be undefined or same as in BLASTriangleDesc. - IBuffer* pTransformBuffer
- Geometry transformation data source. The buffer must be created with BIND_RAY_TRACING flag.
- Uint32 TransformBufferOffset
- Data offset in bytes in pTransformBuffer.
-
RAYTRACING_
GEOMETRY_ FLAGS Flags - Geometry flags, se Diligent::
RAYTRACING_GEOMETRY_FLAGS.
