Declaration
init(transformationMatrix: MTLPackedFloat4x3, options: MTLAccelerationStructureInstanceOptions, mask: UInt32, intersectionFunctionTableOffset: UInt32, accelerationStructureIndex: UInt32)Parameters
- transformationMatrix:
The transform for placing and orienting the instance in the scene.
- options:
The options for this instance.
- mask:
A mask to use for this instance when testing a ray against the geometry.
- intersectionFunctionTableOffset:
An offset to apply to the intersection function table when testing a ray against this instance.
- accelerationStructureIndex:
The index of the acceleration structure to use for this instance.
