public void UpdateInstanceTransform (Renderer renderer);

파라미터

renderer The Renderer associated with a ray tracing instance.

설명

Updates the transformation of a ray tracing instance.

For a ray tracing instance associated with a Renderer component, Unity retrieves the transformation from the Transform component.


public void UpdateInstanceTransform (int handle, Matrix4x4 matrix);

파라미터

handle The handle associated with a AABB or Mesh ray tracing instance.
matrix The new transformation matrix of the ray tracing instance.

설명

Updates the transformation of a ray tracing instance.

Pass along a new transformation matrix and the handle RayTracingAccelerationStructure.AddInstance returns in order to transform a ray tracing instance associated with a axis-aligned bounding box (AABB) GraphicsBuffer or a Mesh.

Access the transformation matrix in shader code using WorldToObject() or ObjectToWorld() HLSL functions.

To trigger an acceleration structure build on the GPU, call RayTracingAccelerationStructure.Build or CommandBuffer.BuildRayTracingAccelerationStructure.
