| Parameter | Description |
|---|---|
| handle | The handle associated with the ray tracing instance. |
Only ray tracing instances that use RayTracingMode.DynamicGeometryManualUpdate can use this function to update their geometry.
To trigger an acceleration structure build on the GPU, call RayTracingAccelerationStructure.Build or CommandBuffer.BuildRayTracingAccelerationStructure. After invoking one of these functions, the geometry is not considered dirty anymore.
