| Description | |
|---|---|
| world | World. |
| positions | BufferSlice containing the probe positions to integrate. |
| pushoff | The offset to add to the rays traced from each probe position. You can use this parameter to prevent self-intersections when 32 bit floating point precision is an issue, for instance when integrating a large open world. |
| bounceCount | Number of light bounces. |
Prepare the integrator.
The preparation can take a significant time if the world is large or OpenCL kernels haven't been written to cache yet.
