Pass:setTallyBuffer
EditSets the Buffer where tally results will be written to. Each time the render pass finishes, the results of all the tallies will be copied to the Buffer at the specified offset. The buffer can be used in a later pass in a compute shader, or the data in the buffer can be read back using e.g. Buffer:newReadback.
Arguments
| Name | Type | Description |
| buffer | Buffer | The buffer. |
| offset | number | A byte offset where results will be written. Must be a multiple of 4. |
Returns
Nothing
Unset the tally buffer.
Arguments
None
Returns
Nothing
Notes
Each tally result is a 4-byte unsigned integer with the number of samples that passed the depth and stencil tests.
If the buffer doesn't have enough room to store all the tallies, the number of tallies copied will be clamped to the minimum number that will fit.
