Hi,
Is that possible to add UNSIGNED_BYTE4 format for output_buffer of Simple Tone Mapper?
I have a D3D/CUDA shared texture, and I use Buffer::map, Buffer::umap and cudaMemcpyToArray to copy the optix output to it. As I don’t need my texture to be HDR and copying UNSIGNED_BYTE4 is faster than copying FLOAT4, I just make the output buffer to be UNSIGNED_BYTE4.
Unfortunately, Simple Tone Mapper only supports FLOAT4 to FLOAT4. Maybe I am wrong, could FLOAT4 to UNSIGNED_BYTE4 be more useful? As many people do tone mapping from HDR to LDR for display.
Thank you very much,
Yashiz
