why just use ch9 in our-full version #75

nihao! Thank you very much for your work. I have a question about the number of channels in ours-full. Why did you only use ch9 in ours-full, instead of channel 16 or 24 or even larger?

In fact, I am also trying to change the number of channels in the 3DGS CUDA renderer. However, I found that when I change the number of channels to 16 or 24, numerical overflow issues occur. Have you encountered this phenomenon?

more channels will reduce the speed of rendering. also 9 channels is easy to initi from rgb input image.

2) i guess error is caused by integer overflow when channel number is too large or pixel number is too large.
