10/3/2023 0 Comments Convert xyz into zmatrixSo far, I have not figured out how to utilize 3D texture coordinates, and even then, I can't seem to send a 3D matrix to a slab, and then read back into a 3D matrix. Next, and something I know far less about, I am finding information about 3D textures in OpenGL. Both should have an equivalent amount of data, but so far I have not found a way to remap the planes to match the new dimensions. I have gone down a few different paths in working on this:įirst of all, I imagine that I could take a and remap RGB->XYZ, into a. I am attempting to fill a jitter matrix with 3D voronoi (similar to jit.bfg), but on the GPU. (), 'm working with an argb matrix, and would like to convert it into a single plane matrix, mapping rgb to xyz. Names to be given to the columns corresponding to the x and y coordinates and the grid variable in the output ameĪ ame with three columns (names are specified in the colnames argument) giving the x and y coordinates and the attribute values at the locations given by the grid data.
