Hi, I have float array data that I want to use to create images in Metal. My plan is to apply one or more shaders to the data, then render it into a new RGB texture and continue from there. I’m using MTLPixelFormatR32Float as the source pixel format with success.
In all the kernel examples I see the sampler returns a float4, which is appropriate for an RGBA format. But my source data/format has no color. What is the equivalent for sampling single float values? I’m currently putting the source data into a 2D texture. Given the use case above, does it make sense to use a MTLBuffer instead and then render that into a new 2D MTLTexture? Thanks!
