@pspeed I use a Texture2DArray to store the color and transmittance at each point in the view frustum. The z direction uses 64 to 400 slices, depending on the performance of the GPU. For example, the Gtx 960m can do 128 slices at 1/8th of the screen resolution.
PapaSpace is mainly a research platform for next generation flight simulator visual systems. It is used at the University of Technology in Graz (Austria) but I am also seeking a first contract with flight simulator manufacturers.
Maybe a consumer version will also exist any time soon but I did not consider any details of that plan yet.
@Domenic Yes, I will create a demo video and upload it when ready.
