Hope he lives to | be 120 and keeps it up. | andybak wrote: | Raymarching stuff looks incredible in VR but most of the | available examples are web-based and the overhead of WebGL for a | technique that relies on raw GPU throughput often kills it. | | Someone really needs to update this to work with current headsets | and controllers: https://github.com/jimbo00000/RiftRay | | (it works on the Rift last time I checked but uses the original | 3DOF remove for interactions) | HammadB wrote: | I think it's interesting to explore how different data | representations in computer graphics are taking advantage of ever | improving GPUs to enable new applications/workflows. The two I | know of most are SDFs and Image-based rendering techniques like | light fields, primarily as Neural Radiance Fields. Are there any | other interesting ones emerging? | corysama wrote: | PS4's _Dreams_ is pretty advanced voxel tech. Quite a bit has | been written about how it works. | cma wrote: | It uses SDFs as well, in both the voxel representation and in | the stored operations that generate it. | rsp1984 wrote: | I was actually looking for some resources on this but | couldn't find much. Do you have any pointers? I saw Alex | Evan's excellent talk from 5 years ago [1], which sparked my | interest. | | [1] https://www.youtube.com/watch?v=u9KNtnCZDMI | Cmortoc wrote: | For anyone interested in computer graphics, I find Inigo Quilez's | site (https://iquilezles.org/www/index.htm) more helpful than | most of the textbooks on my shelf. | tempnowreal wrote: | Im very interested to learn about computer graphics but the | more I look into it I kinda feel its a niche field and not much | strutted resource or curriculum is available. Would you have | any tips on where I should start? | foo_barrio wrote: | These types of sites are where I too learned most of the | graphics programming I know.
