       | Great piece on iq's work on Pixar's brave that gives a sense of
       | how unusual his approach was:

       | 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.

       | 3DOF remove for interactions)

       | 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?

         | been written about how it works.

           | the stored operations that generate it.

       | 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.

         | 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?
