Writes the primitive_index to a secondary render target and uses that to highlight the primitive that the pointer is over on subsequent frames.

This is great!
I think it might be nice to add a few more comments in the code. I also notice lots of inconsistent formatting like a: b vs a : b and a + b vs a+b. I don't mind but just thought I'd point it out. npm run lint though does complain about some things though.

Updated with more comments all around, as well as addressing your feedback. I think the formatting issues you pointed out were in the WGSL files, which is why they weren't showing up for my with lint. |

Writes the
primitive_indexto a secondary render target and uses that to highlight the primitive that the pointer is over on subsequent frames. Also includes a mode that visualizes the primitive index. Used as a (somewhat contrived) example of using theprimitive_indexbuiltin.This was based on the deferred shading sample, but has been modified significantly.
