| 17:59.19 | gabbar1947 | Oh fine. I made an attempt towards HCROSS(), could you please review it and tell me if its acceptable. TIA: |

| 22:35.07 | Stragus | would enjoy providing a little guidance for CSG GPU raytracing |
| 22:35.40 | Stragus | It would be fun to write too, brlcad had me convinced a while ago about the advantages over triangles |
| 22:43.52 | ``Erik | it is a much richer vocabulary for expressing precise geometry... which allows for a correct description to be much smaller |
| 22:45.07 | ``Erik | and, y'know, making things smaller helps make things available to the alu when they're needed, less need for hackery to keep the pipeline fed :D |
| 22:45.19 | ``Erik | (but the pipeline is that much uglier) |

| 22:56.05 | Stragus | I was more convinced by the fact that the acceleration structure can be a *lot* simpler; rays remain more coherent, flow and memory transactions remain coherent |
| 22:56.18 | Stragus | This is far more friendly to GPU and SIMD in general, compared to millions of triangles |
