Our host-side math backend is pretty chaotic. A lot of it was taken from Falcor. At some point, I'd like to more directly integrate Slang's math library which comes bundled with the Vulkan SDK. In the interim, hacks are welcome. |

VectorTypes.hto also include definitions fordouble1,double2,double3anddouble4for use within GPRT shaders.As part of the XDG project, we would like an implementation of double precision ray tracing using GPRT similar to the h5m-reader. In the past, it seems GPRT also included a
linalg.hheader, see gprt @ 77642f2 which was used within the h5m-reader to create double precision buffers.At some point though the
linalg.hheader has been replaced by the math utlities found here https://github.com/gprt-org/GPRT/tree/master/gprt/math, which do not currently include any definitions for vectors of doubles.This may be missing some additional utility/functions but as far as a I can tell it does work.
