Incorrect triangle geometry index type #8

Closed jeffamstutz closed 1 year ago

jeffamstutz commented 1 year ago

triangle geometry should accept ANARI_UINT32_VEC3 indicies, but requires OSPRay's mesh geometry indexing with VEC4.

Error message with valid geometry:

[ERROR][(nil)] ospray::Mesh must have 'index' 1D array with element type vec4ui

Hi, the Ospray Mesh supports both vec3ui(tri mesh) and vec4ui(quad mesh) which map to the Anari vector types. The example "instanced_cubes" uses triangle meshes. The error message when neither were present failed to mention vec3ui. I've opened a PR on the Ospray repo to address this.
