3 I'm trying to write a ray tracer for any objects formed of triangular meshes. I'm using an external library to load a cube from .ply format and then trace it down. So far, I've implemented most of the tracer, and now I'm trying to test it with a single cube, but for some reason all I get on the screen is a red line.

As we suggested before, ray-tracing a polygon mesh which has been triangulated is really simple. We already have a routine to compute the intersection of rays and triangles. Therefore, to test if a ray intersects a polygon mesh, all we need to do is loop over all the triangles in the mesh and test each individual triangle against the ray.

raytracer c++, mesh, ray tracing, ray triangle intersection, raytracing, rendering, Triangle, triangle mesh The triangle class A lot of 3d models used in computer graphics consist of triangles. Almost all 3d modeling software can export to triangulated meshes and so it’s important to support triangles in our raytracer too.

In this case you’ll find the intersect_triangle function inside OptiX SDK 4.0.1\include\optixu\optixu_math_namespace.h. The OptiX SDK contains two APIs, the high-level ray casting API OptiX and the low-level ray intersection API OptiX Prime. In OptiX 4.0.1 the examples are named more clearly to make that distinction.

Since meshes are often stored in a corner table, which is simply an array of triangle fans, this gives an efficient algorithm for ray tracing triangle meshes. The aforementioned algorithm computes ray/triangle intersections with 1 division, 20 multiplications, and up to 18 additions.
