WebMar 3, 2024 · The first derivation involves finding barycentric and ray coordinates simultaneously which results in a 3x3 system. The second chooses to first intersect the … WebThe normal of the plane is also the normal of the triangle. We use the cross product (non-commutative) between A and B to calculate the normal. The equation for the ray is P = O …
Web2. Which normals to use for ray-triangle intersection? The scene file provides a normal for every triangle vertex. However, those normals should NOT be used for ray-triangle intersection. For the intersection calculation, you need to compute the normal of the plane containing the triangle. You do so by taking a cross product of two edges: WebI would first calculate the 2 edges, p0p1 and p0p2, then I'll get the area of the whole triangle (area_p0p1p2). I would then create two vectors from the ray (ray_p0 and ray_p1) and use …
