The ray can intersect the triangle or miss it. If the ray is parallel to the triangle there is not possible intersection. This situation occurs when the normal of the triangle and the ray direction are perpendicular (and the dot product of these two vectors is 0). We have learned that the dot product of two perpendicular vectors is 0.

Ray Tracing: Rendering a Triangle (Geometry of a Triangle)

To do so, we simply subtract B from A and C from A. To compute the normal of the plane (which, logically, is the same as the triangle's normal since the triangle lies in the plane) we simply compute the cross product of AB and AC. Remember, these two vectors lie in the same plane since they connect the triangle's vertices.

Let's triangle vertices are V0, V1, V2 Edge vectors are A = V1-V0 B = V2 - V0 Ray has parametric equation (as you wrote) P = R0 + t * Rd From the other side, intersection point has parametric coordinates u, v in the triangle plane P = V0 + u * A + v * B

Ray Tracing Triangular Meshes - York University

triangle is embedded in with each triangle and to share the vertex information amongst neighbouring triangles. The ray intersects the triangle’s plane (a general plane now) and if thet value of the ray’s intersection is reasonable, the actual intersection point is computed: pt =origin +t ⋅ → dir (21 flops).

At the beginning of the function, we compute the dot product of the triangle's normal with the the ray direction. If this dot product is lower than 0, it means that the two vectors are pointing in opposite directions. Thus, the surface is front-facing. If the dot product is greater than 0 the vectors are pointing in the same direction.

Figure 1: we can express the position of P in t, u, v space. t indicates the distance from P to the ray origin and is parallel to the t-axis. if P lies in the unit triangle it means that 0 <= u <= 1, 0 <= v <= 1 and u+v <=1. Let's say that P is the point where the ray intersects the triangle ABC.

The goal of this basic lesson is to learn how to define a polygon mesh in our program (chapter 2) and render this mesh using ray tracing (chapter 3). Mesh Definition Figure 1: a simple mesh with 2 faces and 6 vertices. A polygon mesh is made out of …
Ray Tracing: Rendering a Triangle (Barycentric Coordinates)

return true; // this ray hits the triangle } The plane normal should not be normalized because we use the length of the vector to compute the triangle area. Using Barycentric Coordinates Barycentric coordinates are most useful in shading.
