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.

So first you take your ray k+tl, and find the value of t where that ray intersects with that plane. That appears to be what your code chunk is doing. …

If we replace P in equation 1 with the ray's equation we get (equation 3): O + t D = A + u ( B − A) + v ( C − A) O − A = − t D + u ( B − A) + v ( C − A) On the left side of the equal sign, we have three unknowns (t, u, v) multiplied to three known terms (B-A, C-A, D).

Barycentric ray-triangle intersection • Every point on the plane can be written in the form: for some numbers β and . • If the point is also on the ray then it is for some number t. • Set them equal: 3 linear equations in 3 variables …solve them to get t, β, and all at once! 9 p + td a + (b a)+(c a) p + td = a + (b a)+(c a)

Ray-triangle intersection • Condition 1: point is on ray • Condition 2: point is on plane • Condition 3: point is on the inside of all three edges • First solve 1&2 (ray–plane intersection) – substitute and solve for t: 10

‘ t ‘ is the parameter you use to define your ray equation: intersection_point = position + (t * direction); You know your position and direction vectors already, ‘ p ‘ and ‘ d ‘, so re-write the code above to tell you what ‘ t ‘ is. Then plug that value of ‘ t ‘ into the ray equation I wrote above, and hey presto, you have your intersection point.

where a ray with origin P and direction d intersects a triangle defined by its vertices, A, B, and C at intersection point Q. The square region diagrammatically surrounding triangle ABC represents the supporting plane of the triangle, i.e., the plane that the triangle lies on. To perform ray-triangle intersection, we must perform two steps: 1.
