I also added the readDepth function from the depth texture example, but changed it a bit so it would return the z distance in view space (so z- in case of Three.js).

WebRay intersection with plane. We are using ray-tracing to create an image of a plane that's defined by the equation, 6x + 5y + z - 30 = 0 6x + 5y + z − 30 = 0. We draw a ray from the … WebThe next step is to calculate when the ray P(t) = O + tD intersects the surface of the sphere. O denotes the position of the camera. You can extend the formula by inserting the point P(t) into equation 4. In the next step, by bringing everything to the left side and expanding it, this equation can be rearranged as follows:
