WebOct 22, 2016 · The intersection point with the ray, if it exists, is given by solving n ⋅ (y(t) − (x1, y1, z1)) = 0 for t ≥ 0. Lastly, you have to check if the intersection point lies on the triangle. … WebThe technique of volume ray casting can be derived directly from the rendering equation. It provides results of very high quality rendering. Volume ray casting is classified as an image-based volume rendering technique, as the computation emanates from the output image and not the input volume data, as is the case with object-based techniques.
