How to represent a line in 3d space
Web2 mrt. 2024 · Let us take two points (x,y,z) and (a,b,c) in space. The line passing through it has direction ratio (x-a);(y-b);(z-c) and using any of the passing point we can specify … WebLet's say I have a line defined by two points, A and B, both in the form (x, y, z). These points represent a line in 3D space. I also have a point P, defined in the same format, that isn't on the line. How would I calculate the projection of that point on to the line? I'm aware of how to do this in 2D but 3D seems to have bugger all resources ...
