This distance is actually the length of the perpendicular from the point to the plane. Here (look for [edit2]) you will find the cross , dot and || equations used if needed: so if I put all together in code like form: Thanks for contributing an answer to Stack Overflow! We can clearly understand that the point of intersection between the point and the line that passes through this point which is also normal to a planeis closest to our original point. I assume you want to compute perpendicular distance between point and plane given 3 points on it forming a triangle. \[\overrightarrow {PQ} = \left\langle {2,3,4} \right\rangle … So, one has to take the absolute value to get an absolute distance. Here vector math approach: let the triangle points be p0,p1,p2 and tested point p. first we need to obtain plane normal, that is simple vector multiplication of any two non parallel and non zero vectors inside the plane: and normalize it to unit vector (to simplify stuff): we can exploit dot product for this so just crate a vector going from any point on the plane into your tested point and dot with unit normal ... the last absolute value (on scalar distance) will just get rid of the sign of the result which tells you if the point p is in direction of normal n or in opposite one sometimes such info is wanted so in such case remove the outermost abs value and use polygon winding and cross product operands order to maintain wanted normal direction. It is the length of the line segment that is perpendicular to the line and passes through the point. Spherical to Cartesian coordinates.
