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. The roof is sloped and I can create the sloped roof plane but I am unsure how to get the distance from the point to perpendicular to the theoretical roof slope, not the difference in elevation.
