Hi everyone,
I have a 3D graph, which i can mark points on it, now i need to get the normal vector of each point, or if it is possible even getting the Euler angle. i check the Labview's object library and i found direction cosine to euler, but it needs a transformation to direction cosine matrix. There is other solution by finding the nearest points and make a triangle and then use the vector multiplication to find the normal vector, but finding those points are a new problem itself, so i want to know if there is any better way or even better idea.
