Hello,
My today's problem is that I am creating plugin which compares a wall and a point cloud. And i want to know if the point cloud point is in front of the face or behind the face. I Don't know if there is a tool which indicate the positon of a point compared to a face or a wall. And if there is no tool if someone can help me find a mathematical way to determine if the point is in front of or behind the face.
I already compute the distance between the wall and the point cloud, the last thing that I have to do is to find if it is in front of or behind the face.
