Canvas3D Picking

Name of Project

Canvas 3D - Picking

Description

To put the project description simply, what it does is that when you click in Canvas 3D, you will select the object that is in the most front in the current camera angle you are looking at. So the details of this Picking project is this:

• Convert the mouse coord in Windows to Canvas coord
• In the current scene, find all objects that intersect where the mouse is clicked
• Find the object closest to the camera from the list of intersecting objects
