How can mesh faces within a specified bounding box (frustrum) be found?
Similarly to finding objects with raycasting, I need to find faces within a specified 2D box, which defines a frustrum, as seen from the camera.
The frustrum is specified by drawing a box with the mouse, just like the “BoxSelection” example. The only difference is that I need to get a list of faces within this box, instead of objects. Perhaps the BoxSelection example could be adapted to select faces instead?
Any help greatly appreciated.
