i want to load an obj object, then position a camera somewhere in space .
then i want to know which facets of the object (numbered) are visible to the camera,
meaning that the normal is toward the camera and the facet is not behind any other facet.
i guess that this is done automatically all the time in 3dsmax but can i somehow get the info?
thanks in advance
this is my first post so i hope i managed to describe my problem correctly…
