orthographic (No Perspective) Hidden Point Removal

Post by geolux »

Hi friends,
Some time ago, I asked why the plug for remove hidden points don't work in Orthographic Projection but only in Perspective , so I think that this is a important new function to add in CC.
In fact, this function would be interesting in every case where you must draw an orthographic projection (vertical or orizontal) with Render to File. In architecture use is very very needful
thank you

The issue is that Katz's algorithm (HPR) can't work in orthographic projection mode...
(see http://www.wisdom.weizmann.ac.il/~ronen ... 20Sets.pdf)

One would have to find another method in this case.
