- Create holes in red object
- Slice the red object where its cross section intersects with blue nearby surface.
Red and blue shaepes are tessellated polygons.
In my opinion to fullfill these tasks I need to know whether the following techniques are applicable to Tessellation object.
Is it possible to change the extrusion direction on tessellation applied shape ( kinda nested tessellations). If it’s possible that way I’ll cut holes. (probably feeding new gluNewTess2 object data from resulting/previous gluNewTess1 object )
To get slicing effect: I should know whole vertex data of resulting tessellation shape and after that I may apply vertex projection on plane, 3D volume slice etc… but the key point is vertex data manipulation of resulting tessellation shape.
Any help will be appreciated so much cause I’m really stuck at that!
