I already have an
hemisphere.obj 3D model. But I'm trying to build a half-hemisphere (quarter sphere) model. How can I do that? What is the easiest way to do that?
Generally, is there any easy way to create 1/n of sphere?
If you just need it once, I'd suggest you pick up some basic knowledge of a modelling tool. It's very easy to do in Blender:
TAB to enter edit mode. Press
a to clear the selection (which is orange).
DEL and select
For a quarter-sphere: Change view to
Top like in step 3 and repeat steps 6 and 7.
Once you're done editing, hit
TAB to exit edit mode.
File -> Export -> Wavefront (.obj).
Maya experience here. Use a plane or cube to insect with your object. Use boolean operation like UNION,difference, etc to get this.
