Hi. I have been trying a few hours in blender (polygonal modeling) making a rounded square to connect with a vertex at the center (the center is placed lower than the square). Unfortunately I did not manage to get the shape without some weird reflections. I decided to jump back to Rhino to see if the problem was my lack of knowledge in Blender or my lack of knowledge in geometry.
I can see now with rhino that the shape I want to make will always give me some kind of tension towards the corners of the square:
I did a try also in Blender by intersecting an inverted cone to a cube and I could see the intersection is never straight…then I realize I am trying to force geometry to do something not possible.
Being said that, I was wondering if there is any trick I could get around this. I am trying to design a fruit holder where the center of the square is a point lower than the edge of the fruit holder…kind of an inverted cone surface, but with the difference It will connect to a roundish square profile instead a circle.
Maybe I am able to fake this with a displacement map…but geometry wise is this possible?
