for example if this 3ds file is a cube,to perforate a hole on it,the result will be a cube whose front face and back face all add a circle, am i make the problem clear?

Answer 1

This is a programming website then the answer is... BSP Tree.

Answer 2

if i should calculate the node within the cylinder ?i don't not know the structure of the 3ds file.

Answer 3

it seems that i should calculate the difference of 3ds and a cylinder? that mean i should subtract the cylinder,delete the node within the cylinder ?

am i right?

THanks.
