I have a ginormous mesh which I want to cut with multiple planes. For simplicity I want to know how to cut a mesh with single plane and repeat the logic.
X-Y plane of coords
(1,1,0,0) = (a,b,c,d), from the equation
ax+by+cz+d, which is the equation of the plane.
How shall I use this information to cut a mesh? Any help will be invaluable.
