- Subject: [cgal-discuss] 3D Boolean operation with float data
- Date: Thu, 10 Jun 2010 18:14:35 +0200 (CEST)
Hello!
I am new to CGAL and i am having some questions about 3d boolean operation.
I have OFF files describing simple 3d objects (box), All the coordinate are
describe in float.
the two box are adjacent!
My program so far consists of:
- built polyhedron from OFF
- converting Polyhedron to Nef_polyhedron
- Add the Nef polyhedron
- display result
This work well, but the result polyhedron is more complex(in number of faces)
has expected.
After investigation, I discovered that my two coordinates common objects were
not all completely identical ( a difference after 3 numbers under comma).
i use a Exact_predicates_exact_constructions_kernel.
What's the solution for the boolean operation see 2 points like: P1(2.1547
1.7897 2) P2 (2.1548 17897 2) identical?
Is the role of the kernel to do that?
Best regards,
Damien
