Cutting Planes
← Cross Section Example | ● | Tetrahedra →
Cut of an arbitrary plane with a unit volume:
- polygon with 3 to 6 corners
- view-dependent
- Vorteile:
- Interactive manipulation of the plane.
- No restriction to axis-aligned planes.
- Disadvatages:
- no simple manual positioning of the plane (parametrized by pivot point and normal)
- 8 bit quantisation artifacts.
- 16 bit 3D textures available on graphics hardware, but much slower.
- Limited texture memory.
- NVIDIA GeForce GTX resp. ATI Radeon have 512MB to 1GB and up.
- A 16 bit volum with 512×512×600 voxels already has 300 MB.
- A $1024^3$ 16 bit volume even has 2 GB.
