VolumeRendering
Axis-Aligned Cross Sections
← View-Aligned Planes | ● | Cross Section Example →
Most simple display of a volume:
Axis-aligned cut of a plane with a volume.
- Volume function f(x,y,z) is defined by 3D luminance texture.
- Axis aligned cut of the plane with the unit cube yields geometry to be rendered.
- Graphics hardware rasterized geometry with the data from the 3D texture.
- Tri-linear interpolation by graphics hardware.
Example:
- Plane intersection with 2 or 3 axis-aligned cut planes (MPR = multi-planar reconstruction).
Advantages:
- Intuitive plane positioning
- Plane intersection can be moved interactively.
Disadvantage:
- No arbitrary plane positioning.
