Slices

Slices is a simple volume rendering core. The Slicer just creates and renders viewer-oriented slices from back to front through a rectangular volume, which is centered around the origin and specified using the size in the three dimensions. The numberOfSlices parameter defines the number of slices which should be utilizes along the diagonal. Therefore it is more the max number of slices rendered and should be set to match the texture sampling rate. The slice distance is uniform for different camera positions which is necessary to minimize the re-sampling artifacts.

The core depends on the material to setup a 3D texture and BlendMode. You have to provide the voxelgrid-data as 3D-Texture. Check out the testSlicer programm as example.
