Constructor Details

Volume

public Volume(FloatBuffer buffer,
 int[] shape,
 BoundingBox3d bbox)

Instanciate a drawable volume.

Parameters:

buffer - provides (x,y,z,V) tuples where (x,y,z) are voxel index in the volume and V the value used for coloring voxels

shape - a 3 element array indicating the number of voxels for each dimension

bbox - the real world range of each axis, since the input buffer provide tuples with index and not coordinates

mapper - the colormap handler that will apply a colormap to a value range
