Constructor Detail

Texture3D

public Texture3D(Buffer buffer,
                 int[] shape,
                 float min,
                 float max,
                 ColorMapper mapper,
                 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

min - the minimum V value provided in the input buffer which must be set consistently with the colormapper

max - the maximum V value provided in the input buffer which must be set consistently with the colormapper

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

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

Texture3D

public Texture3D(Buffer buffer,
                 int[] shape,
                 ColorMapper mapper,
                 BoundingBox3d bbox)

A convenient constructor that configure the volume value range based on the colormapper settings. Texture3D(Buffer, int[], float, float, ColorMapper, BoundingBox3d)
