Visualization Techniques for a Three-Dimensional Domain

This is the case of a sampled function F(x1,x2,x3), with each sample returning a scalar. This area is sometimes called Volume Visualization.

IsoSurfaces: ES3

This is similar to contour lines for the 2D case, but now a new surface of constant values is generated.

 

Volume Rendering by Ray Casting: ES3

Color and partial opacity are assigned to each voxel by some method. The final pixel value is obtained by summing the appropriate voxel values. An example of volume rendering.
