Shading of the iso surface according to the Blinn Phong shading model:

Note: Semi-transparent iso surfaces require a depth sort, opaque iso surfaces do not (due to occlusion test via Z-buffer)!

Live Demo plus Practice: We use the QtV3 to extract two isosurfaces of the Engine data set for the white and yellow surface respectively!

Two observations:

1. We need shaded iso surfaces
2. We need multiple transparent iso surfaces
