Lights in MuPAD and JavaView
White sphere with default MuPAD lights
Sphere is another type of MuPAD object. It contains a number of polygons but edges of these polygons are hidden. Therefore, sphere interacts with light in a bit different way than a box or a parametric surface.
MuPAD
Image obtained in MuPAD using default lights.
JavaView
The same model converted to JavaView without any improvements. A major problem of this model is visible equator of the sphere. This is the internal boundary where top and bottom values of one of the the sphere equation parameters meet.
JavaView
The same model with JavaView default lights plus one ambient light (0.2). NOTE: the model was loaded to JavaView and using Method>Modeling>Identify Vertices I removed the internal boundary. This way I was able to remove the equator of the sphere.
