Here is an example how to use Dynamic inside Manipulate for smooth rotation. But it does not work for the following code. Manipulate[ Show[Graphics3D[Cube[]], ViewPoint -> RotationMatrix[Dynamic@fi, RotationMatrix[Dynamic@fi, {0, 1, 1}] . {0, 0, 1}] . {1.3`, -2.4`, 2.`}], {fi, 0, 2 Pi}] It can be solved by wrapping whole view point expression by Dynamic instead of using Dynamic@fi. Manipulate[ Show[Graphics3D[Cube[]], ViewPoint -> Dynamic[RotationMatrix[fi, RotationMatrix[fi, {0, 1, 1}] . {0,...
