I am trying to make an animation in which a mathematical function changes as a function of time. Given below are two images which are z math surfaces(from the "extra objects" add on) whose equations are:
The first image should change in the other for which the mathematical function can be given as $\sin x+t\cos y$, where $t$ varies from $1$ to $-1$
This is a simple mathematical surface parametrized in $t$ ($t$ obviously is a function of time and in our case a function the frame number).
Here I have picked up simple equations just to get the idea of implementing it and I actually intend to use it for more complex functions and even for the XYZ math surface. How do I go about it? (I would prefer a way without scripting but if I have to use scripting then please tell me in detail as to how to proceed with it.)
