This is okay.
Animate[Plot3D[h x^2 y, {x, -1, 1}, {y, -1, 1}, PlotRange -> 2,
Background -> Blue], {h, 0, 1, .01}]
But I want a background, in the animation, same the picture in the file attachment. Is it possible?
You can experiment with Overlay.
img = Import["~/Downloads/Background.png"];
Animate[Overlay[{
img,
Plot3D[h x^2 y, {x, -1, 1}, {y, -1, 1},
PlotRange -> 2,
Axes -> None,
ImageSize -> ImageDimensions@img/2]}],
{h, 0, 1, .01}]
Dear Rohit
Thank you very much.
