# Obtain a Plot3D in webMathematica?

GROUPS:
 Hello friendsCan any body give me an example to represent a graphics 3D (using Plot3D) in webMathematica?I copied the file Plot3D included in webMathemaica documentantion (https://reference.wolfram.com/webMathematica/tutorial/BasicExamples.html )http://oed.usal.es/webMathematica/Examples/Plot3DLive.jsp , It worked some time ago (years) but now it does´t workI realize at http://library.wolfram.com/webMathematica/Graphics/Plot3D.jsp includes an example of Plot3D but a package called Cluster whose code is not shown is requiered .Guillermo
 The function included in https://reference.wolfram.com/webMathematica/tutorial/BasicExamples.html for Live 3D Plotting is MSPLive3D[Plot3D[fun, {x, x0, x1}, {y, y0, y1}, PlotPoints ->pts]] I realize that using MSPShow instead of MSPLive3D the example works but the graphics can not be moved. I suppose that MSPLive3D requires some add in the browser (Flash?) and this add is not allow in the new version of the browsers. Can someone confirm it?
