 Author Comment/Response Sal2 12/12/07 02:12am parametricPlot3d not showing up when I use the manipulate command using mathematica 6 sal2 Greetings All I'm using the Clifford parametric equations using the ParametricPlot3D command and they work...but when I use the Manipulate command the image goes blank why is this? Should I be using Plot3d or the Graphic3D command instead? Working Code: umin:=0 umax:=Pi vmin:=0 vmax:=2*Pi xxx:=Cos[u+v]/(Sqrt[2]+Cos[v-u]) yyy:=Sin[u+v]/(Sqrt[2]+Cos[v-u]) zzz:=Sin[v-u]/(Sqrt[2]+Cos[v-u]) ParametricPlot3D[{xxx,yyy,zzz}, {u,umin, umax},{v,vmin,vmax}, PlotRange->All,PerformanceGoal -> "Quality"] Non workinig code when I add the manipulate command to it I'm not sure why: umin:=0 umax:=Pi vmin:=0 vmax:=2*Pi xxx:=Cos[u+v]/(Sqrt[2]+Cos[v-u]) yyy:=Sin[u+v]/(Sqrt[2]+Cos[v-u]) zzz:=Sin[v-u]/(Sqrt[2]+Cos[v-u]) Manipulate[ParametricPlot3D[{xxx,yyy,zzz},{u,umin,umax},{v,vmin,vmax},PlotRange->All,PerformanceGoal->"Speed"], {{u,0,"u Label"},0,30,Appearance->"Labeled"},{{v,0,"v Label"},0,30,Appearance->"Labeled"}] tia sal2 URL: ,
