Hi All,

I'm currently trying to plot a region of a 3D graph using "RegionFunction". The plot to be cut is generated this way :

ContourPlot3D[f1[x, y, z] == 0, {x, 0, 50}, {y, 0, 50}, {z, 0, 50},] /.Graphics3D[gr_, opts___] :> Graphics3D[GeometricTransformation[gr,PointTrans]];

My GeometricTransformation is properly defined and I'm getting the desired plot. The problem is that a just can't find a way to introduced the RegionFunction :

RegionFunction -> Function[{x, y, z}, PlaneFct < d]

This line is also properly working if use with a simple sphere as this :

ContourPlot3D[x^2 + y^2 + z^2 == 1, {x, -1, 1}, {y, -1, 1}, {z, -1, 1}, RegionFunction -> Function[{x, y, z}, PlaneFct < d]]

Of course, the region is to be remove after the geometric transformation. If someone with more experience than me can help me, I will be forever grateful !

Oh, and is it possible to add another Function in the argument "RegionFunction"? I'm trying to cut my plot with a lot of planes...

Thanks a lot
Bobby
