I'm enjoying SurfX3D. For some reason I can't plot the cube in implicit form : max(abs(x),abs(y),abs(z))-1. Am I doing something wrong?

The equation that you want to plot is the definition of the cube surface. This is the reason why you can't use it to plot the cube. The program was tested and no error was encountered while plotting. Try to use another cube equation. You should be able to obtain a cube.

SurfX3D Implicit Form F(x,y,z) requires the equation to produce a sign change to detect a surface.
If the equation does not produce a sign change for F(x,y,z),
then there will be no surface detected or drawn.
