Hello
I’m sorry to bother you, I want to use ffmatlib3D to draw a cross-section of a 3D function, but I don’t know how to select the section. I want to know which parameters are used to select the section. Is it S1, S2, S3 in the figure below?
For example,
u=xyz*(1-exp(-(1-x)/epsilon))(1-exp(-(1-y)/epsilon))(1-exp(-(1-z)/epsilon))
I want to draw the figure of z=1 in the numerical solution of u. How should I adjust the parameters in S1, S2 and S3?
It sounds like they are three points that define the plane containing the cross section? So you should define three non-colinear points in your plane of interest. Note that this is a guess since I haven’t actually used this function
