I don't know how to enter these type of expressions as shown in the attached pic. How do I take care of the v & u values so that they are interpreted by K3DSurf?



TIA

Hi,
Those formulas are Parametri surfaces (K3DSurf support two kinds of formulas: Parametric and Iso surfaces). You have to use the "Parametric" page to enter this formula or just save this under a .k3ds file and load it with K3DSurf :
Quote:
X():pi*u + cos(v)
Y():3*v*sin(u)+tan(u)
Z():sin(pi*((u)^2 + (v)^2))/2
[u]:-1, 1
[v]:-1, 1

See the image bellow. Hope this can help Smile
