[JAVA3D] how does Java3D determine the grid surface -resent

I guess that everyone is busy for the holiday. But I am going to re-send this question again. To make it clearer, I would like to know how I can find out the elevation of the center of the grids. Does Java3D interpolates the Y using some formula? Thank you for your time! and Merry Christmas! Happy

Lan: As far as the actual surface geometry is concerned, I believe Quadrilateral and Triangle surfaces are linear interpolation between the corner point locations. I think I remember reading that the rendering of a non-planar (not all 4 corners lie on a single plane) Quadrilateral may produce unde

Hi all, is there a way of starting an Interpolator object after another is done is finish doing is loop. I want the two interpolator to start and each other when there finish doing one loop of animation. I know you can do that with a behavior object in the processstimulus function but is there a

Thank you for your quick response. That is what I thought too. I did use the mid point between the two vertices that form the triangle. It seems not right. But Now I use the same triangles that I used to define the ground and rotates each triangle to the actual orientation, and it works fine. Thank
