Hi
I have been looking into my Z values and gradients. The step value for Z seems to be very small. Could this be causing the accuracy problem?
Here are a few Z values (x y z) and the corrosponding gradients (dzdx dzdy).
Z values 0.998719 0.998312 0.998353
Gradients 2.51788e-05 -8.87677e-06
Z values 0.998719 0.998683 0.998312
Gradients 2.51717e-05 -8.87782e-06
Z values 0.998683 0.998459 0.998312
Gradients -3.2569e-05 -1.35716e-05
Z values 0.998683 0.998812 0.998459
Gradients -3.25678e-05 -1.35713e-05
I have upload another picture. The background is opengl, whereas my software version on top. The floor is the best place to see what is happening.
