Hi, I need help to figure out why my UI behaves strange on workbench. The menu system that I write using UI toolkit works fine in my computer. But when I test on the workbench, there comes the situations below.

1)If I translate the menu to various positions but not in the coordinate"0 0 0", when the haptic point to a button, it might be another button showing to be pointed and give some wrong feedback. And it feels like the haptic works not so smoothly on the UI . Besides, there's stiffness on edges outside of the buttons and that area can be pointed to and acts like buttons, these are all not expected.

2)If the menu system is in the translation="0 0 0", the buttons act correctly when the haptic touches them and the haptic act good on the UI. But still, there's stiffness on edges outside of the buttons and that area can be pointed to and acts like buttons, these are all not expected.

How can I solve the problems above?

Thanks in advance.

Seems like some kind of scaling going on in your scene, do you use non-uniform scaling in some place?

Do both systems use the same H3DAPI settings (same viewpoint, same device, same stereo-settings?)

I'll reply since I'm involved in this project and set up the system she's talking about.

There is no strange scaling of the scene, however the system uses head tracking which means that there will be an asymmetric frustum. The frustum should only affect the graphical rendering unless some strange connection that I'm not aware of between the OpenGL context and the haptic rendering is used in H3D.

Was this issue solved, and if so, on time?

[EDIT] Typical, I should have read the other forum posts before posting this one. I noticed there that this issue is fixed.

Well, there were still strange behaviours. If I recall it correctly we had to use buttons instead of sliders because the sliders didn't work correctly. We are no longer working on this project, though.
