[SOLVED] SofaHAPI and Mouse Interference

[Sen]

Hi ,

I am trying to use the SOFAHapi Plugin.
I can get the SofaHAPI01 example scene loaded.
I connect a ForceDimension Omega 3 device to my pc and When I runSofa

I get 2 strange errors.
a) “Plugin …../sofabin/bin/SofaHAPI_1_0.dll method initExterna
lModule() NOT FOUND” .

b) But I also see that my device pointer moves ( in ajerky fashion) only when my mouse is also moved. This suggests some kind of USB collision. Has anyone experienced this.
Theres no force feedback anyway

QtViewer: disabling vertical refresh sync
QtViewer: OpenGL 3.1 context created.

Dear Sen,

I have never tested ForceDimension devices with SOFA, but I know that in Strasbourg, they did it at some points.

I can only provide incomplete answers:
+ Plugin …../sofabin/bin/SofaHAPI_1_0.dll method initExternalModule() NOT FOUND
It seems that a commit of May 6 has introduced a bug in the init of the plugin.
Could you confirm that you are using a version of after May 6 ?
We will commit a revision (to go back to the previous version) this afternoon…

+ Conflict with your mouse is really strange !!
Do you have the same conflict on other applications that use ForceDimension devices ?

Dear Sen,

If you have no additional questions, or answers, I will close this thread.
Best,

Hugo

PS: do no forget in your scenes to define the tolerance, iterations and threshold parameters of the conjugate gradient ! it is key for the convergence of your simulation.
