Re: make IK solver ignore rotation around one axis only

... update: having thought about this - i can probably just put an extra revolute joint between the tip of the tool and the target. this should provide me with the extra degree of freedom for a little extra computational load.

make IK solver ignore rotation around one axis only

dear forum, i'm in the process of doing an analysis of reach for a spindle that will be mounted on a robot. an image of the spindle is given below: https://drive.google.com/file/d/1u4GM3vqRxlEoc85ProB47gwemqD319Tj/view?usp=sharing since the tool is rotationally symmetric around the z axis of the coo...

Re: Simulator won't run on Ubuntu 20.04 64-bit - Undefined symbol

As a side note: should you want to run the coppeliaSim binary directly (e. g. for headless simulations or if you want gdb/valgrind it), you can first run source coppeliaSim.sh to set the environment variables correctly in your shell session. After this, you can start the binary directly (in that one...

Re: ExtOMPL compiling and using

Hi, After successful comppilation, you get a shared library that is supposed to go into CoppeliaSim's root folder. CoppeliaSim then loads its libraries directly form there. Compiling on WSL will probably give you an *.so file as the result which will not work on Windows - you need *.dll. I have no e...

Re: simAssimp.exportMeshes ignores upvector

update: sorry, it was me who mixed up y and z upvectors. it's now fixed in my fork.

Re: simAssimp.exportMeshes ignores upvector

hi, at least to me, the issue still seemed to be present in the repo. i created a pull request with corrections that work for me. one issue, however, remains with importing meshes through the menu (file->import->mesh). the behavior of choosing y or z as upvector seems to be reversed in my opinion. c...

Re: simAssimp.exportMeshes ignores upvector

... and a small addendum: simAssimp.exportMeshes also seems to ignore the provided scaling factor.

cheers!

simAssimp.exportMeshes ignores upvector

hi, i ran into some trouble when exporting meshes from coppeliaSim. when using simAssimp.exportMeshes , it seems to ignore the simAssimp.upVector parameter and to always export with the upvector being Y. when importing these geometries into other software (e. g. blender), this leads to the mesh bein...
