You can write a plugin in C++ providing one or more custom Lua commands, and use whatever image processing algorithm (e.g. OpenCV, TensorFlow, ...) to extract the info you need.

Oh, I think this is related to the fact that V-REP changes the working directory on startup (so relative paths are in fact relative to V-REP directory).

Can you try to use file:// scheme with absolute paths?

I will provide a fix for relative file:// URIs.

A relative URI should be file://meshes/CAD/link_Lf_thigh.stl, not file:///meshes/CAD/link_Lf_thigh.stl

That is correct. In C++ there are only the xxx_cast<...>(...) operators.

You can open the SDF file in a text editor and replace the model:// with file:// in the URI which is failing to resolve

Hi Smitty44, model:// URIs should be in the form model://package/path , for example model://mypackage/meshes/cad/test.stl, so your directory structure should be: path/to/mypackage/file.sdf path/to/mypackage/meshes/cad/test.stl Alternatively, you can use file:// URIs (more reliable), which allow you ...

Hello,

thanks for reporting this issue.

A few questions:

• Does it happen always (i.e. when trying multiple times)?
• Does it happen with any SDF model?
• Can you share a SDF model which causes the crash?

Hello,

you can use this as a starting point: https://github.com/fferri/v_repExtSDL

It uses SDL2 to access the joystick device

Thanks!

Now fixed in GitHub repo.
