Re: Call Lua functions in an external file

It seems there are some new ones for those that come across this in the future: sim_stringparam_application_path can only be read sim_stringparam_scene_path_and_name can only be read sim_stringparam_scene_path can only be read sim_stringparam_scene_name can only be read sim_stringparam_video_filenam...

Re: V-REP source code on github

One way would be to have a public fork with pro edu and the other public source code, then a private fork for pro that requires an EULA, etc. Both can be based on the same tree, or you could split shared code from private code. I see those decisions & changes will take some time. :-)

Re: V-REP source code on github

Here is the process: (1) Create a personal account representing you, the individual person (the company comes later!) at: https://github.com/join (2) Next, create an account representing the organization that will manage vrep. For example, google chose to put some projects under the google umbrella ...

Re: Conversion of Depth Map to 3D point cloud using Kinect

It is true that Lua is not very fast when you have to manipulate large arrays. So there are several directions you can use: ⋅  You can use LuaJit to make it run faster. As far as I can tell this functionality is only working on Windows (in system/usrset.txt , set useExternalLuaLibrary to ...

V-REP source code on github

Might I suggest creating a github repository with the V-REP source? Right now the source code is just available via the downloads page . It seems many users make small but useful improvements such as new remote API functions, and others larger improvements but they aren't easy to contribute. A githu...

Re: Bullet 3 gpu physics support

cool! They're also very interested in API feedback at this early stage. If there is anything that would make V-REP integration easier you may wish to comment with a github issue. They are incorporating some new ik and constrained opti algorithms for control as well.

Re: Conversion of Depth Map to 3D point cloud using Kinect

Hello, why are you sending a code string instead of sending the float data? I would have a hard-coded function inside of a child script that receives a buffer of ints and a buffer of floats. The ints indicate the size of the respective floats that belong to the depth points or the image data. Of co...

Re: Conversion of Depth Map to 3D point cloud using Kinect

I've got a floating point depth image and an rgb image on the python API, what would be the best way to display it as a point cloud? Right now it looks like calculating the xyz and rgb arrays in python, printing all the data as a lua string that calls simCreatePointCloud and simInsertPointsIntoPoint...

V-REP fails to load certain URDF and SDF files

I tried to load the urdf and sdf files provided for bullet3 example data: https://github.com/bulletphysics/bullet3/tree/master/data/kuka_iiwa When I try to load kuka_with_gripper.sdf I get the following error: <sdf>: <world>: sub element gravity not found In model.urdf vrep seems to choke on the rel...

Re: Bullet 3 gpu physics support

Bullet now has improved physics algorithms designed specifically for robotics which improve the accuracy during interactions such as grasping. In addition to the new python API there is a C and C++ API. https://github.com/bulletphysics/bullet3/releases
