Potential memory leak problem with the vision sensor

Hi there, I am using VREP v3.6.2 to generate a bunch of images. It was fine at first but after thousands of rounds, the memory it consumed became so big. Then eventually, the system crashed.

Re: Coordinate transformation from camera frame to world frame

Hi there, I'm trying to transform coordinates from camera frame to world frame.

How to keep two objects relatively static via Script

Hi there, I'm trying to create two objects A and B, then keeping B's position/rotation relatively static with A. It is pretty easy via GUI, I just need to set A as B's parent and everything is fine. However, I want to use the script to do that. I only set A as B's parent in the very beginning in the...

However, when I started the V-REP program in the new system, it showed: Initialization failed (registerScriptStuff): simRegisterScriptVariable: error In...
