Re: Smooth versus wobbly driving of Ackermann example with ODE / Bullet

Hi, sorry for the long delay. But I think I figured out what this might be about. In my simulation I have a mesh version of a map (just for visualization) and a big rectangle below it for the physics engine to simulate the car on. The map/rectangle is appr. 14,000.0 x 14,000.0 meters. After I read a...

sim.addScriptText seems to not work any more in Version 3.6

Hi, I have the following function: addAndAttachScript = function(inInts, inFloats, inStrings, inBuffer) sim.addStatusbarMessage("about to attach script") local objectHandle = inInts[1] local scriptType = inInts[2] local scriptContent = inStrings[1] local scriptHandle = sim.addScript(scriptType + sim...

version 3.6 rev0 headless mode seams to crash

Hi, I just downloaded V-Rep 3.6 and tried the headless mode in windows 10 Pro (vrep.exe -h). The program starts but immediately stops with the following exception stacktrace: 11: simWriteTexture - 0x7FFFBBE142A0 10: UnhandledExceptionFilter - 0x7FF82B5ABB60 9: memset - 0x7FF82EE31580 8: _C_specific_...

Smooth versus wobbly driving of Ackermann example with ODE / Bullet

Hi, I'm working with the ackermann example that comes with v-rep. If the simulation uses Bullet (no difference for 2.78 or 2.83), the car's wheels become extremely wobbly at higher (not extreme) velocities. When using ODE, everything stays very smooth. Since Bullet is supposed to be the more modern ...

Position limitations

If I create a vanilla scene (File->new scene) and add a primitive shape (cuboid) to the scene 2 meters above the resizable floor, I get two different behaviors depending on the position of the floor and cuboid. At (0.0, 0.0, zpos) the cube just falls down regularly. If I move the cuboid and floor to...

Re: Enabling spring-damper mode through regular API?

Hi,

I installed the new beta but I'm not sure how I could handle the issue with the new version. I would need some pointers to see what I need to do in order to create spring-damper joints from lua code.

cheers

Re: Enabling spring-damper mode through regular API?

Thank you again for the quick reply. Meanwhile I figured some ways to make changes to the source but I didn't actually include and compile it. So I'm happy that I didn't start with that and read your message beforehand. Since I think I found a quick (and admittedly a little dirty) way to realize the...

Re: Enabling spring-damper mode through regular API?

I just found out that even if I was able to write a custom control loop script for the joint, I wouldn't be able to add this script to the joint (only adding of childscripts is allowed) and also I couldn't change from "PID control" to "Custom control" anyway. I'll try to add the feature myself to th...
