V-REP's GPU usage

Hello, I'm wondering how much GPU power V-REP makes use of. Concretely: Will any of the demos provided with V-REP run faster with a GeForce GT 750M than with an Intel Iris? Are there some features of V-REP that can easily saturate a modern GPU? I'm rather clueless in this domain. The images rendered...

VREP Linux: potentially harmful file permissions

Hello, Looking at the UNIX file permissions in the Linux vrep archive, lots of files are not readable by a user other than the owner or his group. For instance: drwxr-xr-x 2 detryr staff 4096 Oct 2 15:19 platformthemes/ drwxr-x--- 27 detryr staff 4096 Oct 24 22:38 programming/ -rw-r--r-- 1 detryr st...

Re: Fast 3D sensors: sensor resol VS "Extract coordinates" r

Hi, Ok I'll try this tomorrow. I now realize I failed to mention the detail that prompted me to post this question: when I leave the resolution params of the Hokuyo to their default (256/342), it always works fine. That's why my first reaction was to ask if there's a trick in setting these params......

Re: Fast 3D sensors: sensor resol VS "Extract coordinates" r

Hello, that is a strange behaviour. When half of the points are close to zero, is the visual representation correct? I guess there is an error in the way you send the data over to Matlab. Could you show us that code? The problem does not seem to be related to the remote API - When I display the red ...

Fast 3D sensors: sensor resol VS "Extract coordinates" resol

Hi, I see strange things happen with fast 3D vision sensors. Right now, I'm using the Fast Hokuyo. I've set both the vision sensor resolution AND the "extract coordinates" filter resolution to 128. On my Mac, it works fine. On Linux with Matlab 2011, it sometimes works fine. But other time...

Basket model

Hi Marc,

I'm trying to find/create a model of a basket-like object - a simple hollow cylinder, that should respond to collisions (I want my robot to be able to throw objects into the basket). Would you have one lying around? :-)

Thanks,
Renaud.

Speeding up image-related Matlab bindings

Hello Marc, I'd like to submit a patch for the Matlab bindings. Is there a favored channel for patch submission? In the meantime, you will find the patch below. The patch brings the following changes: simxGetVisionSensorImage2 and simxReadVisionSensor extract datapoints from libpointer via matrix op...
