Re: Why the simulation time goes very slowly?

Thank you! I use vrep to simulate the UAVs control and there are about 200 quadricopters in my scene. The most used functions in my scene are get/setObjectPosition, readVisionSensor and so on. Besides, I use matlab to compute the UAV control algorithm and send the UAVs' velocities to vrep. Then vrep...

Why the simulation time goes very slowly?

Hello, I set the simulation parameters as the default values :Bullet2.7, Accurate(default), dt=50ms(default). However, when i start the simulation, the simulation time goes very slowly. Simulation time add 50ms takes about 3 seconds of the real time. And this cause that the simulation looks very slo...

Re: Making the quadricopter follow a path

Hi, I tried to make the dummy move along the path and followed your steps. But my dummy is not moving and there is no child script in my dummy or path. What is the problem? Cheers Hai, I need to do a similar task. But my dummy is not moving at all when I run the simulation. Here is what all I did;- ...

How to change the information text in the application window?

I try to simulation my own scene and find that the information in the information text is very practical. But there are still some variables don't need to display. And i want to display some other parameters such as the velocities of Quadriqopters and other parameters which defined by myself. This i...

Re: How to speed up the simulation without accuracy loss?

Hi, I try to write a controller to control the quadricopter but i don't know what particlesTargetVelocities means. For example, if i just want the UAV to fly along the X-axis, how could i set the value of particlesTargetVelocities[1],particlesTargetVelocities[2],particlesTargetVelocities[3],particle...

Re: How to speed up the simulation without accuracy loss?

Thanks again. I open the Script Parameters find there are three parameters here: " particlesAreVisible", "fakeShadow", "simulateParticles". Would it make a big difference to my simulation if i turn all of them off? Then i have some questions in quadcopter simulation. I study the control algorithm in...

Re: How to speed up the simulation without accuracy loss?

Hello. Thank you so much for your answer!And there are still some questions. FIrstly, I don't know what are wind particles and how could i turn down the particles. What's more, if i ignore the wind particles, how could it influence my simulation? Then where could i find the cylinder ? The quadcopter...

How to speed up the simulation without accuracy loss?

Hello, I try to use vrep to do some Quadricopter simulations. I use matlab to run the control algorithm and vrep to simulation. The point is that there are more than 50 Quadricopters in my vrep scene and the simulation process is very very slow. But i check my computer and find that the CPU utilizat...
