How to call my physics simulation timestep function?



  • Hello,

    currently I'm working on embedding the rigid-body physics engine ODE and OpenGl3 into Qt.

    I want my object hierarchy to look like the following
    QApplication
    -GLWidget (draw scene, user input)
    -ODEengine (start/stop, timestep)
    -Scene
    --Box Object
    --Sphere Object

    I am not sure how to call the timestep function of the engine. I am aiming for 100 FPS refresh rate and a timestep size of 0.01, so there is roughly on physic step in each frame.

    Should I implement it with 2 independent timers, one for GL-Rendering and the other for the Physics?
    Is there any standard approach for this?

    I am looking forward for your answers.

    Johannes
