为什么我调用Canvas3D.repaint()时Java3D画布会闪烁? [英] Why does the Java3D canvas flicker when I call Canvas3D.repaint()

问题描述

我在Java3D画布上使用postRender()绘制了2D元素，并希望对其进行动画处理.在循环中，我调用Canvas3D.repaint():

I have 2D elements I draw with postRender() on a Java3D canvas and want to animate these elements. In a loop I call Canvas3D.repaint():

while(animationIsRunning){
    // I update positions of 2D elements here...
    // ...
    canvas3D.repaint();
    Thread.sleep((long)(1.0/30.0 * 1000));
}

对于每个简短的动画，这都会导致整个3D画布闪烁一次或两次.

For every short animation, this causes the whole 3D canvas to flicker once or twice.

推荐答案

我认为我找到了一种解决方案:

I think I found a solution in my case:

代替

canvas3d.repaint();

我调用

canvas3d.getView().repaint();

这样，我可以以高帧频更新动画而不会闪烁.

This way I can update my animation with high framerate without flickering.
