大家好,我正在使用 Collada 模型中的 kfAnimation 动画。我想包含一个轨迹球控件,但是当我超过堆栈大小时,我不知道为什么我的代码如下
function init() {
initRender();
// Camera
initCamera();
// Scene
initScene();
//controlls
initControls();
initGrid();
loadObjectAnimatedFrames();
window.addEventListener( 'resize', onWindowResize, false );
}
function loadObjectAnimatedFrames(){
loader = loader.load( 'sources/crack-animated.dae', function ( collada ) {
model = collada.scene;
animations = collada.animations;
kfAnimationsLength = animations.length;
//model.scale.x = model.scale.y = model.scale.z = 0.125; // 1/8 scale, modeled in cm
for ( var i = 0; i < kfAnimationsLength; ++i ) {
var animation = animations[ i ];
var kfAnimation = new THREE.KeyFrameAnimation( animation );
kfAnimation.timeScale = 1;
kfAnimations.push( kfAnimation );
}
start();
animate( lastTimestamp );
scene.add( model );
});
}
function initControls(){
controls = new THREE.TrackballControls(camera);
controls.minDistance = 100;
controls.maxDistance = 1800;
controls.addEventListener('change',render);
}
function animate( timestamp ) {
var frameTime = ( timestamp - lastTimestamp ) * 0.001;
if ( progress >= 0 && progress < 48 ) {
for ( var i = 0; i < kfAnimationsLength; ++i ) {
kfAnimations[ i ].update( frameTime );
}
} else if ( progress >= 48 ) {
for ( var i = 0; i < kfAnimationsLength; ++i ) {
kfAnimations[ i ].stop();
}
progress = 0;
start();
}
//pointLight.position.copy( camera.position );
progress += frameTime;
lastTimestamp = timestamp;
render();
}
我试图将控件更新放在 animate 和 start 函数中,但我认为它消耗了大量资源。我也尝试放入渲染但结果相同。
感谢您的帮助,我希望更多的实验可以帮助我。
