我读过其他关于变形顶点的文章,特别是我的其他文章。然后我想出了这个代码,但仍然有错误,我找不到当前问题的答案。
我在https://github.com/mrdoob/three.js/blob/master/src/loaders/JSONLoader.js上阅读了这个例子并在那里使用了代码。然而,仍然存在一些问题,我甚至不知道这似乎是什么问题。
代码:
<script src="js/three.min.js"></script>
<script type=text/javascript>
var camera, scene, renderer;
var geometry, material, mesh, loader;
//decalaration of javascript variables thru PHP Declaration
var customHeight = "<?php $height = ($_POST['height'])*20; print $height; ?>";
var customWidth = "<?php $width = ($_POST['width'])*20; print $width; ?>";
var init = function() {
//camera
camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 10, 10000 );
camera.position.z = 1000;
//scene
scene = new THREE.Scene();
//renderer
renderer = new THREE.CanvasRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
renderer.setClearColor(0x404040 , 10);
document.body.appendChild( renderer.domElement );
customHeightWidth(customWidth, customHeight);
function customHeightWidth(width, height){
//loader
loader = new THREE.JSONLoader();
//material
material = new THREE.MeshBasicMaterial({
color: 0xffffff,
side: THREE.DoubleSide,
overdraw: false,
morphTargets: true,
wireframe: true
});
//loader function
loader = function ( showStatus ) {
THREE.Loader.call( this, showStatus );
this.withCredentials = false;
};
THREE.JSONLoader.prototype.load = function ( url, callback, texturePath ) {
var scope = this;
// todo: unify load API to for easier SceneLoader use
texturePath = texturePath && ( typeof texturePath === "string" ) ? texturePath : this.extractUrlBase( url );
this.onLoadStart();
this.loadAjaxJSON( this, url, callback, texturePath );
};
var xhr = new XMLHttpRequest();
var json = JSON.parse( xhr.responseText );
THREE.JSONLoader.prototype.parse = function ( json, texturePath ) {
var scope = this,
geometry = new THREE.Geometry(),
scale = ( json.scale !== undefined ) ? 1.0 / json.scale : 1.0;
parseMorphing( scale );
function parseMorphing( scale ) {
if ( json.morphTargets !== undefined ) {
var i, l, v, vl, dstVertices, srcVertices;
for ( i = 0, l = json.morphTargets.length; i < l; i ++ ) {
geometry.morphTargets[ i ] = {};
geometry.morphTargets[ i ].name = json.morphTargets[ i ].name;
geometry.morphTargets[ i ].vertices = [];
dstVertices = geometry.morphTargets[ i ].vertices;
srcVertices = json.morphTargets [ i ].vertices;
for( v = 0, vl = srcVertices.length; v < vl; v += 3 ) {
var vertex = new THREE.Vector3();
vertex.x = srcVertices[ v ] * scale;
vertex.y = srcVertices[ v + 1 ] * scale;
vertex.z = srcVertices[ v + 2 ] * scale;
dstVertices.push( vertex );
}
}
}
mesh = new THREE.Mesh(geometry, material);
scene.add( mesh );
}
};
var animate = function() {
requestAnimationFrame(animate);
//mesh.rotation.x += 0.01;
//mesh.rotation.y -= 0.05;
renderer.render(scene, camera);
}
init();
animate();
</script>
答案 0 :(得分:0)
这与你之前尝试做的完全不同。现在,您似乎正在尝试直接解析JSON文件,您现在应该在其中引用http://threejs.org/examples/#webgl_morphtargets_horse
我在这个脚本中看到了很多问题。您应该参考该链接的源代码,因为那里没有太多,而且非常直接。
我之前与您分享的街区不会自行运作。这只是一个如何填充geometry.morphTargets的例子,你还有其他事情要做,比如设置MorphAnimation类(链接的源代码演示)
