标签: texture-wrapping

我搜索在模型上重复纹理.在所有的例子或问题上,我发现只有这样:

var lavaTexture = THREE.ImageUtils.loadTexture( 'images/lava.jpg' );
lavaTexture.wrapS = lavaTexture.wrapT = THREE.RepeatWrapping;
lavaTexture.repeat.set( 3, 3 );
var lavaMaterial = new THREE.MeshBasicMaterial( { map: lavaTexture } );

我理解这一点,但是当材料写成这样:

Wood: new THREE.MeshPhongMaterial( {
   color: 0xffffff,
   specular:0xffffff,
   shininess: 10,
   map: new THREE.ImageUtils.loadTexture ( "models/macabann/chataigner.jpg"),
// not sure as right
   WrapS : THREE.RepeatWrapping,
   WrapT : THREE.RepeatWrapping,
   maprepeat : [2,2],

   envMap: textureCube,
   combine: THREE.MixOperation,
   reflectivity: 0.05
} )

如果可能的话,我会搜索如何以这种格式写出这个.谢谢你的回答.

我没有在openCV中找到任何在java中将平面图像转换为圆柱形的示例,我希望它在2d而不是3d中渲染图像,也没有找到任何示例代码或书籍.下面是我想在杯子周围扭曲的图片的图像.

一本好书和示例代码将非常感激.

到目前为止我已经这样做了.建议我的@Amitay使图像凹陷,使用此示例将图像包裹在圆柱体周围但卡在转换上.
