我正在尝试正确映射 UV 纹理，但失败了...

我的应用程序中有下一个结果:

结果不是我在等待。我想要下一个描述的 View :

您需要查看 PlaneGeometry.js 并了解 UV 的设置方式。然后您将能够弄清楚如何重置它们。这应该可行——每个“面”有两个三 Angular 形。

for(var i = 0; i < geometry.faces.length / 2; i++) {

    geometry.faceVertexUvs[ 0 ].push(
    [
        new THREE.Vector2( 0, 0 ),
        new THREE.Vector2( 0, 1 ),
        new THREE.Vector2( 1, 0 ),    
    ] );

    geometry.faces[ 2 * i ].materialIndex = i;

    geometry.faceVertexUvs[ 0 ].push(
    [
        new THREE.Vector2( 0, 1 ),
        new THREE.Vector2( 1, 1 ),
        new THREE.Vector2( 1, 0 ),    
    ] );

    geometry.faces[ 2 * i + 1 ].materialIndex = i;

    materials.push( createTexture( i ) );

}    

//geometry.computeFaceNormals(); // not needed
//geometry.dynamic = true; // not needed
//geometry.uvsNeedUpdate = true; // not needed since plane has not been rendered yet
