问题描述
我已经使用第3面和第3个js创建了一个网格.但是所需的颜色不会在网格上反射.这是我使用的代码.
I have created a mesh using face 3 and three js. But the desired colour is not reflecting on the mesh. Here is the code used by me.
var geometry = new THREE.Geometry();
var f = 0;
for (var i = 0; i < data.real.length; i++, f += 4) {
var o2 = i == data.real.length - 1 ? 0 : i + 1;
var tl = data.real[i];
var tr = data.real[o2];
var bl = data.zeroAxis[i];
var br = data.zeroAxis[o2];
geometry.vertices.push(tl, tr, br, bl);
geometry.faces.push(new THREE.Face3(f, f + 1, f + 2));
face.materials = [ new THREE.MeshBasicMaterial( { color: Math.random() * 0xffffff } ) ];
geometry.faces.push(new THREE.Face3(f, f + 3, f + 2));
}
var material = new THREE.MeshPhongMaterial({
color : new THREE.Color(0x008000),
side : THREE.DoubleSide,
transparent : true,
opacity : 0.5
});
var object = new THREE.Mesh(geometry, material);
object.position.set(0, 0, 0);
this.plot = object;
this.tb.scene.add(object);
this.tb.render();
推荐答案
感谢您的答复,我使用以下代码解决了上述问题.
Thanks for the reply, I resolved the above problem using the following code.
var normal = new THREE.Vector3(0, 1, 0); // optional
var color = new THREE.Color(color); // optional
var materialIndex = 0; // optional
geometry.faces.push(new THREE.Face3(f, f + 1, f + 2, normal, color,
materialIndex));
geometry.faces.push(new THREE.Face3(f, f + 2, f + 3, normal, color,
materialIndex));
请提出改进建议.
