face

Trying to paint each cube face with a different color, I found a thread that presents a way to achieve this: var geometry = new THREE.BoxGeometry(5, 5, 5); for (var i = 0; i < geometry.faces.length; i++) { geometry.faces[i].color.setHex(Math.random() * 0xffffff); } var material = new THREE.MeshBasicMaterial({ color: 0xffffff, vertexColors: THREE.FaceColors }); But with three.js r86, I get the following result: Got the triangles that make up each face, painted individually. To achieve the desirable effect, I used the following adaptation of the above code: var geometry = new THREE.BoxGeometry(5

I´m trying to merge two geometries/meshes (red and blue) into a unique one. But after creating a new geometry and applying geometry.merge() I found that all the inner vertices and faces are still there (the green area). I would like to remove all that extra information, as it generates visual glitches on the rendered faces and also I cannot calculate the merged volume correctly.. I need something like on the last picture, a single mesh that only includes the minimal external/outer faces and vertices, removing the inner ones. I tried applying ThreeCSG to subtract meshes but I´m founding that it

I have a THREE.PlaneGeometry , with ComputeFaceNormals() . I create two meshes using this geometry, with different rotations applied to them. I want to compute the two angles between the camera and the two meshes central face normal. It should be : vLocalCamera = vCamera.position - mesh1.position; mesh1.normal() . vLocalCamera = cos(angle); The problem is that I don't know how to get the mesh normal in world coordinate (from geometry and mesh rotation) with three.js API If you want to convert a face or vertex normal, normal , from local space to world space, you do it like so: var normalMatrix

I actually found this question, but it says material.color doesn't exist. I need to know how to change the colors of the various faces of a cube I'm drawing: var newCube = new THREE.Mesh(new three.CubeGeometry(size, size, size), new three.MeshNormalMaterial({ vertexColors: three.FaceColors })); Here is how you set and change the colors of a cube's faces: var geometry = new THREE.BoxGeometry( size, size, size ); for ( var i = 0; i < geometry.faces.length; i ++ ) { geometry.faces[ i ].color.setHex( Math.random() * 0xffffff ); } var material = new THREE.MeshBasicMaterial( { color: 0xffffff,
