UV construction algorithm for mesh

likwifi

Hi, I'm trying to construct UV array based on vertex points however code like this shows image completely messed.

let uvs= new Array(vertices.length);
for (let i=0;i<vertices.length;i+=2) {
    uvs[i]=vertices[i]/boundingBoxDx;
    uvs[i+1]=vertices[i+1]/boundingBoxDy;
}

Can you please suggest the way that uvs needs to be constructed.

Best.

Note that UVs are provided by MeshAttachment.

UVs are floats in the range of 0-1, a pair for each vertex. I'm not sure exactly what you are doing, but you probably need something like:

boundingBoxDx = boundingBoxMaxX - boundingBoxMinX;
boundingBoxDy = boundingBoxMaxY - boundingBoxMinY;
for (let i=0;i<vertices.length;i+=2) {
    uvs[i] = (vertices[i] - boundingBoxMinX) / boundingBoxDx;
    uvs[i+1] = (vertices[i+1] - boundingBoxMinY) / boundingBoxDy;
}
