Add geometry faces/vertices

Question

I got a 2D Hexagon in my init()-Code, works well. I push 6 vertices and new faces, but nothing appear. Why?

for-loop:

    b.world.grid[x][z].Model.geometry.vertices.push(new THREE.Vector3(b.world.grid[x]       [z].Model.geometry.vertices[i].x,b.world.grid[x][z].Model.geometry.vertices[i].y,b.world.grid[x]        [z].Model.geometry.vertices[i].z));

    b.world.grid[x][z].Model.geometry.faces.push(new THREE.Face3(0, 1, 7));

I already used VerticesNeedUpdate

Have you tried this code:

b.world.grid[x][y].Model.geometry.groupsNeedUpdate = true;

You need to update the group, not the vertices array, because the existing vertices haven't changed — you have just added some more, but you need to update the group of your existing model.

Save me lot of time (this is something referenced nowhere in documentation). Thanks – tigrou May 15 '15 at 22:17
