What is the correct way to edit the vertices of the window geometry?
So, I edit the vertices of many box geometries to create unique shapes or to change the heights of the geometries. It works great and my scenes look correct (here's an example http://imgur.com/sSx1bPk ).
However, when I use ObjectExporter
and try to load the scene at http://threejs.org/editor/ , none of my vertex changes.Also when I try to load the file scene.json
in blender I get an error (which I cannot copy / insert), which listsKeyError:'vertices'
Basically, I created a UI to edit the vertices of any window geometry, I save these changes to a matrix and then cross-check that matrix when the scene loads. My function looks like this:
setBaseTileVertices:function()
{
var scope = this;
scope.baseTiles.children.forEach(function(tile , t)
{
tile.geometry.vertices.forEach(function(vertex , v)
{
vertex.x = (tile.userData.vertices[v].x) ? tile.userData.vertices[v].x : vertex.x;
vertex.y = (tile.userData.vertices[v].y) ? tile.userData.vertices[v].y : vertex.y;
vertex.z = (tile.userData.vertices[v].z) ? tile.userData.vertices[v].z : vertex.z;
});
});
}
Is there another more correct way to edit vertices so that the changes are recognized by the editor and / or Blender? Am I using the correct exporter? I tried to use THREE.SceneExporter
but got errors as pointed out here Three.js SceneExporter getting "Disable syntax" error
Edit
After doing a little research, I saw that in my JSON issue, all of my box geometries have the same matrix value, and the square pyramid I created has the correct matrix. I think I need to update the matrix of each geometry when I modify it. Not too sure how to do this right now, but I think I am on the right track.
Edit 2
Well, it looks like the matrices for each of my geometries are updating, so I don't know what's going on now. The pyramid I created renders perfectly, but all the window geometries just flatten without changing their vertices. Here's an example of what it looks like in the editor http://imgur.com/oGury4e , notes that the bounding box helper knows the height baseTiles
, which is Object3D
which each chunk contains. He can only know this if he factorizes their edited vertices.
Edit 3
So I followed the test and modified lines 65 - 74 of ObjectExporter.js
so that they now read
} else if ( geometry instanceof THREE.BoxGeometry ) {
data.type = 'Geometry';
data.data = geometryExporter.parse( geometry );
delete data.data.metadata;
//handleParameters( [ 'width', 'height', 'depth', 'widthSegments', 'heightSegments', 'depthSegments' ] );}
Now my level looks correct in terms of the form in the editor http://imgur.com/IDlYCJ6 , however my colors or materials don't seem to be translated? Everything is black, while the + Y-faces of the geometry should be colored green.
As per the example requested here for exporting with an unreleased ObjectExporter

Any ideas?

After some research, I found that currently the correct way to do this is to convert objects BoxGeometry
to BufferGeometry
or regular Geometry
objects. You can do this after editing your vertices.
So something like this
var box = new THREE.BoxGeometry(64 , 32 , 64);
box.verticesNeedUpdate = true;
box.vertices[0].y = 128;
box.vertices[1].y = 128;
var geometry = new THREE.BufferGeometry().fromGeometry(box);
//or alternatively
var geometry = new THREE.Geometry();
geometry.merge(box);
Now if you export an object using ObjectExporter
, it should upload fine at http://threejs.org/editor .
