After a long time, I revisited my three.js project and was reminded of the days when I used to type out the full name PlaneBufferGeometry. The project features several vehicles that are supposed to reflect their environment (and each other) through the use of CubeCameras. However, upon activating this feature, I encountered the following error:
Uncaught TypeError: Cannot read properties of undefined (reading 'up')
at CubeCamera.updateCoordinateSystem (three.module.js:12739:13)
at CubeCamera.update (three.module.js:12803:9)
at CLASS_drone.update (blend.levels.php:2960:19)
Here is what is happening in the context of CLASS_drone:
function CLASS_drone(x,y,z,path,pts)
{
this.x = x;
this.y = y+0.25;
this.z = z;
this.path = path;
this.ptstart = pts;
this.pts = pts;
this.drone = new THREE.Group();
this.body = drone.clone();
this.bidx = 0;
this.widx = 0;
this.fps = 0;
...
And here is how I include three.js in the project:
<script type="importmap">
{
"imports":
{
"three": "https://threejs.org/build/three.module.js",
"OBJLoader": "https://threejs.org/examples/jsm/loaders/OBJLoader.js"
}
}
</script>
