I’m trying to load an .stl file into three.js. Everything works fine and I get the model as BufferGeometry using this code: To make it easier to further manipulate the model I would like to have the geometry as regular THREE.Geometry instead of THREE.BufferGeometry. Is it possible to either load the .st…

Render objects on top using renderDepth with Three.js
I’m trying to render objects on top of other objects. In the fiddle, get the green torus knots to render on top of the red boxes and floor. I’ve been trying mesh.renderDepth = 0, 1, 1000 and changes nothing. The material has been created like so: How can I achieve this using renderDepth? Am I miss…

How to Set WebGLRender background to transparent
I’m trying to put objects in front of CSS3DObjects with the THREE.NoBlending hack. But I only see the black plane without the CSS3DObject in the newest revisions (tried r65 and r66).

Three.js – Rotating a sphere around a certain axis
I have a problem. In Three.js, I want to rotate a sphere (Earth) around axis tilted by 23.5 degs. I found sphere.rotation.x, sphere.rotation.y and sphere.rotation.z, but when I combine them in the correct ratio, the sphere’s rotation is quite weird – it has no permanent rotation axis. I think I ne…
Three.js Using 2D texturesprite for animation (planeGeometry)
I’m quite new in html5 and three.js. I’ve been experimenting a bit with it, and basically what I want done is to have a Mesh (I’m using planeGeometry, as the tutorial I followed used it). The Mesh shows different Textures, which can change later on. Here’s what my code looks like: The …
THREE.js Ray Intersect fails by adding div

As soon as I add another div with fixed height and width above the target div, ray.intersectObjects returns null. I doubt that the vector that I am creating for ray is causing the problem. Here is the…
Three.js WebGL texture shows up black on plane
So basically, I have a scene in WebGL with 2 planes. One of them has a transparent texture on it and it shows up fine. The other is supposed to have a high res, non-transparent texture loaded up on it and it is used as a background. I can’t figure out why the background plane isn’t working, since …
three.js transparent maps issue
I’m creating loads of particles (80.000 to be exact) and I have set a transparent map, though, not all particles are transparent. I’m using a transparent PNG image: (it’s barely visible but it’s there alright) as the material map, though it shows a black background as seen here: If you…
