Display 25000 lines at 60FPS in THREEJS

I display 25000 lines in THREEJS and the performance is pretty poor. (<5FPS) I follow the "simplest" approach by creating 1 mesh per line and adding it to the scene: // trks is an array that contains 25000 geometries var trks = ...; var…

Extrude Buffer Geometry in Three.js?

I recently went back through a scene, replacing all the creations of new THREE.SphereGeometry() with buffer geometries: new THREE.SphereBufferGeometry() (cylinder, circle, box, etc.) down the line for all my geometries. Hit a snag creating new…

Render Order of BufferGeometry in Thee.js

Following the previous question, I'm dealing with building models in BufferGeometry, and realize that the transparent flag affects the render order: objects with transparent materials will be rendered after non-transparent ones. Also, I read from…

Animated buffergeometry with morphattributes not updating shadow

I have converted the MD2 code from the library to use THREE.BufferGeometry instead of THREE.Geometry to vastly improve memory footprint. To do this I just convert the model to THREE.BufferGeometry after it is done loading. I also had to modify the…

three.js point clouds, BufferGeometry and incorrect transparency

The problem: I have a point cloud with quite a lot of data points (around one million). When I apply transparency to the rendered points, the transparency somehow does not show what is behind the rendered points As you can see in the example of the…

BufferGeometry indices issue

I'm trying to port some code that I made in openFrameworks into THREE.JS. The code generates a landscape using perlin noise. I made it so that first a static index array is created, and then the positions of the vertices are placed out in a square…
