Working around gl_PointSize limitations in three.js / webGL

Question

I\'m using three.js to create an interactive data visualisation. This visualisation involves rendering 68000 nodes, where each different node has a different size and color.

Answer 1

Can I do something like draw a mesh for any points larger than a certain size, but use a gl_point otherwise?

Not in WebGL.

You can draw your particle system as a series of quads (ie: two triangles). But that's about it.
