Will WebGL ever render points as circles?

Question

On desktop OpenGL, points will sometimes be rendered as circles (if you have set gl_PointSize in the vertex shader). I am tinkering with WebGL and it seems to consistently render points as squares (when gl_PointSize is set). Is there a way to get them to render as circles?

Answer 1

Yes, there is a solution. You can do that using point sprites. Just send texture to shader and using alpha blending cut of unnecessary part of sprite.

Normally (in desktop OpenGL) you may see points rendered as circles when you have got MSAA and POINT_SMOOTH feature enabled.

Below you have links where you can get all informations you need :)
