You can draw points by using GL_POINTS mode if you're running OpenGL ES 1.0 or 1.1, with 2.0+ you need to perform some trickery in order to draw points

Apparantly 2.0 supports point sprites too(see comments below), so the simplest answer is to use point sprites

You can either draw circles formed from triangles or quads that are textured with circles

Drawing points doesn't differiate in any way from drawing any other shapes, you should just use different drawing mode assuming you're using fixed pipeline, or draw points by drawing cirlces or textured quads
