Web11 de dez. de 2024 · When there is room for interpretation, you can control certain aspects of OpenGL behavior with hints. You specify a hint with two arguments. The target parameter is a symbolic constant indicating the behavior to be controlled, and mode is another symbolic constant indicating the desired behavior. WebGL_LINE_SMOOTH_HINT. Indicates the sampling quality of antialiased lines. If a larger filter function is applied, hinting GL_NICEST can result in more pixel fragments being generated during rasterization. GL_POLYGON_SMOOTH_HINT. Indicates the sampling quality of antialiased polygons.

Anti-aliased points get rounded with respect to their radius. (I've used OpenGL since 2003, and I didn't know this. [/shame]) So enabling GL_POINT_SMOOTH while you have a multisample-able visual/pixelformat, you get rounded points. Still, multisampling can be slow, so I'd implement both. Textured quads are cheap.
