Nice looking lines [OpenGL]

[arthurprs]

how can i render lines like those? It's bloom or glow?

i'm trying to these effects on some weapons with that projectile

What kind of line effect are you looking for? That image is a little too low resolution to make anything useful out and it has many different kinds of lines.

sorry for the low res ops: ,

I'm looking for these "nice looking lines" like on the screens above (no edges and nice colors)

high res examples, of game Grid Wars
(thumbs, click to see full image)

Each line there is a textured quad in my opinion. Glow in objects is rendered on top of them with a blended particle. Part of the grid in first picture may be only GL_LINES. In OpenGL there is command to make anti-aliased lines but it wouldn't cover all that graphics, besides quad may be faster to render than line.

What seems you are looking for is called "particle system", litle rectangles with textures like in your example glow.bmp and rendered with blended and additive atributes; it is used for a produce a lot different effects like flames, explosions, ray guns shots, snow, etc.
