poly strips

[Kitty Hello]

OK, next update will feature the command POLYNEWSTRIP and you can use STARTPOLY id, 2 to start drawing triangle strips.

That way you can draw individual quads as well as long quad strips quickly. The advantage is, when you have a tile base game, you can draw a full line in one piece and then only have to specify 2 vertices per quad!!
Then you start a new strip (internally just repeats the last and the next new point) to draw a degenerated triangle (not visible) and start drawing the next line.

I'll try it in my Wumbo and see if finally I can display the background.

Also, this is a great opportunuty to draw thse glowy lines, since they are triangle strips, too.

[edit]
Update is online. Seems really a bit faster.

Oo, I like the sounds of this for my latest game. Anything to gain a few precious FPS 

I'm being a bit think (again). Could you whip up a tiny example of how this works please?

[doimus]

Yes, an example for the dumber of us, please.   

[codegit]

Yes, please, a small example will be good. (for us lesser gifted programmers)

Cool, a real nice oldskool (but still very relevant) way of speeding up GL!

Love the new command, make things for us mere mortals easy to work with

IÃ,´m now drawing my game scroll using only one startpoly/endpoly for drawing all the tiles on the screen.
Should POLYNEWSTRIP be faster than my implementation?
I thought that drawing as much triangles as posible in just one call was the fastest way but IÃ,´m not sure after reading this post.

I would like to try POLYNEWSTRIP but I donÃ,´t totally get how to implement it for scrolling.
Could anyone post an extended example?

with a strip you can draw a tile line in one batch:

Code (glbasic) Select Expand


1-3-5-7
|/|/|/|
2-4-6-8

see - 4 quads, 8 nodes.
Then you can you the "new group" and start a seperate strip.
