I want to start using Webgl for 2d sprites in a simple screen coordinate system.
I like to draw sprites with the following bounds e.g [x, y, w, h] (maybe z too)
sprite1.x = 500;
and not a coordinate System with floats that begin in the center of the screen.
I try to use 2d ortho projection like i used to in directX but i fail it seams like there ist no Ortho mode for webgl... Am i missing something?
What can i do to reach my goal ?
thanks for your help
