Hello,
I’m working in an application that has to draw some 9x9 2D markers onto some images. I thought that the best way to do that was using point sprites, without point smooth and with some blending. Well, I’ve found that this was harder than I thought. The marks are shown distorted. I dont know why but they are. I’ve found that adding 0.5f to the marks and writting them as float, they are shown fine, but I really dont think that this could be a solution rather than a workaround. I’ve managed to write a simple demo application that reproduces the issue. You can get it from here: TEST APPLICATION (VC8).
Note: In an ATI card with latest drivers all works good, in NV cards (our main developement platform) with latest drivers, is where we are having problems.
