Problem with pspgl texturing

[drcd]

Hi
I would like to know if there are problems with pspgl texturing because i can draw for example a quad but when i want map it, the mapping does nothing or the quad disappear. My texture is in a tga format and works on PC. So if someone here knows problems and how to solve them,can you tell me ho to fix it?
Thx

Quads aren't supported. From the pspgl homepage http://www.goop.org/psp/gl/:

GL_QUADS
not supported

I know but:

Code: Select all

glBegin(GL_QUADS);
glVertex3f(Position.x,Position.y,Position.z);
glVertex3f(Position.x+Size.x,Position.y,Position.z);
glVertex3f(Position.x+Size.x,Position.y-Size.y,Position.z);
glVertex3f(Position.x,Position.y-Size.y,Position.z);
glEnd();

This part of code draw a quad. So i thought that the website wasn't updated.

I seem to recall someone saying that GL_QUADS are implemented with GL_TRIANGLE_STRIP.
Check if your code works with them on pc, maybe its back to front?
(Haven't played with em myself, just using triangles atm)

I've tried GL_TRIANGLE_STRIP and i have the same result. I've also tried to just draw a quand using GL_QUAD and change its color using glColor3ub but the quad kept its black color. I've tried to do the same thing with GL_TRIANGLE_STRIP and apply a color but i saw the same result (black color). It's very strange. Does someone can texture a quad or change its color?

Well, in fact there is no problem with pspgl to bind texture. I've tried with a bmp loader and it works fine but i would like to use tga or bmp with an alpha component and i don't know if it's possible.
