2D perspective correct texturing ?

[SesillaAndromeda]

Hi phibermon,

with this code:

glBegin(GL_QUADS);
        
glTexCoord2f(0, 0);

glVertex2f  (500, 200);

glTexCoord2f(0, 1);
glVertex2f  (600,  200);

glTexCoord2f(1, 1);
glVertex2f  (1000,  700);

glTexCoord2f(1, 0);
glVertex2f  (50, 700);

this is the rendering:



Browsing the web i found the Opengl glTexCoord4f function, but it is not clear about use it.

Thanks
Sesilla
