GL_POINT_SPRITES on Mobile Intel(R) 945 Express Chipset Family Texturing problem

GL_POINT_SPRITES on Mobile Intel(R) 945 Express Chipset Family Texturing problem

Hi there, i am trying to make my GL_POINT_SPRITES textured when i add a texture to them they all look like a first pixel of a texture in the image below its yellow:

 

 

but i alos tried it on a different computer with geforce and it lloks like it should:

since i see that my card can support point sprites i wonder why i cant make this texture be drawn right.

 

heres the code:

	glEnable(GL_TEXTURE_2D);

		glBindTexture(GL_TEXTURE_2D, m_texStar);
			 glTexEnvi(GL_POINT_SPRITE, GL_COORD_REPLACE, GL_TRUE);
	  glEnable(GL_POINT_SPRITE);

  glPointParameterf(GL_POINT_SIZE_MAX, 35.0f);
  glPointParameterf(GL_POINT_SIZE_MIN, 1.0f);

  glPointSize(maxSize); 
  glBegin(GL_POINTS);

		   glVertex3f(pos.x,pos.y,0);

  glEnd();

	 glDisable(GL_POINT_SPRITE);
  glDisable(GL_TEXTURE_2D);

 

 

any idea what i should add to make it work, or this old graphics can't render it, how couldi check such thing then?

 

Cheers

Hi Cezary,

 

I am afraid there is not much we can do to help. Point Sprites are supported on the Mobile Intel(R) 945 Express Chipset Family. However there is a bug in the driver and no fix is available as the product and driver are EOL.
