I am making a 2D game similar to Age Of Empires.it is very irritating to see that OpenGL does not often draw boundary Pixels to prevent overdraw of pixels for primitives touching each other.Especially when drawing single lines or textured quads, often the boundary pixels are not drawn.
I do not want to compensate by adding or subtracting 0.5 or setting 0.375 etc in the view as is the commonly used approach in overcoming this.
IS there any simple way to override this in opengl ? Like say setting a simple state variable ? or some property of lines or polygons ?
Also while zooming i do want the blurred zooming that occurs when i try to scale in opengl.I want to zoom in as MSPAINT does when we ask it draw at say 800%.Each pixel is made bigger AND THERE IS NO BLURRING. Can i achieve the same effect in openGL ?
Do i need to post this in the Advanced FOrum?
thanks in advance for any help from anybody
