Let's say I have a sprite, drawn like this:
spriteBatch.Draw(levelCannons[i].texture, levelCannons[i].position, null, alpha, levelCannons[i].rotation, Vector2.Zero, scale, SpriteEffects.None, 0);
Picture levelCannon as being a laser beam that goes across the entire screen. I need to see if my 3d model intersects with the screen space inhabited by the sprite. I managed to dig up Viewport.Unproject, but that seems to only be useful when dealing with a single point in 2d space, rather than an area. What can I do in my case?
