According to embodiments of the invention ray-primitive intersection tests in may be executed in an order according to a most recently hit primitive list. Furthermore, by pre-fetching a texture which is applied to the first intersected primitive in the most recently hit primitive list, the amount of time necessary to determine the color of the primitive based on the color of the pre-fetched texture at the point a ray intersects the primitive may be reduced. The color of the primitive due to the pre-fetched texture may be used to determine the color of a pixel through which a ray passed, and the pixel may be used to render a two dimensional image from a three dimensional scene. Therefore, by reducing the amount of time to determine the color of the pixel, the amount of time necessary to render a two dimensional image form a three dimensional scene may be reduced.
