I don't doubt there is a feature in the engine to enable it, but because the current hardware is too weak there is no commercial game that uses it as a method to make the game appear on the monitor. The usual method for that is "rasterization", the 3D models are processed through various matrixes to determine how they look on a 2D screen. On the other hand "raytracing" means every dot (at best every pixel) on the screen shoots a ray of light into the scene and the engine follows it through several reflections/refractions (the more the better the result and the more power needed) to determine the colour of each dot on the screen.
A similar method that is used in todays games is "ray casting"- based on perspective and viewing angle rays are casted into the scene, but these aren't "traced" along the path they take after hitting the first object, so their colour information is not accurate. It's just a method to determine what is visible to the player in a scene. |
Ohhh okay good explanation Im sure the engine im using can't use it to that degree yet.
