Ray-tracing is a computational demanding image generation technique capable of create photo-realistic images. Due to its high demand of computational power, ray-tracing is not used for realtime applications, however, with the massive parallel capabilities of current Graphics Processing Units, and the fact that ray tracing is a suitable application for parallel processing, the use of GPU based Real-Time Ray-Tracing started to be seriously considered. This work investigates a GPU only approach for rendering images, where both raster and ray-tracing strategies are used in a hybrid approach, in order to improve visual quality while maintaining an interactive or near real-time performance.
