		<abstract>On-patient medical data visualization is desirable in several situations such as surgical planning and training. Currently, it becomes possible with the augmented reality, a technology which enables the visualization of the patients virtual anatomy at the location of the real one in a conventional display. In this work, we present a markerless augmented reality environment for on-patient medical data visualization, which supports: photorealism, advanced methods for real and virtual data composition and additional features such as occlusion. From an evaluation of the proposed environment, the results obtained highlight that it runs in real-time and provides good visual quality for the augmented scene.</abstract>
