In this paper, a novel approach for real-time heatmap generation and visualization of 3D gaze data is presented. By projecting the gaze into the scene and considering occlusions from the observer's view, to our knowledge, for the first time a correct visualization of the actual scene perception in 3D environments is provided. Based on a graphics-centric approach utilizing the graphics pipeline, shaders and several optimization techniques, heatmap rendering is fast enough for an interactive online and offline gaze analysis of thousands of gaze samples.
