Use of high dynamic range images for improved medical simulations

Here we describe the use of high-dynamic range lighting techniques to improve the rendering quality of real-time medical simulation systems. Specifically we show our method of extracting the lighting information from an actual endoscopic light probe used for surgery and how we apply this lighting information into a real-time rendering system based on OpenGL and using Shaders to improve the realism of the probe's lighting in the scene; with the consideration that it is the only light source in the simulation
