This paper presents the initial development of a software tool with its GUI that allows analyzing the lights and shadows into the abdominal cavity during laparoscopic surgeries, when the internal lights are manipulated by lighting mini robots and have a different configuration to the regular one. The tool developed was created in the Blender environment with similar basic elements to a real laboratory, initially including the liver and gallbladder. Once obtained an environment similar to the real one, it was exported to the rendering engine Ogre 3D, where it was performed the manipulation of the environment, lights and the obtaining of 3D imaging. Finally, the tool was created with these images and using libraries for image analysis (OpenCV).
