An efficient illumination framework for web-based lighting engineering education

Although the interactive web-based learning environment enriches the study of lighting engineering, it relies healthy on realistic rendering and illumination calculations of 3D scenes. These operations are typically very expensive in kernel computations and content distribution. Hence, they are not applicable to dynamic scene. Our objective in this work is to address this problem through a multi-resolution approach in order to provide a real-time feedback to the students as they modify the lighting conditions or the geometry of the scene. We apply progressive and selective data transfer of 3D models with geometry and illumination attributes. The experimental results show that the proposed solution provides better user experience to the students.
