A paint-based approach for optimal lighting design in real scenes


Lighting design is a computational expensive task, commonly done using Computer-aided design (CAD) software in a virtual scene. The designer places and tunes the virtual light sources and, yet the virtual environment is ideal for physically correct light tracing, the costly simulation might not provide the desired impression in the real scene. Moreover, the chosen light placement is not necessarily optimized. In this work we capture light behavior from real scenes as well as 3D scene properties and use this information to recreate different lighting designs. The results approximates physical correctness while visualizing the illumination on the real scene in a more time-efficient way. To make the design process more intuitive, the user paints the desired light properties instead of placing the light sources. The system attempts to find valid positions and parameters of the light sources in the scene to reflect the current design. Constraints such as number of light sources and emission profiles as well as spatial constraints can also be specified.

Title: Topology Optimization of Multiscale Structures for 3D Printing

Abstract: 3D printing enables the fabrication of complex structures. In engineering the benefits of this manufacturing flexibility are probably best demonstrated in combination with the design of structures by topology optimization. In this talk I will present our research on topology optimization of multiscale structures. The first approach, inspired by trabecular bone, generates porous bone-like infill structures for 3D printing. This approach is extended to allow simultaneous optimization of shape boundaries and the interior lattice. To reduce its computational complexity, a homogenization-based approach is developed to project orthotropic lattice structures. In the second approach, we develop a continuous formulation to the discrete problem of quadtree subdivision. By restricting the subdivision level, geometric features such as maximum and minimum structure sizes can be controlled, for manufacturing benefits.

Images of optimized structures and fabrication results can be found on this page.
