Application of ray tracing algorithm based on intersection optimization in 3D interior design

Aiming at the problem that the current algorithm of lighting effect cannot achieve a good effect in 3D interior design, this paper proposes an algorithm based on multi algorithm fusion to realize lighting effect in 3D interior design. The algorithm first optimizes the intersection of patch, sphere and rectangle based on ray tracing algorithm, and then optimizes the optimization algorithm and the algorithm of lighting shadow at the same time, it is applied to the realization of lighting effect of 3D interior design. The simulation results show that the algorithm based on multi algorithm fusion is more ideal for the realization of 3D interior design lighting effect than the existing algorithm.
