Ray trace algorithm
WebJun 13, 2024 · Ray tracing is an effective tool for high-frequency optics simulations. The Ray Optics Module for the COMSOL Multiphysics® software uses a multiphysics-capable wavefront method for its ray tracing. In this blog post, we’ll explore what makes the ray tracing algorithm in COMSOL Multiphysics distinct from traditional ray tracing algorithms ... WebIn recent years, ray tracing has become the algorithm of choice for generating high fidelity images. Its simplicity and elegance allows one to easily model reflection, refraction and shadows.1 Unfortunately, it has a major drawback: computational expense. The prime reason for this is that the heart of ray tracing,
