A curated collection of interactive optics tools, technical notes, and learning references to support optical reasoning and intuition.
Interactive Optics Tools
Interactive tools designed to support geometric understanding and physical intuition in optics.
RaySight — Introduction
RaySight is an interactive optics tool designed to support the development of optical intuition.
Rather than focusing on numerical optimization or detailed simulation, RaySight emphasizes early-stage reasoning—helping users explore ray behavior, boundary conditions, and energy redistribution through direct manipulation.
It is intended for optics students, engineers, and educators who wish to strengthen conceptual understanding and build reliable mental models before engaging in full-scale optical design workflows.

RaySight v1.1
An interactive optics tool focused on intuition-building. It emphasizes reasoning and physical understanding rather than numerical optimization.
RaySight - A White Paper on Building Optical Intuition
Design philosophy and reasoning for interactive optics learning. Includes governing equations in Appendix A.
Version history
2026/01/13 -- RaySight v1.0 — Initial public release focused on refraction, reflection, and Fresnel behavior at a single interface.
2026/01/14 -- RaySight v1.1 — Added converging fan rays to enable visualization of ray convergence and incorrect-side (wrong-side) ray filtering.Â
Solid Angle Visualizer (3D)
Solid Angle Visualizer is an interactive 3D tool designed to help you build intuition for solid angle and angular coverage.
Rather than treating Ω as a formula alone, it emphasizes visual reasoning—letting users manipulate angular bounds and immediately see the corresponding region on a hemisphere, along with Ω in steradians and coverage fraction.
It is intended for optics students, engineers, and educators who want reliable mental models for field-of-view, apertures, and source–detector geometry before moving into full radiometric workflows.
Solid Angle Visualizer (3D)Â
An interactive 3D tool focused on intuition-building for solid angle and angular coverage. It emphasizes spatial reasoning and physical understanding rather than formula memorization or heavy simulation.
A White Paper on Building Solid-Angle Intuition
Design philosophy and reasoning for interactive 3D learning of solid angle and angular coverage. Includes governing equations in Appendix A.
Version history
2026/01/29 -- v1.0 — Initial public release featuring interactive θ–φ bound selection and real-time Ω readout.
