Real-Time Linear Wall Washer & Grazer Simulator

Stop guessing optical reach on high-rise facades. Simulate vertical illuminance ($E_v$) on textured architectural surfaces from $10\text{ m}$ heights down to base level. Test asymmetric grazing optics ($10^\circ \times 30^\circ$, $15^\circ \times 65^\circ$), fine-tune setback distances, and analyze live DIALux false-color heatmaps—all inside your browser.

I built this lightweight simulator as a fun, interactive playground for beginners and clients to experiment with lighting concepts before diving into heavy DIALux calculations. Drag lights, adjust luminous efficacy, see solid-wall occlusion in action, and get instant lux feedback—complete with one-click PDF reports to guide your final engineering plans.
