Phong BRDF Modeli ile Gerçek Zamanlı Işıklandırma

Bu makalede, görüntü tabanlı ışıklandırma altında izotropik İki Yönlü Yansıma Dağılım Fonksiyonları (BRDFs) oluşturmak için gerçek zamanlı yeni bir BRDF ışıklandırma ara yüzü önermekteyiz. Önerdiğimiz BRDF ışıklandırma arayüzü kullanıcıların Phong BRDF modelinin parametrelerini değiştirerek yeni BRDF’ler oluşturmasına müsaade etmektedir. BRDF ışıklandırma arayüzümüzün implementasyonu Shadertoy aracılığıyla programlanabilir grafik donanımından faydalanmaktadır ve çevresel ışıklandırma altında bir objenin üzerinde malzemenin gerçek zamanlı olarak gösterimini sağlamaktadır.

Real-Time Shading with Phong BRDF Model

In this paper, we propose a novel real-time Bidirectional Reflectance Distribution Function (BRDF) shading interface for creating isotropic BRDFs in image-based lighting. Our proposed BRDF shading interface allows users to generate new BRDFs by tweaking parameters of underlying BRDF model, which is Phong BRDF model. The implementation of our BRDF shading interface utilizes programmable graphics hardware through Shadertoy, and it provides a real-time visualization of the material on an object in environment lighting.
