In computer graphics, ray tracing is a rendering technique for generating an image by tracing the path of light as pixels in an image plane and simulating the effects of its encounters with virtual objects. (from Wikipedia)
In this serial, I'll share my experiences while developing an Advanced Ray Tracer.
Sections:
-
Basic Ray Tracer includes diffuse shading, specular (Blinn-Phong) shading, and ambient shading
-
Reflection and Refraction with Ray Tracer Acceleration includes reflection and refraction shadings with Fresnel coefficient, Snell's and Beer's laws. In addition, ray tracer is accelerated via Bounding Volume Hierarchy (BVH) algorithm.
-
Transformations, Instancing, Multisampling and Distribution Ray Tracing includes the experiences of implementing object transformations, instancing, multisampling and distribution ray tracing. The depth of field, Glossy reflections (imperfect mirrors) and translation motion blur is added to our ray tracing model.
-
Texture Mapping, Perlin Noise, Normal and Bump Mapping includes the experiences of implementing the Texture Mapping, Normal and Bump Mapping. Smooth shading, Perlin Noise texture and Perlin Bump mapping is also implemented in this section.
-
HDR Imaging and Advanced Lighting includes the experiences of implementing the Advanced Lighting and HDR Imaging support.
-
BRDF with Phong, Blinn-Phong and Torrance-Sparrow Reflections includes the experiences of implementing the BRDF with Phong, Blinn-Phong and Torrance-Sparrow Reflections.
-
Direct Lighting and Path Tracing includes the experiences of implementing the Direct Lighting and Path Tracing.
-
Term Project includes the Glass of Water scene by aXel.
