Hello trace-masters! I’m back with another cool study!

In this post, I will share my ray tracer outputs where the scene consists of my own face mesh and an HDR spherical environment light map.

Hello trace-masters!

In this post, I will first give some information on indirect illumination in ray tracing and bidirectional path tracing algorithm, and then I will write about how I have implemented my term project, a naive version of the Bidirectional Path Tracing (BDPT) algorithm. Moreover, I will provide a comparison of my BDPT outputs with my ray tracer and path tracer outputs.

Hello trace-masters!

I am back with my last assignment, in which I have implemented:

• Object Lights
  • Mesh lights
  • Spherical (also ellipsoid) lights
  • Spherical environment lights
• Path Tracing

In this post, we will examine those topics in detail.

Hey trace-masters, Bidirectional Reflectance Distribution Functions are here! In this post, we will examine what those BRDFs are and how they are used.

Hey trace-masters, High Dynamic Range rendering is here!

In my fifth assignment, my task was to implement:

• HDR (High Dynamic Range) rendering capability, which includes
  • Exporting images as .exr files, and
  • Performing tonemapping operation to map HDR images to LDR (Low Dynamic Range), so that their approximate appearances can be shown on non-HDR screens.
• Two new light types, which are
  • Directional light
  • Spot light

In this post, we will examine them together!
