PHYSICALLY BASED RENDERER

The purpose of this project was to create a renderer capable of showcasing the image quality that can be achieved using modern rendering techniques. I developed it mostly from scratch, over the course of a semester. In its development I used a couple of external tools mainly for loading meshes and textures into the application.

Ambient Occlusion

Notice how the spheres and the table are blocking some of the ambient light when they are in close proximity of one another. Also noticeable on the demon head's wrinkles.

Caustics Approximation

As a final project, I decided to approximate real time caustics. Not viable for real time though.

Image Based Lighting + PBR

Stanford Bunny being lit by the room around it, including some glare from the TV screen

Deferred Shading

This scene contains 15000 small colored point lights that illuminate parts of the Sponza. The demo ran at between 60 and 30 frames-per-second, depending on the amount of lights on screen.

Dual Paraboloid Shadow Maps

Shadowmap generated from one of the sides of a point light. Scene being lit is the Sponza

Exponential Shadow Maps

Output of slightly blurring the shadowmap obtained from the dual paraboloid projection.

Languages:

OpenGL 4.4
C++

Features:

Deferred Shading
- Set up a GBuffer consisting of Position, Normals, Diffuse Color, Specular Color, Ambient Color and Depth buffers.
Exponential Dual-Paraboloid Shadow mapping
- Used two shadow maps to cover the entire sphere of influence of a point light instead of the usual six.
