CS184 C++ Raytracer
We were tasked with creating a raytracer. Images are followed by the command line which produced them, as well as the scene file describing the setup. All times were calculated using the linux time program. All images on this page were output using my raytracer.
Three spheres and a Triangle
| Command: | ./raytrace scenes/spherestri.scene |
| Time: | 6.030s |
| Features: | Reflections, Shadows, Phong Shading, Antialiasing |
| Comments: | This photo was inspired by the Raytracing Implementation Journal. It shows off shadows quite well |
| Scene File | spherestri.scene |
Five spheres with Reflection
| Command: | ./raytrace scenes/reflections.scene |
| Time: | 7.714s |
| Features: | Reflections, Shadows, Phong Shading, Antialiasing |
| Comments: | This photo was inspired by the Raytracing Implementation Journal |
| Scene File | reflections.scene |
Three Ellipsoids
| Command: | ./raytrace scenes/mirrors.scene |
| Time: | 32.797s |
| Features: | Linear Transformations, Reflections, Shadows |
| Comments: | |
| Scene File | mirrors.scene |
Five Ellipsoids
| Command: | ./raytrace scenes/elipse.scene |
| Time: | 11.506s |
| Features: | Linear Transformations, Reflections, Shadows |
| Comments: | This photo was inspired by the Raytracing Implementation Journal |
| Scene File | elipse.scene |
Antialiasing
| Resolution | Time | Image |
| 1 | 0.354s |
|
| 2 | 1.067s |
|
| 3 | 2.305s |
|
| 4 | 4.008s |
|
| 5 | 6.093s |
|
| Command: | ./raytrace scenes/antialias.scene |
| Features: | Antialiasing |
| Comments: | The number of rays sent out per pixel is the resolution value squared. As we can see in the first image, we apply a small amount of jitter to each ray, whih further reduces aliasing. |
| Scene File | antialias.scene |
Rendering .obj
| Time: | 5m45.038s |
| Command: | ./raytrace scenes/teapot.scene |
| Features: | Loading and rendering .obj files |
| Comments: | My .obj parser does not support vector normals |
| Scene File | teapot.scene |
Angel
| Time: | 66m38.493s |
| Command: | ./raytrace scenes/angel.scene |
| Comments: | Rendering this file is pretty slow without acceleration structures |
| Scene File | angel.scene |
