| Task 1:
|
| Some simple raycasting to determine the intersection between the rays and the spheres.
|
| Task 2:
|
| These are the spheres including diffuse lighting (phong-style).
|
| Task 3:
|
| These are the spheres including diffuse and ambient and specular lighting (phong-style).
|
| Task 4:
|
| And now some shadows.
|
| Task 5:
|
| More lightsources and colors and more shadows.
|
| Task 6:
|
| Added antialiasing (not really that visible on the thumbnail) and refraction.
|
| Task 7:
|
| Now the task was to implement a few more objects other than spheres, so here is a picture of my cylinders.
|
| EPF Lenses:
|
| At this point I decided to integrate EPF lenses into my raytracer just to see how I could warp the rays with it. Here is a simple zoom-out example.
|
| A Manhattan Lens created an inset into the picture.
|
| Another lens for which I can't remember the parameters I used (I assume it's a round lens with Gaussian drop-off.
