The sole purpose of this project is to visualize my first raytracer from scratch in a better prespective using a engine.
When in the game view (IN PLAYMODE) of the project press space to view the hit positions on the sphere & they should be displayed in the scene view.
This was not made with a high focus on optimization but just optimized decently.
You can also click the raytracer object in playmode & view the script attached to it. You can change many things such as the radius of the sphere, show rays, show hit positions, change alpha of rays that hit nothing & etc.
Project made in Unity > BIRP > Version 2021.3.16f1
Here are all the parameters you can control, explanation is below the image.
- Width & Height resemble the density of rays & is essentially just resolution (Aspect ratio taken into account).
- Length is just simply the magnitude of the ray.
- Radius is the radius of the sphere to raytrace (the white gizmo sphere).
- Forward offset to move the ray origin on the Z axis.
- Main Light can be anything but just takes its direction its pointing @ to calculate shading.
- Root 0 Alpha is the color alpha of the rays not hitting the sphere 0 is nothing/transparent 1 is max/opaque.
- The next 3 bools are to show rays, show the hit positions as gizmos, & showing the position of the raytraced sphere as a gizmo.
- Reload Gizmos Key, Press the reload key to see gizmo hit positions, & always keep pressing it when changing values.
- Finally, just gizmo sphere size.
The last 4 lists all dont need to be tampered with & are there for debugging purposes.
I also don't know of a method to draw gizmos in the update method if you know a good method tell me about it.
I never found a "good way" of drawing gizmos dynamically (i did have a dynamic method but it was very laggy when increasing radius because of the # of gizmos that would need to be drawn on the screen.) so if you have a better method maybe do a pull req or tell me about it, thanks.
Here are some gif & images below to see the project without downloading.
