This is a program that simulates individual rays of light that reflect and refract off of objects in the scene.
It uses my graphics and GUI library, however I have not utilised much of GUI aspect.
I am planning on implementing menus for adding objects to the scene and changing their properties, but have not got round to doing this yet.
So at the moment, there are 4 objects in the scene which can be randomly changed.
I got my inspiration for this project from some youtube video, and thought it would be a interesting project to work on.
Another main reason I worked on this was to help visualise lenses and image casting, but so far I have not managed to implement a lens object.
Originally it used a bitmap to cast the rays, but I replaced this with a geometric implementation as it allowed for more accuracy and finer detail, and I found that the performance cost was not that much.
There is a demo video on youtube of an older version.
The control scheme:
Esc - Close program;
C - Reset view;
R - Regenerate random objects;
B - Add or remove bounds;
S - Make laser automatically spin;
H - Histogram rendering;
Space - Laser points to mouse;
Middle Mouse - Pan view;
Scroll - Zoom;
Ctrl Scroll - Change laser length;
