First Unity Pathtracer v 0.8

Officially better in fullscreen

So far I only have circle intersections. 

WASD and Up and Down Arrows to move (Hold Shift to move slower). 

Hold T and Left and Right Arrows to Tilt. 

Right-click and drag to Rotate.  

Create spheres by pressing C.  Creating Spheres will create a sphere with the most recent material created

Hold Ctrl and scroll to change the focal length. 

Press Ctrl+I to bring up the debug menu / UI.

Press Ctrl + C to bring up the create menu.

Ctrl + E to bring up the edit menu (On the browser you may have to go full screen as Ctrl + E is already a keybinding for Secure Search)

Accumulate frames for less noise in the UI. Locks Movement

Huge Update: 

Fixed some issues with the random sampling of directions in diffuse reflections.

Replaced the cursor so that you can continuously scroll the mouse. (To get your regular mouse back press Q. Not Escape)

Replaced sliders with Input Fields that are draggable. You can of course type as well.

Added the Create and Edit Menus for creating and editing Spheres and Materials.

This was actually quite difficult to implement and there are still some bugs.
