The program allows the user to navigate
through the scene
●
Controls:
●
Keyboard W, A, S, D to move around on XZ
plane
●
Keyboard Q, Z to move up/down in Y axis
●
Keyboard Spacebar to iterate through VPLs
●
Mouse left button drag to rotate the camera

This code is the skeleton code, which is not
fully functional
●
The program does:
●
Generate rays to generate VPLs
●
Renders the scene lit by each VPL
●
The program does not:
●
Normalize each VPL’s contribution
●
Accumulate the lightings by VPLs
●
Generate any shadows
