Supported options of the .rt file

Here is an example of a config file for a scene:

A 0.2							255,255,255

C 0,0,-10		0,0,1			80

L 0,0.1,1.0		0.8				255,255,255

sp 0,5,7		5				255,0,0 
sp 1.5,1,3		2				255,0,255 
sp -6,6,5		6				255,255,0 

pl 0,0,10		0,0,1			0,255,255 
pl 0,-1,0		0,1,0			255,0,255 

cy -2,2,5		1,1,0	2	4	255,228,196

The parameters are the following:

• A intensity rgb - Ambient lighting
• C position orientation focal - Camera
• L position intensity color - Spotlight
• sp position diameter color - A sphere
• pl position orientation color - A plane
• cy position orientation diameter height color - A cylinder
