A Solar System model with legacy opengl. Computer Graphics course assignment.
l -> Enable/Disable Lighting
t -> Enable/Disble Texture
o -> Enable/Disable drawOrbit
- -> decrease time speed
+ -> increase time speed
0 -> reset camera rotation/position
w, s -> change X axis rotation of camera around sun
a, d -> change Z axis rotation of camera around sun
left click and mouse motion-> change view angle
right click -> glut menu, to change light color, speed or texture
scroll up/down -> zoom in/out to sun (move in z axis)
Orbitals distances is life-size as AU (astronomical unit). Planets sizes also proportional.
But the sun's size a bit tricky. I could not do sun as big as in life. Because when I tried enlarging sun, other planets was absorbed by sun. Then I tried enlarge orbits with sun, but this time the planets became small and impossible to see. So, I scaled sun's size different from other distances.
Celestial bodies has elliptic orbitals like real life, and sun at one of the two focus. I preferred Icospheres to render planets.
