Init() Set scene parameters like width, height Configure camera. Set values like view angle, aspect ratio, etc Check for WebGL renderer Initialize mouse controls and set lighting conditions Initialize statistics control panel Add all of the parameters to the already initialized scene

variable

Animate() render()

reload scene and camera with the current control inputs update()

update controls and statistics to reflect the latest state Animate()
