Prepares WebGL for rendering
render
()
Renders the objects and lights in the scene to the canvas element
renderLightsAndShadows
()

renderObject
-
array -
i
Renders a single object
Parameters:
-
arrayArray -
iNumberIndex in the given array
renderObjects
()
Renders the objects in the scene to the canvas element. This should not be called if the render function is being called. This is simply here so each part of the scene can be rendered separately if needed
renderShadowObjects
()
