HTML5 Canvas 3D WebGL (TM) javaScript Library
 

setLighting Library Method

Signature: sc.setLighting (ena,perVertex)
Class: taccglShaderConfig Class
 

ena and perVertex must be boolean values. If ena=false the shaders do not perform any lighting calculation. If ena=true then perVertex can be used to select between lighting calculations per Vertex or per Fragment. However even if per fragment lighting is selected taccgl™ will also make an additional perVertex shader and use it if the performance requires.

Per default lighting per Fragment is enabled. If there are problems compiling shaders, lighting is disabled.
