Function Documentation

encode_light()

video::SColor encode_light	(	u16	light,
		u8	emissive_light )

Encodes light of a node. The result is not the final color, but a half-baked vertex color. You have to multiply the resulting color with the node's color.

Parameters

light	the first 8 bits are day light, the last 8 bits are night light
emissive_light	amount of light the surface emits, from 0 to LIGHT_SUN.

final_color_blend() [1/2]

void final_color_blend	(	video::SColor *	result,
		const video::SColor &	data,
		const video::SColorf &	dayLight )

Gives the final SColor shown on screen.

Parameters

result	output color
data	the half-baked vertex color
dayLight	color of the sunlight

final_color_blend() [2/2]

void final_color_blend	(	video::SColor *	result,
		u16	light,
