Member Function Documentation

bool LightMapManT::Allocate	(	unsigned int	SizeS,
		unsigned int	SizeT,
		unsigned long &	BitmapNr,
		unsigned int &	PosS,
		unsigned int &	PosT
	)

Finds a position for a rectangular lightmap within LightMaps[LightMaps.Size()-1].Data.

If no such position exists, a new, empty LightMapT is created and appended to the LightMaps. Returns true on success, false on failure (i.e. if SizeS>MAX_SIZE_S || SizeT>MAX_SIZE_T).

void LightMapManT::InitTextures	(	const float	Gamma,
		const int	AmbientR,
		const int	AmbientG,
		const int	AmbientB
	)

Initializes the MatSys textures in the Textures and Textures2 arrays.

Gamma correction by value Gamma is applied to the textures in Textures, but not in Textures2.
