Public Member Functions

 CHLSTextureBank ()
 Constructor.

Build
uint32 addColorTexture (const CHLSColorTexture &tex)
 Add a colorisable texture to the bank.

void addTextureInstance (const std::string &name, uint32 colorTextureId, const std::vector< CHLSColorDelta > &cols)
void compile ()
 compile the bank.

void reset ()
 clear the bank

void serial (NLMISC::IStream &f)
 serial. if loading, ptrs are correclty setuped => no compile() needed

Usage
void fillHandleArray (std::vector< CTextureInstanceHandle > &array)
 Append handle into the array (build of the manager).

Member Function Documentation

uint32 NL3D::CHLSTextureBank::addColorTexture (  const CHLSColorTexture &  tex  ) 
 

Add a colorisable texture to the bank.

References _ColorTextures, and uint32. 

00057 {
00058         _ColorTextures.push_back(tex);

void NL3D::CHLSTextureBank::addTextureInstance (  const std::string &  name,
uint32  colorTextureId,
const std::vector< CHLSColorDelta > &  cols
) 
 

Add an instance texture (ie colorised) to the bank

Parameters:
name name of the colored texture. NB: it is lowered in this method
colorTextureId index returned by addColorTexture()
cols must be same size of number of mask of the colorTextureId pointed (nlassert)
