C++ (Cpp) generateEmptyUsageBits Examples

Example #1

File: lltextureatlas.cpp Project: OS-Development/VW.Kirsten

//**************************************************************************************************************
LLTextureAtlas::LLTextureAtlas(U8 ncomponents, S16 atlas_dim) : 
    LLViewerTexture(atlas_dim * sSlotSize, atlas_dim * sSlotSize, ncomponents, TRUE),
	mAtlasDim(atlas_dim),
	mNumSlotsReserved(0),
	mMaxSlotsInAtlas(atlas_dim * atlas_dim)
{
	generateEmptyUsageBits() ;

	//generate an empty texture
	generateGLTexture() ;
	LLPointer<LLImageRaw> image_raw = new LLImageRaw(mFullWidth, mFullHeight, mComponents);
	createGLTexture(0, image_raw, 0);
	image_raw = NULL;
}

Example #2

File: lltextureatlas.cpp Project: AlexRa/Kirstens-clone

//**************************************************************************************************************
LLTextureAtlas::LLTextureAtlas(U8 ncomponents, S16 atlas_dim) : LLImageGL(),
	mAtlasDim(atlas_dim)

	setComponents(ncomponents) ;

	mCanAddToAtlas = FALSE ;//do not add one atlas to another.
	mNumSlotsReserved = 0 ;
	mMaxSlotsInAtlas = mAtlasDim * mAtlasDim ;

	generateEmptyUsageBits() ;

	//generate an empty texture
	S32 dim = mAtlasDim * sSlotSize ; //number of pixels per dimension 
	LLPointer<LLImageRaw> image_raw = new LLImageRaw(dim, dim, getComponents());
	createGLTexture(0, image_raw, 0);
	image_raw = NULL;
	dontDiscard();
