Inheritance diagram for NL3D::CTextureDLM:

Detailed Description

This texture is used by landscape to perform Dynamic LightMap (DLM). Actually a CTextureDLM handle many block of lightmap in one single big texture. If NL_DLM_TILE_RES, then Block can be of size of 2,3,5 or 9 * 2,3,5 or 9 (eg 2x9, or 5x5 texture). else Block can be of size of 3,5,9 or 17 * 3,5,9 or 17 (eg 3x17, or 9x9 texture).

Implementation note (NL_DLM_TILE_RES not defined): To make this possible easily, blocks of 10x10 are created and placed in the texture. Hence a 9x9 texture lies in a single block, 3 textures of 3x9 lies in a block etc... In worst case, lost space is 19% (1 - 9*9 / 10*10).

If NL_DLM_TILE_RES is defined, then, same reasoning, with blocks of 18x18. In worst case, space lost is 70%: (1 - 15*15 / 18*18). But others cases are pretty good (90% to 100%)

NB: TextureDLM ensure that point (MaxX,MaxY) of this texture is black. UseFull for patch who want default black color

void NLMISC::CBitmap::blend ( CBitmap & Bm0,

CBitmap & Bm1,

uint16 factor,

bool inputBitmapIsMutable = false

) [inherited]

Set this bitmap as the result of the blend bewteen 2 bitmap REQUIRE : - Bm0 and Bm1 should have the same size.

Both bitmap should be convertible to RGBA pixel format. The result is a RGBA bitmap. NB: this just works with the first mipmaps
Parameters:

factor The blend factor. 0 means the result is equal to Bm0, 256 means the result is equal to Bm1

inputBitmapIsMutable when true, bitmap can be converted in place when needed (no copy done)

void NL3D::ITexture::generate ( bool async = false ) [inline, inherited]

Generate the texture pixels.
This method is called by the driver when it needs to generate pixels of the texture. If the texture is used for the first time or if it is touched, the driver will call this method. For exemple, a texture file will load the bitmap in this method.
If the invalidate rect list is empty, generate() rebuild all the texture. If the invalidate rect list is not empty, generate() rebuilds only the invalidate rectangles in the list.
Don't clear the touch flag or the invalid rectangle list until updating the texture in generate(). It's the generate()'s caller jobs.
After generation, if the texture is releasable, the driver will release the texture by calling release().
NB: a flag is maintained to see if the generated bitmap is coherent with texture description (see touch*()). So if you do {generate(); generate();}, you only get 1 real bitmap generation...
If, after the doGenerate, the bitmap format is compressed (DXTC) and no mipmaps have been generated, the mipmap are disabled beacause the user probably don't want the driver to unpacks the texture, generates the mipmaps and repacks the dxtc texture (that takes a lot of CPU time).

Parameters:

async tells the texture if the call is made asynchronously or not.

Resize the bitmap. If mipmaps exist they are deleted and not rebuilt. This is not a crop. Pixels are lost after resize.

Parameters:

nNewWidth width after resize

newType is the new type of the bitmap. If don_t_know, keep the same pixel format that before.

NB: if multiple ITexture acces the same data via the sharing system (such as a CTextureFile), then:

WrapS/WrapT is LOCAL for each ITexture (ie each ITexture will have his own Wrap mode) => no duplication is made.
UploadFormat may duplicate the texture in video memory. There is one texture per different UploadFormat.
