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.

  • 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.
  • MinFilter may duplicate the texture in video memory in the same way, wether the texture has mipmap or not.
