(ie not in tile mode). A CTextureFar handle several patch texture.\ Before adding patch to the texture, you must call setSizeOfFarPatch, to intialize the texture. TODO: keeping the far texture level1 alive when the tile pass in level0 (tile mode), don't erase it. TODO: add an hysteresis to avoid swap of far texture on boundaries of levels TODO: set the upload format in rgba565 Author: Cyril Corvazier , Nevrax France Date: 2000 Definition at line 67 of file texture_far.h.

Must not be full! Return true if the texture is full after adding this patch else false. Parameters: pPatch  is the pointer to the patch to add in the landscape far1UVScale  will receive the scale to use to compute the UV coordinates far1UBias  will receive the U Bias to use to compute the UV coordinates far1VBias  will receive the V Bias to use to compute the UV coordinates bRot  will receive true if the texture is rotated of 90° to the left or false. You should take care of this value to compute UV coordinates.

Reimplemented from NL3D::ITexture. Definition at line 168 of file texture_far.h. void NL3D::CTextureFar::setSizeOfFarPatch (  sint    width, sint    height )    Set the size of the patch stored in this texture far. Note that width must be larger than height. For patch with a bigger height than width, invert width and height value. So, in this texture far, you can store patches with a size of width*height but also patches with a size of height*width. Parameters: width  is the width of the texture far stored in this texture. Can be 64, 32, 16, 8, 4 or 2 height  is the height of the texture far stored in this texture.
