Detailed Description

+A CTextureFar is a set of NL_NUM_FAR_PATCHES_BY_TEXTURE texture used to map a whole patch when it is in far Mode. +

+(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 +

+Add a patch in the CTexture Patch. +

+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.

+
+ + + + + +
+   + + +

+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. Can be 64, 32, 16, 8, 4 or 2
