Member Function Documentation

bool NL3D::CLodCharacterShape::addAnim (  const CAnimBuild &    animBuild ) 
 

Add an animation.

many nlAssert to verify array size etc... return false, if same AnimName exist. NB: the entire animation is compressed to CVector3s internally.

void NL3D::CLodCharacterShape::addBoneColor (  uint    boneId,
CRGBA    color,
std::vector< NLMISC::CRGBAF > &    tmpColors
)  const
 

Add a bone color influence to tmpColors.

Definition at line 639 of file lod_character_shape.cpp.

References _Bones.

void NL3D::CLodCharacterShape::buildMesh (  const std::string &    name,
const CLodCharacterShapeBuild &    lodBuild
) 
 

build the Mesh base information NB: SkinWeights array tells for each vertex what bone color to use.

void NL3D::CLodCharacterShape::endBoneColor (  const std::vector< NLMISC::CRGBAF > &    tmpColors,
std::vector< NLMISC::CRGBA > &    dstColors
)  const
 

Compile boneColor result into a CRGBA vector (resize-ed by the method), averaging with weight stored in A.

NB: if a final vertex is not influenced by any BoneColor, then it will receive (128,128,128,0). Hence it will be somewhat transparent (AlphaTest is used to render lod character shapes). This may be interressant to hide some parts if they are not used.
