Method Details [hide private]

get_tangent_space(self)

source code 
Return iterator over normal, tangent, bitangent vectors. If the block has no tangent space, then returns None.

update_tangent_space(self, as_extra=None, vertexprecision=3, normalprecision=3)

source code 
Recalculate tangent space data.
Parameters:
  • as_extra - Whether to store the tangent space data as extra data (as in Oblivion) or not (as in Fallout 3). If not set, switches to Oblivion if an extra data block is found, otherwise does default. Set it to override this detection (for example when using this function to create tangent space data) and force behaviour.

update_skin_partition(self, maxbonesperpartition=4, maxbonespervertex=4, verbose=0, stripify=True, stitchstrips=False, padbones=False, triangles=None, trianglepartmap=None, maximize_bone_sharing=False)

source code 
Recalculate skin partition data.
Parameters:
  • maxbonesperpartition - Maximum number of bones in each partition. The num_bones field will not exceed this number.
  • maxbonespervertex - Maximum number of bones per vertex. The num_weights_per_vertex field will be exactly equal to this number.
  • verbose - Ignored, and deprecated. Set pyffi's log level instead.
  • stripify - If true, stripify the partitions, otherwise use triangles.
  • stitchstrips - If stripify is true, then set this to true to stitch the strips.
  • padbones - Enforces the numbones field to be equal to maxbonesperpartition. Also ensures that the bone indices are unique and sorted, per vertex. Raises an exception if maxbonespervertex is not equal to maxbonesperpartition (in that case bone indices cannot be unique and sorted). This options is required for Freedom Force vs. the 3rd Reich skin partitions.
  • triangles - The triangles of the partition (if not specified, then this defaults to C{self.data.get_triangles()}.
  • trianglepartmap - Maps each triangle to a partition index. Faces with different indices will never appear in the same partition. If the skin instance is a BSDismemberSkinInstance, then these indices are used as body part types, and the partitions in the BSDismemberSkinInstance are updated accordingly. Note that the faces are counted relative to L{triangles}.
  • maximize_bone_sharing - Maximize bone sharing between partitions. This option is useful for Fallout 3.

Deprecated: Do not use the verbose argument.

get_interchangeable_tri_shape(self, triangles=None)

source code 
Returns a NiTriShape block that is geometrically interchangeable. If you do not want to set the triangles from the original shape, use the triangles argument.

get_interchangeable_tri_strips(self, strips=None)

source code 
Returns a NiTriStrips block that is geometrically interchangeable. If you do not want to set the strips from the original shape, use the strips argument.
