weightvg_do_map()

void weightvg_do_map	(	int	num,
		float *	new_w,
		short	falloff_type,
		bool	do_invert,
		CurveMapping *	cmap,
		RNG *	rng )

Maps new_w weights in place, using either one of the predefined functions, or a custom curve. Return values are in new_w. If indices is not NULL, it must be a table of same length as org_w and new_w, mapping to the real vertex index (in case the weight tables do not cover the whole vertices...). cmap might be NULL, in which case curve mapping mode will return unmodified data.

weightvg_do_mask()

void weightvg_do_mask	(	const ModifierEvalContext *	ctx,
		int	num,
		const int *	indices,
		float *	org_w,
		const float *	new_w,
		Object *	ob,

		int	tex_mapping,
		Object *	tex_map_object,
		const char *	text_map_bone,
		const char *	tex_uvlayer_name,
		bool	invert_vgroup_mask )

Applies new_w weights to org_w ones, using either a texture, vgroup or constant value as factor. Return values are in org_w. If indices is not NULL, it must be a table of same length as org_w and new_w, mapping to the real vertex index (in case the weight tables do not cover the whole vertices...). XXX The standard "factor" value is assumed in [0.0, 1.0] range. Else, weird results might appear.

weightvg_ui_common()

void weightvg_ui_common	(	const bContext *	C,
		PointerRNA *	ob_ptr,

		uiLayout *	layout )

weightvg_update_vg()

void weightvg_update_vg	(	MDeformVert *	dvert,
		int	defgrp_idx,
		MDeformWeight **	dws,
		int	num,
		const int *	indices,
		const float *	weights,
		bool	do_add,
		float	add_thresh,
		bool	do_rem,
		float	rem_thresh,
		bool	do_normalize )

Applies weights to given vgroup (defgroup), and optionally add/remove vertices from the group. If dws is not NULL, it must be an array of MDeformWeight pointers of same length as weights (and defgrp_idx can then have any value). If indices is not NULL, it must be an array of same length as weights, mapping to the real vertex index (in case the weight array does not cover the whole vertices...).
