Typedefs
Mix a dynamic amount of values with weights for many elements.
This section provides an abstraction for "mixers". The abstraction encapsulates details about how different types should be mixed. Usually DefaultMixer<T> should be used to get a mixer for a specific type.

Typedef Documentation

DefaultMixer

template<typename T >

using blender::bke::attribute_math::DefaultMixer = typename DefaultMixerStruct<T>::type

Definition at line 649 of file BKE_attribute_math.hh.

DefaultPropagationMixer

template<typename T >

using blender::bke::attribute_math::DefaultPropagationMixer = typename DefaultPropagationMixerStruct<T>::type

This mixer is meant for propagating attributes when creating new geometry. A key difference with the default mixer is that booleans are mixed with "or" instead of "at least half" (the default mixing for booleans).

Definition at line 645 of file BKE_attribute_math.hh.
