Detailed Description

Mixes together booleans with "or" while fitting the same interface as the other mixers in order to be simpler to use. This mixing method has a few benefits:

• An "average" for selections is relatively meaningless.
• Predictable selection propagation is very super important.
• It's generally easier to remove an element from a selection that is slightly too large than the opposite.

Member Function Documentation

finalize() [1/2]

void blender::bke::attribute_math::BooleanPropagationMixer::finalize ( )

inline

Does not do anything, since the mixing is trivial.

finalize() [2/2]

void blender::bke::attribute_math::BooleanPropagationMixer::finalize ( const IndexMask & )

inline

Definition at line 428 of file BKE_attribute_math.hh.

mix_in()

void blender::bke::attribute_math::BooleanPropagationMixer::mix_in ( const int64_t index, const bool value, const float weight = 1.0f )

inline

Mix a #value into the element with the given #index.

Definition at line 418 of file BKE_attribute_math.hh.

set()

void blender::bke::attribute_math::BooleanPropagationMixer::set ( const int64_t index, const bool value, const float weight = 1.0f )

inline

Set a #value into the element with the given #index.
