Macro Definition Documentation

EXPAND_ACTIVE_COMPONENT_NONE

#define EXPAND_ACTIVE_COMPONENT_NONE   -1

Used for defining an uninitialized active component index for an unused symmetry pass.

Definition at line 92 of file sculpt_expand.cc.

Referenced by blender::ed::sculpt_paint::expand::find_active_connected_components_from_vert().

SCULPT_EXPAND_LOOP_THRESHOLD

#define SCULPT_EXPAND_LOOP_THRESHOLD   0.00001f

This threshold offsets the required falloff value to start a new loop. This is needed because in some situations, vertices which have the same falloff value as max_falloff will start a new loop, which is undesired.

Definition at line 104 of file sculpt_expand.cc.

Referenced by blender::ed::sculpt_paint::expand::face_state_get(), blender::ed::sculpt_paint::expand::gradient_value_get(), and blender::ed::sculpt_paint::expand::vert_falloff_is_enabled().

SCULPT_EXPAND_NORMALS_FALLOFF_EDGE_SENSITIVITY

#define SCULPT_EXPAND_NORMALS_FALLOFF_EDGE_SENSITIVITY   300

Defines how much changes in curvature in the mesh affect the falloff shape when using normal falloff. This default was found experimentally and it works well in most cases, but can be exposed for tweaking if needed.

Definition at line 111 of file sculpt_expand.cc.

Referenced by blender::ed::sculpt_paint::expand::calc_falloff_from_vert_and_symmetry().

SCULPT_EXPAND_TEXTURE_DISTORTION_STEP

#define SCULPT_EXPAND_TEXTURE_DISTORTION_STEP   0.01f

Defines how much each time the texture distortion is increased/decreased when using the modal key-map.

Definition at line 97 of file sculpt_expand.cc.

Referenced by blender::ed::sculpt_paint::expand::sculpt_expand_modal().

SCULPT_EXPAND_VERTEX_NONE

#define SCULPT_EXPAND_VERTEX_NONE   -1

Used for defining an invalid vertex state (for example, when the cursor is not over the mesh).

Definition at line 89 of file sculpt_expand.cc.
