RelaxCollisions

SynthChainStep to relax collisions between objects of a set, using Blenders

Functions

_convert_to_mesh_recursively(→ None)	Recursively iterate through a tree of blender objects, and starting from
_apply_transforms_recursively(→ None)	Recursively apply a transform to a Blender object and all its children.

synthpic2.recipe.synth_chain.feature_generation_steps.relax_collisions._convert_to_mesh_recursively(blender_object: bpy.types.Object) → None

Recursively iterate through a tree of blender objects, and starting from the leaves and working up to the root, convert the objects to meshes. Unfortunately, this breaks parent/child relations, so we have an option to restore them _and_ it also breaks the references to blender objects, so we set the context object to the ultimate parent.

Args:

blender_object (bpy.types.Object): Blender object (potentially with children) to

convert to mesh.

Args:
