Methods desciption :
init
def __init__(self)
Instantiotion method
Attributes
- _component : list of subnodes : either assembly or component
add_component
def add_component(self, component, update=False)
Add a sub node
- → component: the sub node
- → update: if the bounding box must be updated or not
if many sub-components are added, it is better to wait the last one before updating the bounding box.
remove_component
def remove_component(self, component, update=True)
Remove a sub node
- → component: the subnode to be removed
- → update: update the bounding box
get_component
def get_component(self, num=-1)
Get sub component from index
- → num: the index in [-1,n-1] where n is the number of component
- ← the indexed component or the list of sub node if n=-1
if num==-1 : return list_of_subnodes
elif num in range(0,n) : return sub_node[num]
else : return None
get_all_components
def get_all_components(self, SET=None)
Get all the sub components of the current assembly Recursive traversal of the hierarchy of assembly and add all components in a flat set
- → SET: Add the components to the current SET for recursivity
- ← return the set of expected components
lock_all
def lock_all(self)
Recursive lock of every sub node of the bom
save_frame
def save_frame(self, frame='', previous=None, sequence=None)
save current position as a frame if previous is not None then the frame is save if position is new respect to previous in the current sequence
goto_frame
def goto_frame(self, frame='')
Set every subnode of the current assembly to the frame position
- → frame: expected frame
center
def center(self)
Recursive construction of the assembly center
- ←
update_bounding_box
def update_bounding_box(self)
Recursive computation of the assembly bounding box
- ← the computer bounding box
urdf_string
def urdf_string(self, where='', urdf='')
Complete urdf string for the assembly
- → where: location of wavefront shapes
- → urdf: the urdf string to complete
- ← the competed urdf string
