shape vertex to marker conversion script

[dussla]

Hi friend
I have a sone problem
I am seeking python
"shape vertex  to marker conversion script"

Pls  Can you help  this problem

Hello dussla,

Do you need just to get the newly created markers, which correspond to the 3D locations of all the vertices of the shapes in the project?

[dussla]

Yes  right  ~~~~~

Really   thank you for reply....

Hi alexey
Pls  i am wating your good answer

Hello dussla,

Please check, if the attached script works as expected.

It should create new markers, corresponding to 3D vertices of all the shapes in the active chunk.
Markers will be grouped to the marker groups named according to the original shape type and label.

Code: [Select]

import Metashape

def flatten_list(input_list):
if not input_list:
return []
output_list = []
for i in input_list:
if not isinstance(i, list):
output_list.append(i)
else:
output_list += flatten_list(i)
return output_list

chunk = Metashape.app.document.chunk
if not chunk:
print("Empty project, script aborted.")
return 0
if not chunk.shapes:
print("No shapes in the active chunk, script aborted")
return 0

num_ignored = 0
num_processed = 0
num_markers = 0
for shape in chunk.shapes:
if shape.is_attached:
shapes.append(shape)
continue
elif shape.geometry.is_3d:
shapes.append(shape)
continue
num_ignored += 1

for shape in shapes:
if shape.is_attached:
markers = shape.geometry.coordinates
if not len(markers):
continue
num_ignored += 1
new_group = chunk.addMarkerGroup()
new_group.label = str(shape.geometry.type).rsplit(".",1)[1][:-4] + "_" + str(shape.key) + " (" + shape.label +")"
markers = set(flatten_list(list(markers)))
markers = [marker for marker in list(chunk.markers) if marker.key in list(markers)]

new_marker = chunk.addMarker()
new_marker.label = new_group.label + "_" + str(n)

markers.pop(-1)

return 1
