Bounding Box Attributes

[[De...]]

Hi, I was wondering if anyone knew how to utilize the bounding box attributes?
As an example, lets take a patch compound created on a subset of surface patches.

Here's a random patch compound as an example:





The bounding box min attribute = gom.Vec3d(x,y,z)
maximum =  gom.Vec3d(x,y,z)
what do these #s represent? How does 1 point represent a box?




I'm trying to determine the bounding box / center point of a patch compound (ideally without creating fitting points/elements).
Any help would be greatly appreciated!

Hi Devon,

Just a wild guess: Maybe the bounding box is defined by two opposite corners defined by the minimum/maximum coordinates?

Best regards,

Matthias

Thank you Matthias!  😃

	# Extract the maximum point coordinates
	x_max = obj.bounding_box.max.x
	y_max = obj.bounding_box.max.y
	z_max = obj.bounding_box.max.z
	
	# Generate the 8 corners of the bounding box
	corners = [
		(x_min, y_min, z_min),

	length = x_max - x_min

	height = z_max - z_min
	
	return corners, center, length, width, height


obj = gom.app.project.inspection['random_surface']

corners, center, length, width, height = extract_bounding_box(obj)

print("Corners:", corners)
print("Center:", center)
print("Dimensions (Length, Width, Height):", length, width, height)
