CloudCompare forum

Daniel,

First off, thank you for all the work you do on Cloud Compare.

So, I am learning Python to create a plugin for Cloud Compare. I am trying to convert a lidar trajectory file into a path that can be used to create new viewports. At each idea, I keep running into "issues" with the python example files not executing.

For example, in the viewport example [CloudCompare-PythonRuntime/script_examples/viewport.py] the program errors with the message

import pycc
import cccorelib
CC = pycc.GetInstance()
pc = CC.getSelectedEntities()[0]
bbMin, bbMax = cccorelib.CCVector3(), cccorelib.CCVector3()
pc.getBoundingBox(bbMin, bbMax)
center = (bbMax - bbMin) / 2
center = cccorelib.CCVector3d(*center)
vp = pycc.ccViewportParameters()
vp.setCameraCenter(center, False)
vp.setFocalDistance(150)
glWindow = pc.getDisplay()

glWindow.setViewportParameters(vp)

glWindow.redraw()


"AttributeError: 'pycc.ccGenericGLDisplay' object has no attribute 'setViewPortParameters'

At:
<string>(19):<module>"

So, while I know this is an error with the example code, my lack of python experience is hindering my ability to "fix" it. Am I doing something wrong or is there no 'setViewportParameters' in the pycc import?


My idea is to have a small trajectory file with about 60 points. At each point along the trajectory, I would like the program create a TLC/GBL as that is the viewpoint I want. Looking through the python API, it seems you cannot create a ccGBLSensor point with the python api. Orr if you can, I am surely doing it wrong. So I started looking at using the viewport and creating that view and then inserting/creating a viewport object that could be combined into an animation.

Thank you for your hard work,
Bruce

Sorry for the late reply. This question should probably be asked directly on the Python plugin project's github page (https://github.com/tmontaigu/CloudCompare-PythonRuntime)
