adding stl mesh makes other meshes disappear
andreadelprete opened this issue · comments
Hi, I am trying to visualize a UR5 robot together with a table in gepetto viewer. I first initialize the viewer and load the robot model using a pinocchio RobotWrapper, as usual. Then I load the table stl model using addMesh("world/table", "path-to-stl-file"). The result is that as soon as I load the table model, the table appears and the robot disappears from the viewer. If I do the operations in the opposite order (first loading the table, then the robot model) I get the opposite result, namely the table disappears as the robot appears. Any idea what might be going on?
I am working on a Ubuntu 20.04 virtual machine, using the ur5 model of example-robot-data and the following versions of gepetto-viewer packages:
ii robotpkg-py38-qt5-gepetto-viewer+doc 4.12.0r2 amd64 Humanoid Path Planner (Simple viewer based on OpenSceneGraph)
ii robotpkg-py38-qt5-gepetto-viewer-corba 5.6.0 amd64 Humanoid Path Planner (Corba server for gepetto-viewer)
Do you have a script to reproduce the error ?
This code can reproduce the error:
from example_robot_data.robots_loader import load
STL_FILE = '/home/adelprete/devel/src/locosim/ros_impedance_controller/worlds/models/tavolo/mesh/tavolo.stl'
robot = load('ur5')
robot.initViewer(loadModel=True)
robot.display(robot.q0)
import time
time.sleep(3.0)
robot.viz.viewer.gui.addMesh('world/table', STL_FILE)
The stl file can be found here.
I found the UR5
Do you have another one ?
I love this game: "find the UR5".
More seriously, I think there is a problem of scale. Your stl is expressed in millimeters.
Thanks @florent-lamiraux ! Sorry for the silly problem! :D
