Hello,
new to Project Chrono. I have been messing around to familiarize myself
with this great project.
I'm unable to change color of objects imported as mesh (obj), here is a
sample code. Green line is where I try to set the color.
What am I 'missing? No matter what color I set, it always shows white.
*import pychrono.core as chimport pychrono.irrlicht as chirrimport
pychrono.cascade as cascadefrom OCC.Core import TopoDSimport math# Create
systemsys = ch.ChSystemSMC()# Create bodies# NOTE: pendulum
pinbody_pendulum_pin =
ch.ChBody()sys.Add(body_pendulum_pin)body_pendulum_pin.SetMass(10)body_pendulum_pin.SetInertiaXX(ch.ChVectorD(20,
20, 20))body_pendulum_pin.SetPos(ch.ChVectorD(0, 0,
0))body_pendulum_pin.SetRot(ch.ChMatrix33D(ch.ChVectorD(1, 0, 0),
ch.ChVectorD(0, 0, -1), ch.ChVectorD(0, 1,
0)))body_pendulum_pin.SetBodyFixed(True)mesh_pin =
ch.ChTriangleMeshConnected()mesh_pin.LoadWavefrontMesh(ch.GetChronoDataFile('models/my_models/pendulum_pin.obj'))vis_shape_pin
=
ch.ChTriangleMeshShape()vis_shape_pin.SetMesh(mesh_pin)vis_shape_pin.SetColor(ch.ChColor(0.5,
0.5, 0.5))body_pendulum_pin.AddVisualShape(vis_shape_pin)#

ch.ChVectorD(0, 0, 0))vis.AddTypicalLights()# ------------------# Run the
