setColor In Python Script

[Brad Humphreys]

I am looking for some example text in how the color of a body can me changed in a python script. The body was created using:

block.addDisplayGeometry("PART.obj")

I have tried using the DisplayGeometry class under openSim to no avail.

Thanks!

Brad

Hi Brad,

The distribution include a script to set color in the GUI. If you want to set the color from a generic Python script you'd use the following code snippet:

Code: Select all

pelvis = model.getBodySet().get('pelvis')
displayer = pelvis.getDisplayer()
geometrySet = displayer.getGeometrySet() 
gi = geometrySet.get(0)
gi.setColor([1, 0, .5])

Hope this helps,

Ayman,

Thanks! Works great. IMHO, this would be a good example for documentation of the python scripting. While "color" is a bit secondary, your code snippet maps/keys well to the doxygen documentation hierarchy.
