The Mesh object has the scale property. Just do mesh.scale.x = 2 or mesh.scale.set( 2, 1, 1 ).

i have the same problem as the guy over there: http://stackoverflow.com/questions/19150120/scaling-an-object-in-three-js

the moment i change scale i get flooded with:
"Matrix3.getInverse(): can't invert matrix, determinant is 0"
in three-r73.js:4482:5

I get the same error. Using THREE.CylinderGeometry

@gunderson Try stackoverflow if you need help.

If you have a group of objects, try to add them to a group as rendering parent and scale the parent...

const renderingParent = new THREE.Group();
// ...
renderingParent.scale.set(2,1,1);
renderingParent.add(groupOfObjects);

What if I am constantly changing? (I don't want to calculate scales 10 times)
Isn't there a method that actually changes the geometry width and height?
