scaling up and down properly

[cellis]

Hello

i am trying to scale a mesh like this

scale = .2;
mesh.scale(scale);

this works, but when i do this

scale += .05
mesh.scale(scale);


it is smaller. Why?

[David Parks]

I believe the scale is always relative to the current size. So you reduced
it by 20% in the first round, then you reduced it by 25% in the second
round.

i thought calling .scale() was setting it to that value, not
transforming it by a percentage??

The mesh.geometry object holds a scale variable. Allowing fast non
destructible scaling options.
If you want to apply a scale at vertex level, just parse the vertices
array and multiply the components.

if you want to set absolute scale, you can use the scaleX/scaleY adn scaleZ proprties

the scale() method applies a further scale to an already scaled object, in much the same way that scale() works on a native matrix object
