Problem with refreshBoundingInfo()

[Bob Razowsky]

Hi everybody,

 

I have a problem using refreshBoundingInfo().

In my script, I scale an object, and I need to place meshes at it's extremity.

Even after using refreshBoundingInfo(), bounding infos don't change.

 

Am I missing something here?

 

Thanks for your answers!

Hi Bob,

try reproducing the problem in the playground, this way we can all try and help out.

Box2 should be in the bottom left corner.

So, technically, you are right :-) According to what one can understand from minimum and maximum, it should work. there is always a "But" :-)

A few pointers:

1) After scaling and before the scene renders at least one time, you will have to compute the 1st box's world matrix, to get the scaling factors integrated in its transformation.

2) minimum and maximum are confusing. If you wish to use the bounding box that is calculated using the world matrix, you need to use minimumWorld of the bounding box

 

This is an example - http://www.babylonjs-playground.com/#WO4DY#1

Perfect, thank you very much!

Minimum and maximum are in obejct space so they won't never change. As Ranaan mentioned, the minimumWorld and maximumWorld are the good to use
