how to get the size of a mesh?

[hit2501]

Hi.

I want to know if scaling.x or .y or .z is the only way to get the dimensions of a mesh (imported from blender).

Thanks

Personnaly, I use this: http://www.babylonjs-playground.com/#1NZLA9

 

To have the size, you just have to do: size.scaleInPlace(2)

Thank you very much Temechon I followed your Babylon example It's more closer to the real model with BoundingInfo but I don't know how to use scaleInPlace, I put: mymesh.scaleInPlace(2);

But doesn't work, what am I doing wrong?

Sorry if its too basic, I'm a Babylon noob.

I saw that the units used to show position are different, what kind of unit is used for position and what units for boundingInfo

Once more, thank you

Sorry, I guess I was too fast as answering (very common these days, I have to calm down:) )

 

This gives you the 'extends' size of your mesh: the number of units between the center of the mesh and the side of the mesh (along x, y and z axis):

var size = sphere.getBoundingInfo().boundingBox.extendSize;

For the sphere in my example, 'size' will then correspond to its radius.

For a box of scaling (1,1,1), this piece of code will returns (0.5,0.5,0.5).

 

If you want to have the diameter, you just have to scale this radius by 2, like this:

var diameter = size.scale(2);

Is it clearer now?

 

To anser to your second question, all units in Babylon are the same: position, boundingInfo, scaling...

Thanks Temechon!  In case anyone is wondering who asked for clarification (via PM), it was I.    Yep, I understand it perfectly, now.  Very good.

Crystal clear. Thank you very much Temechon
