Merge Meshes

[Maxence 1]

Hi,

 

Thanks Deltakosh for your wiki page about merging meshes (https://github.com/BabylonJS/Babylon.js/wiki/How-to-merge-meshes).

It helped me to create a function to merge a mesh to another one. I added the function to your Mesh class and I could send you a pull-request if you want.

 

Nevertheless I'm not totaly happy about it since I didn't manage to avoid to create a new mesh to contain the result of the merging. Indeed, I think it could be helpful to directly modify the first mesh to be the merged mesh, thus the process could be simpler to chain meshes merging (and I need this ) and more efficient.

 

Here are two jsfiddles. The first one gives the good result but a new mesh has to be created, the second one avoids the creation of a new mesh but the result is translated and I don't understand why.

(only two lines are different: l48 and l65)

Because you are baking your worldMatrix into vertices, do not forget to set position, rotation and scaling to default values on your mesh

Thanks for your answer, 

 

I found a solution this morning,

 

could you please tell me if it seems to be the right way to solve the problem.

 

I made a jsFiddle to explain my choice.

(change l61 and l70-75).

This is correct
