MergeMeshes Optimisation

[Jaskar]

Hello dear Babylon lovers! 

 

I'll try to be clear : For the Babylon monthly challenge, I create a random maze, with many meshes. Then, I merge all the meshes for performance reason.

It looks something like this http://www.babylonjs-playground.com/#QDDWX (better than this  )

 

My question is : It merges the meshes, it's ok, but what about the inside faces ? Is it possible to remove it (the faces you can see inside the boxes) ?

I'd use CSG.

[jerome]

didn't you want the inside faces to visible ... inside ?

@adam : Perfect! Thanks 

 

@jerome : Nop, it's not my goal. Thanks for the hint anyway 

 

My algorithm produce something that look like this : https://en.wikipedia.org/wiki/Maze_generation_algorithm#Depth-first_search

So, I create a lot of cubes, that I merge after. Then, I don't care about inside faces.

I just applied it to my Maze.

On a 10*10 maze (walls are simple boxes), it's ok. But, on a 60*60 (with approximately 2000 boxes), CSG is so sloooow! It's impossible.

So, I will only use MergeMeshes.
