Make Only certain boxs render


Recommended Posts


How can I stop the boxes that are not needed to be displayed because they are covered by other blocks not compute?

If i increase the grid size to like 32 or even 64 then it lagggggggsssss....  especially if I increase the height. There is a lot of useless script in there I whipped this up in like 20 mins just to get the idea down, now I want to extend and refine it.

we need to re-run (press back on RUN after first load) your PG because the perlin noise script is not loaded.

Btw, you don't need to write "new" before the calls to "CreateXXX()" what are static methods.

If you want to set a mesh as invisible "mesh.isVisible = false;" should do the trick.

In your PG, actually you create many (2000+) similar meshes (boxes). Maybe you should consider using "instances" instead : http://doc.babylonjs.com/tutorials/How_to_use_Instances

or a solid particle system : http://doc.babylonjs.com/overviews/Solid_Particle_System

Both will render only one mesh ;)
