solved Create dynamic surface elevation

[Dieterich]

What best way to create dynamic surface elevation?

In my case, I want up/down elevations in one surface...as shown in the figure the elevation points in blue.

This my starter case:

Can you use a texture for that?

Else you would need to manually edit the mesh data:

Hi @Deltakosh

Hey, see this: http://playground.babylonjs.com/#1XBLWB#227 

This example is more approximate.

One question. How up/down the subdivisions?

 

OBS: I don't use image for create surface..

Great! ?

I need learn the option to update vertices..

1. But, why the 'updatable' do not necessary in 'CreateTiledGround'? or I don't know correctly your function??
2. Why on define 'wireframe' false, the faces they are not connected?

you could also consider using a ribbon : http://doc.babylonjs.com/how_to/ribbon_tutorial

1. Updatable is a hint for the graphics card. You should use it when you know that the mesh will be updated multiple times: this way the data will be in a memory that both CPU and GPU can reach. It is less efficient than setting updatable = false because in this case the data will be in fast GPU memory. When updatable = false, calling setVerticesData will recreate the content (which is ok if you do it just a few times)

2. This is because your faces do not share vertices: You can replace the TiledGround by a regular ground: http://playground.babylonjs.com/#1XBLWB#231

Your tips are productive. I'm elaborating some examples and in the sequence I will ask some tips.

Thanks a lot! see you later.

Hi!

How make the smooth appearance? it's possible?

[jerome]

if you set a random elevation each vertex, you'll get something very sharp.

You could use some math function to get more linearity or a perlin noise function

[Dieterich]

This is new for me, 'perlin noise function'. I go look this function..

The problem is that my surface must be dynamic, I have to think better how I'm going to do ..

Thanks @jerome
