Height of a point on the ground

[Dad72]

hi,

 

How do I get the height (Y-Axis) of a point on the ground by pickinfo. I would like to add to the grass when we click on a points of ground.

I am missing just the point Y of the place clicked for that my grass is not below the ground when she is added.

 

Thank you for your help.

Nobody has an idea? please.

var point = scene.pick(e.clientX, e.clientY);

if(point.pickedPoint){

var pointY = point.pickedPoint.y;

}

Thank you, but I was talking about to retrieve the point Y of the terrain when I click on a places any of the ground.
here on a pickedpoint, it retrieves the position x and z of an object. The x and y position of a pickedpoint are in a world 2d and me I wish the Y position of the 3d world.

Hi,

 

You should have a look to the Worldmonger demo. on babylon website. I think there is what you want.

 

Another solution would be at start up to store in an array each pixels of your heightmap . After with your event x z and few calculations, just look in the array at the right index  to get your y elevation (the gray level), etc..and adapt it to your world.

Thank you Samuel. I know this Worldmonger demo. I use it in my project where I've added functionality for my game editor. But I do voi not where recover the height of a point following the click. I'll look again.

 

May be that Deltakosh would have a idea?

In fact, I've just test  

 

var pickResult = this.scene.pick(evt.clientX, evt.clientY);

 

 this.iniScene.moveBox(pickResult.pickedPoint); 

 

pickResult.pickedPoint is vec3 (x,y,z) , and I can move a box at the right  heigh on my ground terrain.

Thank you very much Samuel, I am going to test this.

[Dad72]

Yes, this has run. I did not know that pickedpoint retrieve a Vector3. in the documentation, it says that it is a Vector2.

 

But thank you for your help.

[Dad72]

No probleme Temechon. Thanks for the fix.
