4. ## Rotate an object perpendicular to the surface of a sphere

Hi folks, here I am bothering you on this forum hahaha. I've tried, unsuccessfully, to rotate a tree so it can be perpendicular to the surface of an sphere at some point. You can see what I did at http://uvshop.co/mimundo/. (I have use, without his permission, @Temechon trees, you can visit his tutorial here) The trees positions are genereted by using a random theta and phi angles: Here is a pic And heres is another Thanks in advances and sorry for my bad english

6. ## Move RTS ArcRotateCamera

Hi Chris, I can't understand what you need. Isn't just translate the camara position and keep looking to the same point? Also, could you please give us a hand by using http://www.babylonjs.com/playground/ for a simple example? Regards, Carlos.

13. ## Retrieve heightmap altitude

Hi guys, i'm trying to retrieve the altitude of a heightmap but nothing happends. Here i have an example using a simple groundMesh: http://www.babylonjs.com/playground/#24LCDU#1 , You can see that it works well, at any given coordinate (x,z), i could retrive the 'y' value. But not with CreateGroundFromHeightMap, not anymore . Check this example: http://uvshop.co/babylonjs/problema/ Also, i try to use 'ground.intersects(rayo, false).pickedPoint' but nothing happends. What can i do? Thanks in advance, Carlos-R
