lowering a 3D model 3 feet

[Steve Bull]

I am trying to present a field of a taro crop that is 1000' x 500' x 3' high as a very simple 3D model. See stevebull.blogspot.com/2012/10/taro-field-1000-x-500-x-3.html for the SketchUp Pro 2D rendering. I am having reasonable success exporting the model as .obj and then encrypting it and having it appear on my iPad2. But I have two issues to solve:

1. On the iPad2 browser, the model appears mid-screen when I want to deliver the model starting at ground level height.
// current code
$poi = $jPoiBuilder->create3DLocationBasedPOI(
    "Taro",    //name
    "21.299393,-157.817520,0", //position.....
 
I know, I know, I'm using the old method....sigh....however, I presume I should change the // position to
"21.299393,-157.817520,-1.0" .... does this take the model down 1 foot or 1 meter?

Any other thoughts on this matter with regards to the latest browser support for 3D models is appreciated.

2. The 2d output from SketchUp at stevebull.blogspot.com/2012/10/taro-field-1000-x-500-x-3.html shows my desired tile method to artfully suggest a taro field on a rectangular solid. However, in the browser view only the first panel is tiled and rest not. Tiling suggestions are gratefully solicited.
and here is my materials file code:

Hi Steve,

For question 1, please have a look at http://helpdesk.metaio.com/questions/107/how-can-i-lower-a-3d-model-by-3-feet?page=1#108

thanks,

I will try this. Thanks, Steve

Hi Steve,

if the texture doens't show up on the other parts of the model I would assume that the UV-mapping for those parts is not correct or not existing at all. The mtl does look ok, so most likely the problem is related to the geometry-definition in the obj.file

Can you maybe post the obj-file so that we can have another look at it?

Best regards
