How to add coordinate into SU api

zps222, please wrap your code in a code block.

Wrap your script in a unique module. 1. Do NOT paste the entire 'ocean.rb' into your script. Instead, use require to make sure it's loaded.


module Zps222
  module OceanTest
    require('Ocean/ocean.rb')

    # your code

    # do this BEFORE exporting model for surface ref
    # change the 'if' to 'unless' for bottom ref
    toggle_ocean() if is_on_floor_bottom()

    Sketchup.active_model.export("c;/2.kmz",false)

    UI.openURL("c;/2.kmz")

  end
end

Also you need to start using ( ) around your argument lists.
This can confuse Ruby:
face.pushpull -4000
Ruby may think you are trying to subtract integer 4000 from an object returned by the method on the left. Do this instead:
face.pushpull(-4000)
.

By the way.. I've heard that Google Earth models have to be "approved".

Is this so? Does a user see his uploaded model right away, or is it invisible until it's approved?
Or is it only invisible to other users, until it's approved?

FYI

Positive Latitudes are North of the equator; Negative are South.

Positive Longitudes are East of the Prime Meridian; Negative are West.

Another question is, if I build a model, and want to set the bottom of the model at a centain depth in the ocean, how to manage it?

First, open your Preferences dialog. Go to the Extensions panel.
Check (turn ON,) the "Google Earth Ocean Modeling" extension.

Then browse to the Sketchup directory: "Plugins/Ocean" and read the ruby script 'ocean.rb'

It appears that you will need to move everything in your model, either:

above the [0,0,0] origin, if you wish to place the model relative to the ocean floor, OR* below the [0,0,0] origin, if you wish to place the model relative to the ocean surface.
You will need to use the "Model on Ocean Floor" menu option that the Ocean extension adds to the Plugins menu.. BEFORE you upload the model to Google Earth.

Thans Dan.
I still can't figure it out.

For example, this is my example code:

# Create the new material
mats = Sketchup.active_model.materials
ct_mat = mats.add "Color_Texture"
ct_mat.color = "Red"

# Draw a Face and set its material
ents = Sketchup.active_model.entities
face = ents.add_face [1000, -1000, -5000], [1000, 1000, -5000], [-1000, 1000, -5000], [-1000, -1000, -5000]
face.material = ct_mat
face.pushpull -4000

Sketchup.active_model.shadow_info['Latitude']=29.060
Sketchup.active_model.shadow_info['Longitude']=-88.090

Sketchup.active_model.export("c;/2.kmz",false)

UI.openURL("c;/2.kmz")

def is_on_floor_bottom
  return Sketchup.active_model.get_attribute("GeoReference", "onOceanFloor") == "true";
end

def toggle_ocean
  on_floor = !is_on_floor_bottom()
  puts on_floor
  if on_floor
    Sketchup.active_model.set_attribute "GeoReference", "onOceanFloor", on_floor.to_s;
  else
    Sketchup.active_model.attribute_dictionary("GeoReference").delete_key "onOceanFloor";

item = menu.add_item($oceanStrings.GetString("Model on Ocean Floor")) { toggle_ocean }

Thanks Dan. I will try your code soon.

For your question, I can instaneously see the model on google earth, but it's only confined in my laptop, not publiclly to the internet. If wanted to publicate it, as far as I know, there are 3 ways:
the most comon way is to upload the model into "google 3D warehouse" to let people download them into to "local" google earth. The sencond way is to embed the google earth into the website and the locate the KMZ into the server, then on the website, people can see it. The third way is to get the permission to publize it into official google earth.

What about ??
Sketchup.active_model.shadow_info['Latitude'] Sketchup.active_model.shadow_info['Longitude']

I believe these are set by the Model Info > Location feature.

Thank you Dan and Jim.
Still, I can't figure it out.
Simply as an example,

# Access the Entities object
model = Sketchup.active_model
ent = model.entities

# Create the 2-D shape of the axis
axis = ent.add_face [0, -500, 0], [250, -433, 0],
                      [433, -250, 0], [500, 0, 0],
                      [433,250, 0], [250, 433, 0],
                      [0, 500, 0], [-250, 433, 0],
                      [-433, 250, 0], [-500, 0, 0],
                      [-433, -250, 0], [-250, -433, 0], [0, -500, 0]


# Create the 3-D shape of the axis
total_depth = -2060
axis.pushpull total_depth

#creat one simple 3-d vector, North at the bottom
vector1 =ent.add_face [-500,0,0],[500,0,0],
                   [500,1500,0],[750,1500,0],
                   [0,2000,0],[-750,1500,0],
                   [-500,1500,0] 

vector_depth=-50
vector1.pushpull vector_depth

Here is my simple code, if I want to they located at lat= 10, lon=10, how to manege it?

Really appratiate.

zps222,

The description of the Google Earth Ocean Modeling extension says,
"Adds the ability to model on the ocean floor after taking a snapshot from Google Earth."

So try taking a shapshot first.

.
Here's some commands you can use at the console, for info:

dicts=Sketchup.active_model.attribute_dictionaries dicts['GeoReference'].each { |key,value| p key.to_s + '=' + value.to_s }

how can i put a simple model in the required location? i did the following coding
model = Sketchup.active_model
pt = Geom::point3d.new(0,0,0)
tr = Geom::Transformation.new(pt)
model.transform!(tr)

and it gives me this error:
#<NoMethodError: undefined method `point3d' for Geom:Module>

thankss

Because methods begin with lower case identifiers.
Class (and Module,) indentifiers are titlecase.

The model origin is already at [0,0,0], and there is a constant ORIGIN for it.
So your code above does nothing.
