Rhino

Overview

The NVIDIA Omniverse™ Rhino Connector offers a toolkit for Rhino Users to send and live sync their model(s) to an NVIDIA Omniverse™ Nucleus Server. This not only gives Rhino access to a first class renderer through NVIDIA Omniverse™ View or Kit but also the ability to open, edit and sync with any of the OMNIVERSE® Connect applications. Now, depending on the use case, Rhino users can choose the workflows and pipelines that work best for their needs while maintaining up to date revisions for all downstream consumers of their work.

Install Instructions

Deprecated in 2020.3 Please see Launcher Documentation for Installing Connectors.

Installing the OMNIVERSE® Plugin is done through the Rhino Plugin Manager and requires the install of the OMNIVERSE® AEC Experience or the NVIDIA Omniverse™ Rhino Connector (Standalone).

User Interface

The NVIDIA Omniverse™ Rhino Connector Plugin brings Rhino Projects into the OMNIVERSE® Platform through the use of connect tools similar to other NVIDIA Omniverse™ Connect applications.

UI Overview

Send to NVIDIA Omniverse™ View

Sends your file directly to NVIDIA Omniverse™ View. Simply click “Send to View” and NVIDIA Omniverse™ View will launch with your model loaded and ready to go.

Send to View

Note

You must be sure that NVIDIA Omniverse™ View is installed or that you can access it from a server for this feature to work. See the Connecting to VIEW® (Local) for more details.

Materials

When sending your materials to NVIDIA Omniverse™ View, we replace the low quality textures and shaders associated with Rhino and replace them with High Quality Custom Materials inside of NVIDIA Omniverse™ View. This is done by material mapping and can be controlled via CSV.

CSV and Materials

The CSV Mapping File for Rhino can be located in the following directory.

<Documents>/Omniverse/Rhino/omniverseRhinoMDLtable.csv

CSV File Structure

A CSV file is a Comma Separated Values table of data whose field’s end is defined by a comma ‘,’.

Using Spreadsheet Tools

These tables are a very common format and can be opened/edited inside of MS Excel (or other spreadsheet tools) and will have 5 columns in them when viewed.

Format

Column

Expected Value

Column A
Name of the material from the application.
Note: Any commas (,) are replaced with an asterisk (*)

Column B
Indicates if there is a parameter override | NONE: default, no special characteristics | COLOR: the 5th column (Column E) will have the parameter name in the MDL
GENERIC: keyword and last resort match in mapping (looks for the value in Column A
in the string of the material name we get from the application e.g. if Column A is
glass and the material from Rhino was Special Glass then it would match)
EXCLUDE: materials found in the application but NOT mapped, user could convert these
to real mappings by setting to NONE and changing the values in Column C/D/E (potentially)

Column C
MDL name (no .MDL)

Column D
Path into the location in the Omniverse database (points to a Mount)

Column E
If necessary, the parameter override in MDL

Grasshopper

Grasshopper is an extension that began shipping with Rhino in version 6 and is supported in NVIDIA® OMNIVERSE® through the NVIDIA Omniverse™ Rhino Connector Plugin. Because of this, Grasshopper makes possible node-based procedural building on the OMNIVERSE®.

Grasshopper Components

Grasshopper users will be happy to know that OMNIVERSE® requires very little to change in their current workflow as all interactions are handled through 4 OMNIVERSE® Components.

OmniGrasshopper Component

This is the main module for the OMNIVERSE®. Any OmniLayer Group wired to this node is published. This is the final node of the graph and only one publish node per canvas is allowed.

OmniGrasshopper Module Properties

Input

OmniLayer

OL

Object group with layer name and material

Input

Project Folder PATH

P

Parent project file path

Input

File Name

FN

File Name override used for publish and STV

Button

Live Sync

When ON enables “Live Sync”. When OFF (default) Live Sync is disabled

Button

Send to View

Click to start Send to View process

Button

Publish

Click to start the publish process

OmniLayer Component

This node is used to create OmniLayer groups from geometry, layer name and material inputs. Multiple OmniLayer groups can be created and wired into a OmniGrasshopper Component to be published.

OmniLayer Module Properties

Input

Geometry

G

Geometry to be converted to OmniLayer for publish (live sync / send to view)

Input

Layer Name

LN

Name of the OmniLayer group

Input

Material

M

Material/Color input to be assigned to the OmniLayer group

Output

OmniLayer

OL

Object group with layer name and material

Important

Geometry input always needs to be flattened. If OmniGrasshopper turns red and states “item with the same key has already been added”, try flattening the geometry input to OmniLayer.

Note

Material can be set with OmniMaterial, Color Swatch or a named color/valid material name using the Panel input. The list of color names accepted mimics the HTML5 named color list found here HTML5 Color List

OmniBrowser Component

The OmniBrowser allows additional workflow possibilities by giving access the OMNIVERSE® Server browser. Only one browser node per canvas is allowed.

Typical Workflow Capabilities added by this node

  • Sign in to a server

  • Link to previously saved child USD file for Live Sync

  • Manually override server (Server override will take priority over the Server Sign In button)

Output

Project Folder PATH

P

Output

FN

OmniMaterial Component

This node is used to select materials with a dropdown list. The dropdown list is looking into the CSV Mapping File for Grasshopper which can be located in the following directory <Documents>/Omniverse/Grasshopper/omniverseMDLtable.csv

Note

One OmniMaterial per OmniLayer group can be assigned.

Connecting Models for Output

Using the OmniLayer Component (node) in Grasshopper allows you to convert geometry to OmniLayer group through the geometry input on the OmniLayer Component.

../_images/connect_rhino_grasshopper_connect-models.png

In the above example, notice how geometries need to be wired through OmniLayer, OmniGrasshopper does not directly accept a geometry input.

Note

If any geometry is created and NOT connected to the OmniGrasshopper Component using the OmniLayer node, it will not be output in the final result to the Omniverse.

Exporting Grasshopper Data to the OMNIVERSE®

In order to send data to the OMNIVERSE®, you must first establish a connection to an NVIDIA Omniverse™ Nucleus server. This is generally done through the Omniverse Login Menu in Rhino.

Publishing Grasshopper Data on the OMNIVERSE®

Assuming you already have OmniLayer group connected to OmniGrasshopper Component and that you are connected to either your localhost server or another OMNIVERSE® Server on your Network, the next step is to publish. To do this, we will simply click the “Publish” button on the component.

../_images/connect_rhino_grasshopper_publish-1.png

In the below image, notice the dashed lines connecting the geometry input to OmniLayer node. This means a data tree is coming through the connection, we need this to be a flat list. To flatten this data, right-click on the input node Geometry item and select Flatten. The output should now be represented as a solid line.

../_images/connect_rhino_grasshopper_publish-2.png

Now we are all set and ready for publishing.

To start the publishing operation, simply click the “Publish” button on the component.

Browse and select where you would like your project to be saved, give your project a name and click Publish to complete the operation.

../_images/connect_rhino_grasshopper_publish-3.png

Note

Project Folder PATH: (optional) accepts a panel input, used to override the project path selected at the publish dialog box. As long as an input sting is defined the dialog box is skipped during publish - format: /Users/yourUserName/yourProjectName

Sending Grasshopper Models to NVIDIA Omniverse™ View

Sending to NVIDIA Omniverse™ View is virtually the same process as Publishing. Once again it is assumed that geometry is connected to the OmniGrasshopper Module and that you are already connected to a localhost Server or Network Server.

Using Grasshopper in Live mode

Live mode is available whether Publish or Send To View. To enable live mode, simply Export using either Publish``or ``Send to View, then enable Live Sync on OmniGrasshopper Component. While ON, your model will update in realtime and can be viewed / managed in realtime by other OMNIVERSE® apps.
