To prepare a file for the online viewer, first get an access token
with the data:read and data:write scopes.
resp <- getToken(id = Sys.getenv("client_id"), secret = Sys.getenv("client_secret"),
scope = "data:read data:write")
myToken <- resp$content$access_tokenNex, encode the urn using the jsonlite::base64_enc()
function.
Then, translate the file into SVF format:
To check the status of the translation process:
Finally, embed the urn of the file in the viewer, which is described in the Viewer section.
To extract data from a file, follow the steps in the previous section
for getting a token with the data:read and
data:write scopes, encoding the urn of the
file using the jsonlite::base64_enc() function, and
translating the file into SVF format using the
translateSvf() function. Next, retrieve metadata for a file
using the getMetadata() function, which returns an object
with the type, name, and guid of
the file. Note the guid and store it in
.Renviron.
resp <- getMetadata(urn = myEncodedUrn, token = myToken)
myGuid <- resp$content$data$metadata[[1]]$guidTo get the object tree of a model, use the
getObjectTree() function.
To extract data from the model, use the getData()
function.
AutoDesk provides a WebGL-based viewer for rendering 2D and 3D
models. To use the viewer, make sure to first follow the instructions in
Prepare a File for the Viewer above. Then simply pass
the urn of the file and the token to the
viewer3D() function:
The viewer can also be embedded in Shiny applications, interactive R
markdown documents, and other web pages thanks to the Shiny Modules
framework. Here is a simple example of a Shiny app and the
viewerUI() function:
