In this sample, you could find how to query the available avatar computation/export parameters, create an avatar computation task, poll its status and download avatar export files using JavaScript.

You will need to complete the following steps before experimenting with this sample:

• Get AvatarSDK developer account at https://accounts.avatarsdk.com/developer/signup/
• Create an application with Client credentials Authorization Grant at https://accounts.avatarsdk.com/developer/
• Copy client_id and client_secret from the Client Access application at https://accounts.avatarsdk.com/developer/

Now you are ready to go:

• Clone this repository to your computer
• Run serve.sh script to start a simple web server (requires python3 installed) and navigate to http://localhost:9000
• Fill client_id and client_secret fields with the corresponding values from the Developer page above and click Authorize button
• See running requests in your browser developer tools

asdk.js wraps API calls, since every request must include Authorization header. It also parses JSON responses and handles request errors. Every AvatarSDK method returns a Promise

avatars_ui.js wraps UI/UX. It initializes AvatarSDK and then:

• build avatar computation and export parameters forms dynamically, based on API response (see fillParametersGui and fillExportParametersGui)
• visualize selected parameters (see generateComputationParameters and generateExportParameters)
• generate additional export parameters for avatar visualization, based on the selected export parameters (i.e. predefined format and textures parameters and the first asset from haircuts/outfits. See generateVisualExportParameters)
• create and poll avatar computation task (see onComputeAvatar)
• visualize avatar (see visualizeExport)
• build available export files form (see fillExportsGUI)
• download export files (see downloadExportFile)

avatars_gl.js wraps 3D rendering. It initializes the rendering scene, controls, and adds avatar model into the scene properly (i.e. adjust some material properties, see _adjustMeshProperties). Please note: only GLB with embedded meshes and textures are supported now, so we add the second group of export parameters to request this format of mesh simultaneously with the user-selected ones (see generateExportParameters at avatars_ui.js).

main.js wraps authorization UI/UX. Please see the note on authorization below.

This sample uses the following libraries:

• lil-gui for the GUI
• three.js for the 3D
• JSZip for ZIP archives handling

Avatar SDK WEB API uses OAuth 2.0 for authorization. The authorization token retrieval form is present here purely for the sample purpose. Production code must keep client_id and client_secret secret, perform authorization on the server-side and provide frontend only with access_token (i.e. pass the token within config into avatars_ui.js :: init(config) call).
