This PR adds a `StudioMode` resource to toggle editing capabilities, and
configures the frontend application to read the desired mode from a URL
parameter.
For now, setting the app to `StudioMode::Viewer` with
`<app-url>?mode=viewer` hides the Transform Toolbar and disables most of
the interactive features of the app, but otherwise exhibits the same
behavior as `StudioMode::Editor` / `<app-url>?mode=studio`.
In the future, the "Viewer" and "Editor" modes will receive different
initialization inputs to better serve the needs of their use cases. In
particular:
* The "Viewer" mode will accept a BVH animation handle, which should be
played in a loop on a simple mannequin asset, allowing a user to preview
a given animation before using it within the full studio workflow.
* The "Editor" mode will accept a full Bevy scene handle which can be
edited and saved to the user's account. These scenes will serve as the
basis for the generative-AI workflows Storyteller Studio is ultimately
seeking to facilitate.
* It will likely be useful for "Editor" mode to alternatively accept
only a BVH animation handle, which would be used to initialize a new
scene for editing similar to "Viewer" mode, but with editing
capabilities enabled.
This PR does some rudimentary cleanup / reorganizing to the
`studio-frontend` project.
### Changes
* Refactored `studio-frontend` to use the `<sts-canvas-provider/>` and
`<sts-viewer/>` components from `studio-web`
* Added some CSS layout utilities for positioning overlayed UI elements
* Extracted `<sts-toolbar/>` and `<sts-toolbar-group/>` to their own
components
* Extracted `<sts-transform-toolbar/>` to its own component
* Add plugins for `wasm` and `top-level-await` to Vite config
* Avoid bundling dependencies
* Add external dependencies to project-level `package.json` manifests
This PR adds a `CanvasProviderElement` to `@storyteller/studio-web` to manage
the complexity of maintaining a single concrete `HTMLCanvasElement` for
`@storyteller/studio`, while still being able to treat components like the
`ViewerElement` as self-contained "views" that behave as expected with regards
to CSS styling, DOM placement, etc.
Consuming applications should wrap the new `<sts-canvas-provider />` element
around some common ancestor of all views into the `@storyteller/studio` app,
similar to a React context provider.
The `react-frontend` application has been updated to take advantage of the new
`CanvasProviderElement` by demonstrating a more realistic use case for the
`ViewerElement`. The new demo presents a grid of "thumbnails," one for each
object in our hard-coded "object library." Clicking on one of these thumbnails
will render a `ViewerElement` for that object in a modal dialog.
This commit implements a Sketchfab-style single-object viewer as a minimal
proof-of-concept.
### `@storyteller/studio-web`
This is a new package to house web components for interfacing with the
`@storyteller/studio` WASM library. It currently includes a single component,
`<sts-viewer />`, which is exported from `@storyteller/studio-web/viewer`.
### `react-frontend`
This is a new application intended as a proof-of-concept and testbed for React
interop with `@storyteller/studio-web`.
Web components are currently a little bit fiddly to use in a React application.
`react-frontend/src/app/studio-viewer.tsx` demonstrates how a React-idiomatic
component can be written as a thin wrapper around a web component, and
`react-frontend/src/app/app.tsx` demonstrates that wrapper component in use.
