Make sure to describe what I should be working on :)

Whiteboard HyperCard ~ live collaboration/drawing/chat/whiteboarding

Easiest installation through toltec's opkg

opkg update && opkg install whiteboard-hypercard

Self-hosting whiteboard-server / hosting private rooms

On a machine with IP 1.2.3.4 reachable over the Internet, run:

git clone https://github.com/fenollp/reMarkable-tools.git && cd reMarkable-tools && make debug

Now on your tablet, run the whiteboard Rust application with --host, as in:

export WHITEBOARD_WEBHOST=http://1.2.3.4:10001/screenshare
.../whiteboard --host=http://1.2.3.4:10000

Finally, docker compose should show you something akin to:

HyperCards

Visible rectangular elements that can be drawn on/dragged/zoomed/rotated/connected/duplicated.

  • tools / modifiers are square cards snapping to the edges of the screen
    • henceforth mentioned as [ToolX] for tool X
    • using them / modifying them by a press held while using the pencil * similar to Minecraft's mix & match: action through combination
    • a [?] tool always hangs in a corner, pressing = shows description text (like crosswords)
    • modification (reorganization / addition / removal) through drawing and pressing
    • tools icons can be drawn too / loaded from a font / loaded from a builtin set of images
    • pen & fingers are different devices for different purposes
      • => drag/move and pinch/zoom (think Apple trackpad gestures) not a pen thing
  • whiteboard card
    • rectangle that can be moved by dragging on the edges
    • zoom/rotation by dragging in the area (not the edges)
      • MIGHT: zooming hard moves to another user's view? --> canvas is a window/camera view that can move in 2+1D
    • some bi-directional communication with a networked service
      • user joins a room and shares their live drawings
      • It is possible to combine a [Selection]-ed group of strokes and [Digitize] to ask service for translation
  • [Digitize]
    • connects to a distant machine or achieves its AI inference on-tablet
    • takes a few strokes in and outputs text+area / shape+area
  • [Selection]
    • draw approximately on one or more strokes
    • creates a group that can be used with other modifiers
    • press another tool before unpressing this one to pass the group to the other tool
  • [Image]
    • add an image to a layer
      • should be able to dim that layer
    • select the tool's image with [Setter] > [Image] --> opens image picker
    • image should be draggable + zoomable (= two-finger gesture on iOS Reddit app's image viewer)
      • should be able to draw on top of said image
