4D Draw…
is a simple vector graphics app that lets you draw 4‑dimensional figures. It represents each point's first three coordinates in the usual way, while using color to represent the fourth coordinate.
To create new points…
tap the Add Points button , then drag from the walls to create new points.
To create new edges…
tap the Add Edges button , then tap the points that you want to connect.
To rotate the whole scene…
drag the background (in any mode except Add Points).
To move existing points…
tap the Move Points button , then drag points to move them. Drag a point along its rainbow-colored w‑axis to move it in the fourth dimension. If any two of a point's four axes happen to align on your 2‑dimensional display, you may rotate the whole scene to separate them.
To delete points…
tap the Delete Points button , then tap the points you want to delete.
To delete edges…
tap the Delete Edges button , then tap the edges you want to delete.
