Generate a Mesh from an Image (Rutt/Etra)

This would be a great feature, being able to generate a 3D mesh geometry from image/video. Similar to Rutt-Eta.

Proposed nodes

(Mockup by Team Vuo.)

Team Vuo proposes adding 3 nodes:

• Make Grid Mesh — Outputs a mesh with one of the following types:
  • Horizontal Lines — outputs a line strip for each row (equivalent to v002's "Scanlines" mode)
  • Vertical Lines — outputs a line strip for each column
  • Square Outlines — combines Horizontal and Vertical Lines, producing square outlines where each corner is a cell (equivalent to v002's "Square Mesh" mode)
  • Triangle Outlines — combines Horizontal and Vertical Lines, producing pairs of triangle outlines where each corner is a cell (equivalent to v002's "Triangle Mesh" mode)
• Make Grid Point Mesh — Outputs a mesh with a point for each cell (equivalent to v002's "Points" mode)
• Displace Mesh with Image — Moves the vertices in the input mesh based on the brightness of the input image.

...and modifying the existing Make Square Vertices node to allow selecting how many rows/columns to output.

(In Vuo 0.8.0, we're planning to rename the existing "Vertices" type and ports to "Mesh", for clarity.)

Here's an example of using these proposed nodes:
