Mesh Attributes

App: apps/mesh_attributes/

A single triangle with per-vertex animation: each vertex’s position (px, py, pz) and color (r, g, b, a) are updated every frame via setVertexAttribute. Also shows a small GUI (window size, “Log” button) and terminal commands (help, reload) using #!command.

Run from root

% ./plume3d mesh_attributes

or

Run from app directory

% ./../plume3d .

What it does

• Mesh — Three vertices; in update, vertex 0: animate X and red; vertex 1: Y and green; vertex 2: Z, blue, and alpha. No explicit flush() in this app; add _mesh.flush() after attribute updates if your backend requires it for dynamic data.
• GUI — Window with current width/height and a “Log” button that logs mouse position with Logger.info.
• Terminal — #!command(description = "Print help message") help() lists commands (help, reload).

APIs

• Graphics — loadShader, newMesh, drawMesh.
• Mesh — setVertexAttribute (e.g. "px", "py", "pz", "r", "g", "b", "a").
• Gui — beginWindow, layoutRowDynamic, label, buttonLabel, endWindow.
• Window, Input, Logger.
• Terminal: #!command on Game methods.
