Canvas library

Canvas library OpenSCAD library to project canvas with random images on 3D shapes Howto We must first convert the image to grayscale data using img2gray designed from this thing: https://www.thingiverse.com/thing:3830079. This is the reason why I declare this thing as a remix. The test image comes from clipart-library: Then: ``` $ python img2gray.py penguin.jpg penguin.scad ``` The generated file contains the function levels_penguin(); which gives image data. Sample OpenSCAD file to project the image on a plane: ``` use <agentscad/extensions.scad> use <agentscad/mesh.scad> use <agentscad/canvas.scad> empty = newCanvas( [2,1], [200,100] ); penguin = levels_penguin(); canvas = drawImage ( penguin, empty ); flat = canvas2mesh( canvas ); meshPolyhedron ( flat ); ``` Or projection on a cylinder: ``` ... flat = canvas2mesh( canvas ); // Insert these 2 lines projected = projectCylinder( getMeshVertices(flat), radius=50 ); bent = newMesh( projected, getMeshFaces(flat) ); meshPolyhedron ( bent ); ... ``` Or projection on a sphere: ``` ... flat = canvas2mesh( canvas ); // Insert these 2 lines projected = projectSphereCylindrical( getMeshVertices(flat), radius=100 ); bent = newMesh( projected, getMeshFaces(flat) ); meshPolyhedron ( bent ); ... ``` Documentation Full documentation here: agentscad canvas tutorial
