The Sketch-a-Graph can enlarge or reduce pictures. * Click through the introduction pages * Position the cursor/tracer inside the large rectangle ready to trace (full screen makes tracing easier) * Click to start tracing and drawing * Click again to stop tracing and drawing (Green Flag if you want to start again) You can create a new backdrop with a different picture to reduce.
The Sketch-a-Graph is a toy made in the 1960s that can be used to enlarge, reduce or copy drawings. Enlarger: https://scratch.mit.edu/projects/246913552/ Copier: https://scratch.mit.edu/projects/969829218/ There is a Math Sprite inside the project showing the trigonometry and geometry that I used. The tool was known long before the Sketch-a-Graph toy and is also called a Pantograph. https://en.wikipedia.org/wiki/Pantograph Testing Tags: #Art #Art #Art #Art #Art #Art #Art #Art #Art #Art #Tutorial #Tutorial #Tutorial #Tutorial #Tutorial #Animation #Animation #Animation #Animation #Game #Game #Game #Game #Game #Game
