Issue by shiffman Thursday Mar 14, 2013 at 02:07 GMT Originally opened as https://github.com/processing/processing-web/issues/74

keeping track of a list of examples i am continuously asked for by students and remaking. considering creating / including for 2.0.

. noise wave 2D water . simple easing lerp demonstration . morph one polygon to another (with lerp) . how to do keypresses properly with boolean set to true in keyPressed, false in keyReleased

For keypresses I just added something to:

@REAS can you take a look at this example? This comes up a lot for me in class, how to "morph" one shape into another by lerping between vertices. I think @blprnt does this a lot in his examples.

I need to add comments still.

I think it's great to add. Do the circle and square need to have the same # of points? If so, I think it's better to use arrays of PVectors (PVector[] circle;) instead of ArrayList and to make it clear in the comments. Also, to follow the style for examples, please always use braces:

if (state) { v1 = circle.get(i); } else { v1 = square.get(i); }

Thanks @REAS This particular example does require the arrays to have the same number of points. The reason I choose an ArrayList, however, is that filling the list of vertices does not involve a simple counting loop and it's much simpler to calculate the vertices and just call add(). I'll try to make this all clear in the comments and will revisit if necessary.
