Take a look of this example and see how it can be done with FILL command and the colour adjustments.

The following examples illustrate the use of repetition in Context Free Art. startshape MyShape path Line1 { MOVETO {x 0 y 0} LINETO {x 1 y 0} STROKE {width .01} } rule MyShape { 36 * {r 10} Line1 {} } startshape MyShape path Line1 { MOVETO {x 0 y 0} LINETO {x 1 y [...]

These exercises cover the use of path in a shape. startshape MyShape path Line1 { MOVETO {x 0 y 0} LINETO {x 1 y 1} STROKE {width .01} } rule MyShape { Line1 {} } startshape MyShape path Line1 { MOVETO {x 0 y 0} LINETO {x 1 y 1} LINETO {x 0 y 1} [...]

We introduce the use of the rotation parameter for a shape: startshape MyShape rule MyShape { SQUARE {x -4 r 90} SQUARE {x -2 r 70} SQUARE {r 50} SQUARE {x +2 r 30} SQUARE {x +4 r 10} }    

After we can create different primitive shapes, we start to combine them together. We cannot simply put all the primitive shapes within one single shape rule, like: startshape MyShape rule MyShape { CIRCLE {} TRIANGLE {} SQUARE {} } Every shape command comes with parameters. We work with the translation parameters x and y to [...]

To prepare for a new course Evolutionary Graphics in AVA, I am testing the use of various graphical tools. One of them is the Context Free Art. It is a ruled based language to generate complex imagery. It cannot be described as a programming language as it lacks a lot of procedural elements. Its recursive [...]
