# Shapemaker

I wanted to dabble in generative art, and, as a first project, create a way to generate small, icon-like shapes from a predefined set of possible lines, curves and circles
18
+
19
+
## A restricted set of shapes
20
+
21
+
![]()
22
+
23
+
Those shapes are described as sequences of elements, such as lines, either straight or curved, that start and end on fixed "anchor points": south-west, south, south-east, east, north-east, north, north-west, west and center.
24
+
25
+
Lines can be grouped to form polygons (with some edges possibly curved), which can be filled with patterns (hatched or dotted) or colors.
26
+
27
+
Additionally, dots, points (small circles) or circles can be added. The latter objects take up a full quarter of the block and can be placed in each quarter's center. These can be filled just like polygons.
28
+
29
+
## A language to describe these shapes
30
+
31
+
I needed a language to describe these shapes with text, so that a program could generate random shapes, while keeping them coherent by reducing the amount of variables needed (randomly generating SVG text directly, for example, is unfeasable).
32
+
33
+
```
34
+
percent:
35
+
top left circle
36
+
bottom right -- top left
37
+
bottom right circle
38
+
39
+
abstract1:
40
+
[ bottom left -- left ) top -- bottom -- bottom left ] filled with green
41
+
top -- right -- bottom
42
+
top left red dot
43
+
44
+
lowercase j:
45
+
center point
46
+
center -- bottom -- bottom left
47
+
```
48
+
49
+
50
+
The idea was to generate SVG from this representation.
