Hi,
Just as part of easing into pyglet and opengl, I am wondering if anyone
can explain the following line of code:
https://github.com/pyglet/pyglet/blob/5bc0f80e0446bc4ebb2b381370802f60320c0d8a/pyglet/shapes.py#L1178
Where it seems like 2 of the 4 corners of the rectangle repeat on the
array. I just wanted to experiment making a rectangle shape with rounded
corners by using bezier curves on the corners and would be happy to
learn why opengl is being sent 6 points here.
A rectangle is made of two triangles:
D--C
| /|
|/ |
A--B
The vertex list has 3 points for each triangle: A,B,C, A,C,D.
If you're just starting out, I recommend trying a straight-edged shape
(a trapezoid, for example) before moving on to curved corners :)
Also in case you have any thoughts or suggestions about sizing such a
rectangle to wrap around text such that adjusting the edges of the box
to fully contain the text glyphs (or sizing the glyphs to match the size
of the box can be accomplished). This is towards making text areas
nicely surrounded by a shape. The current button implementation under
`gui` seems to use an image instead.
Look at TextLayout's content_width and content_height:
https://pyglet.readthedocs.io/en/latest/modules/text/layout.html#pyglet.text.layout.TextLayout
Classes like Label inherit these from TextLayout.
