Brillo

Brillo hides the pain of drawing simple vector graphics and raster images behind a nice data type and a few display functions.

<table> <tr> <td> <img src="brillo-examples/picture/Visibility/screenshot.png" width="228" height="235" > </td> <td> <img src="brillo-examples/picture/Tree/screenshot.png" width="153" height="198" > </td> <td> <img src="brillo-examples/images/perspec.png" width="280" height="145" > </td> </tr> </table>

Example

Getting something on the screen is as easy as:

import Brillo

main = display
  (InWindow "Nice Window" (200, 200) (10, 10))
  white
  (Circle 80)

Explore and run the example projects with stack:

stack run brillo-boids
