Painless 2D vector graphics, animations and simulations.

gloss

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

• Home page and bug tracker are on a separate site.

Example

Getting something on the screen is as easy as:

import Graphics.Gloss
main = display (InWindow "Nice Window" (200, 200) (10, 10)) white (Circle 80)

Explore and run the example projects using stack:

$ stack setup
$ stack build
$ stack exec gloss-boids

Usage

Once the window is open you can use the following:

• Quit

  • esc-key

• Move Viewport

  • arrow keys
  • left-click drag

• Zoom Viewport

  • page up/down-keys
  • control-left-click drag
  • right-click drag
  • mouse wheel

• Rotate Viewport

  • home/end-keys
  • alt-left-click drag

• Reset Viewport

  • 'r'-key

More

• Animations and simulations can be constructed similarly using the 'animate' and 'simulate' functions
• Games with user input can be constructed with the 'play' function.
• See the gloss-examples package for more.

PULL REQUESTS

As Gloss is now fairly stable, I typically make releases only when there is a new GHC version. If you have added a new feature or fixed a bug, and want your pull request merged sooner than that, then send email to benl AT ouroborus.net. I don't pay attention to github notifications, but am happy to receive emails from people. If you have changed any internal functionality then please test that all the gloss-examples still work before submitting your pull request.

If you just want to bump a dependency version then get a Hackage trustee to edit the package information directly on Hackage. You don't need to raise a pull request here.
