Hi. I've been meaning to have a play around with the new AppGameKit plugin system for a while now, so I thought I'd start with a very small plugin that just adds support for multiple render targets to AppGameKit. You can download the initial release
here from GitHub.
The download above includes the binaries for Windows, macOS, and Linux, as well as some documentation of the commands provided and an example program, so hopefully it should be straightforward to use.
The basic idea of the plugin is to allow you to write to multiple render images from a single fragment shader. This can be useful for lots of different rendering techniques. To do this, the plugin provides a SetRenderImage command to allow you to bind a render image to a specific attachment point. To start rendering to your render images, you can then use the SetRenderToMRT command, which is analogous to AppGameKit's own SetRenderToImage and SetRenderToScreen commands.
This is just a first release, so I'd be keen to get some feedback on it. If you fancy giving it a try, do let me know how you get on with it, and feel free to report any bugs or make suggestions about how it might be improved. All the code is available on GitHub too, and I'm open to pull requests if you feel like changing something yourself!
