Added CircleSource, QuadSource, BrickSource and SyphonSource. The SyphonFBO is disabled since it would not run on rpi. [OSX only] For Syphon to work you need to install ofxSyphon addon and add "ofxSyphon" to the addons.make of ofxPiMapper. Then uncomment all the syphon lines in the code. So far the SyphonClient will choose the first Syphon source presented to him. ( You might want to start the server later ).
FBO Sources Example
This example shows how to use custom (FBO) source functionality with ofxPiMapper. Below you can see a list of custom sources and feel free to add your own via pull requests!
- ScanlineSource
- SlideShowSource
To build your own source, one should start by extending the FboSource class. When the source is ready, it should be instantiated in the ofApp class and passed via mapper.registerFboSource(...source) function before the mapper.setup() call. This will make the source name to appear under FBO Sources category in the source selection mode.
Look at the source code of the custom sources to understand how to build one, but essentially it is extending the FboSource class of ofxPiMapper and overriding the setup(), update() and draw() functions.
In the setup() function you should set a name for your custom source.
name = "Name Your Source";
Then you should set the dimensions of your source by using the allocate() function.
allocate(500, 500);
In the draw() of your custom FboSource you should decide whether you want the previous frame to be cleared from the gfx buffer or not. If you want to draw a fresh frame, use the ofClear() function.
ofClear(0); // Clear with black
