ofxSceneManagerGui

OpenFrameworks addon to manage scenes using an ensemble of ofxGui params. It works great in combination with ofxTransitionSlider.

Params

• startTime: time in ms of when scene needs to start
• name: name of the scene, it is print on the gui
• autoStart: if it true the scene starts automatically, if false the scene manager stop and you need to start manually.
• infinityTime: if true keep the current scene until you press the key to go to the next scene.
• transitionTime: time of all ofxTransitionSlider for that scene.

Consideration

For now, you have to create main scene manually, the scene manager allows you to generate only (sub) scenes using the keyboard. This could be improved in the future.

Examples

exampleSceneManger

A simple example to understand how to use the scene manager and how to organize files.

• exampleSceneAudio - TODO
• exampleSceneManagerGui-TransitionSliderFrameBased
• ofxSceneManagerGui-TimecodeLTC

Usage - SceneTime

The time (play) can be managed in 3 different modes:

• (default) ofSystemTimeMillis it uses the system time

• FrameBased it ignores the time, but using the number of frames from a scene and another one. This is useful if you need to export a movie and your app has not have a constant framerate

• ExternalTimeMillis it uses an external value to manage time. For example using timecode to control the scene time.

We tested to pass from ofSystemTimeMillis and FrameBased at runtime. Using ExternalTimeMillis it is better to start the application in this mode (otherside behaviour is undefined).
