Install compiled version of GL.framework (also Intel only)
Version 0.1 Released Dec 14th 1997
Intel only version.
What is ScreenDoor.app?
ScreenDoor.app is a BackSpace.app replacement application. I wrote it because I was sick of BackSpace taking up a spot on my Openstep Doc, and I wanted an Openstep app that I could write OpenGL screen saver bundles for. I didn't feel like porting BackSpace.app to Openstep, so I wrote my own screen saver. It's now been ported to Rhapsody.
Why ScreenDoor instead of BackSpace?
1) ScreenDoor uses no icon space. ScreenDoor has OpenGL bindings. ScreenDoorViews are pretty easy to write. I threw this together because I thought BackSpace really neede to be updated. If you like it I'll do more with it. If you don't, then it was a good learning experience for me.
What does it come with?
5 .tar.gz files
GLFramework.I.tar.gz - Intel compiled version of the Mesa GL framework
OpenGLViews.0.1.I.tar.gz - the Intel compiled versions of the OpenGL screensavers
ScreenDoor.0.1.I.b.tar.gz - the app itself
ScreenDoorViews.0.1.I.tar.gz - the standard views listed below
ScreenDoorViewSource.tar.gz - the source that I talk about below (not the full source yet.)
ScreenDoor.app is a beta application. If people like it I will make it a full app and probably release the source. ScreenDoor binds to the GL.framework (from the Mesa distribution) and I will provide a copy of that as well (in compiled format). You have to have this framework in order for ScreenDoor.app to run. Place this framework in ~/Library/Frameworks or in /LocalLibrary/Frameworks. Place the ScreenDoorView bundles in ~/Library/ScreenDoorViews or in /LocalLibrary/ScreenDoorViews. This distribution comes with 6 screen savers.
1) BlackScreenView.screenDoorView : Just that, a plain black screen - however this is an example of a static screen door view.
2) SpaceView.screenDoorView : Guess what, we have stars - just another star view.
3) BoinkView.screenDoorView : The standard bouncing ball view from Nextstep
4) OpenGLMorphView : sorta like the morphing objects on NT/95
5) OpenGLPlaneView : OpenGL paper airplanes flying in circles
6) OpenGLWaveView : A checker board waving in the wind - kind neato
The source is provided for 1), 2) and 4) to give people an idea of how to create a screenDoorView. More views may be on the way, but I have a lot of projects and not a lot of time - if people really like or want this - I'll add a bunch more.
A note on the OpenGL stuff:
SLOW, SLOW, SLOW - I'm no OpenGL programmer, I just think the stuff is neato. I have provided a method by which you can pop the stuff up on the screen, but right now I'm re-drawing the entire screen with each draw command. I have enclosed the OpenGLView.m file which is the basis for the drawing. If you can speed it up, or have any ideas as to how I can please let me know. Graphics ain't my thing. If they are yours please let me know.
How do I write a screenDoorView?
1) Look at the provide sample source
2) Create a bundle project (or copy one of the others)
3) Make sure that SaverView.h is included (and OpenGLView.h if this is an OpenGLSaver) and just draw what you want in your drawRect: call. My oneStep calls are a throwback to the old BackSpace.app.
4) Start coding.
In the future I would like to create a user level application for creating screen savers. Once again, if people really want it I will do it.
I ran ScreenDoor.app and the icon disappeared, what's up?
That's the point. There is no icon. The first time you run the application the hot spot defaults to the upper right hand corner. Just move your cursor up there and click in the corner. A control panel should pop up. From there you can select your screen door view. The application won't run if you haven't installed the views in the correct places. The little monitor allows you to click in it's corners to set the hot spot location. The SpaceView is the default screenDoorView.
I'm having problems/questions/suggestions, who do I bitch to?
Me, epeyton@cmg.fcnbd.com. I'll probably respond, but I am very busy and it might take some time.
