Free 3d screensavers software for linux

Really Slick XScreenSavers project is a GLX port of the Really Slick Screensavers collection by Terry Welsh.

The screensavers can be installed as standalone programs or as XScreenSaver hacks.

Really Slick ScreenSavers GLX Port is a port of some nifty OpenGL screensavers that were originally written for Windows to GLX.
Really Slick ScreenSavers GLX Port is intended for use with an existing screensaver daemon like xscreensaver.
Enhancements:
- This release fixes minor bugs exposed by newer compilers and libraries.

frob 3D viewer project is a 3D object point/wireframe/polygon viewer - called frob3dv for lack of a better name.

I wrote this version mainly to learn c++. Also it was the first program I wrote after I got a PC (and put linux on it), but it has a long history. Many years ago I wrote a few stacks in Hypercard (on a Mac SE) for editing and displaying 3d shapes. I then ported it to modula-2 , using the free MacMETH compiler, then MOPS, a great free object-oriented programming language and application framework for the mac.

That is where it got most of its current class hierarchy. At that stage it was still only a wire-frame viewer. I then ported it to c++ for the macintosh using the Macintosh Programmers Workshop. When I wiped Windoze off my PC and put an operating system (linux) on it, I ported it to X and added the polygon drawing.

3D Pong project is a simple Xlib vector-based ping-pong game.
3D Pong is is a very small and fast ping-pong or handball game for one or two players. It uses simple 3D vector graphics in Xlib.
Multiple views are possible, and red/blue separation is available for users with 3D movie glasses.
Main features:
Game Play:
- 1 player against the computer
- 1 player in "handball" mode
- 2 players, networked
- User-defined gravity level
- With or without a deflective "net"
Display Modes:
- Red/Blue split mode for true 3D using 3D glasses!!!
- Six viewing positions:
- First Person POV from behind your paddle
- "Bleacher" view from the side of the game arenta.
- Above view.
- Freely rotatable mode (using the mouse)
- A dizzying "follow the ball" mode
- Follow the paddle mode

XInvaders 3D project is a 3D Space Invaders clone for X11.

You are a lone star fighter facing endless waves of space aliens. Your sole objective is to shoot down as many aliens as you can.

3D Spatialization of Sound is a Linux/X11 port of the 3D spatializer library from the CRC.

This program creates "directional" stereo sound from mono source. CRC folks told me I shouldnt have raised the sampling frequency without adjusting other stuff.

Oh well. This was a proof-of-concept type project anyway. I think to get correct 3D effect, you need to drop sampling rate back to 11025.

To Build the X11 implementation:

1. make
2. cp audio-filter /usr/local/bin
3. mpg123 -m -s some_music.mp3 | audio-filter | aplay -S -s 44100 -f s16l -

audio-filter is implemented as a filter, it reads signed 16 bit mono input at 44100 khz from stdin, and outputs signed 16 bit stereo, 44100 khz output to stdout. You can replace mpg123 with any sound source generating signed 16 bit 44100 khz mono signal. "aplay" is a sound player utility which comes with ALSA linux sound driver. You can use "play" from the sox package, or "ampctl", or any other sound player that would read 44100 khz, signed 16 bit stereo raw data from stdin. For "sox" play script, you would replace "aplay" command line with "play -c 2 -f s -r 44100 -s w -t raw -"

If everything is good, a 640x480 window will come up, with some cryptic writing on the top, a filled circle with an arrow pointing right, and a empty circle slightly to the right of the circle with arrow.

NOTE, that just like in the original Windows implementation, the axiss are reversed. The arrow on the "head" is pointing "forward". So, in the default startup configuration, the sound is located in front of the listener. Moving the sound source "up" moves it to the left of the listener, and "down", to the right. You can visualize this well if you turn your monitor 90 degrees counter
clock wise.

The filled circle with an arrow is your "head"
The empty circle is the "sound source"

You can move the "sound source" around by clicking the mouse at any position in the window, or by clicking on the "sound source" circle, and dragging it to the desired position. Soundfield will be dynamically updated as you do this.

You can move the "head" by moving the mouse to desired position, and right-clicking. The "head" icon will move to the new position and soundfield will be updated.
