Short: Geiss/G-Force like plugin for AmigaAMP (68K) Author: Thomas Wenzel (68K port by SuRgEoN) Uploader: SuRgEoN (christian michael groenjord dk) Type: mus/play Architecture: m68k-amigaos VBCC compiled 68K-port of Thomas Wenzel's cool Subspace-plugin for AmigaAmp. Background story: I wanted a good looking plugin for my recently acquired Mediator/Voodoo3. Subspace was the most interesting open-sourced non-W3D plugin I could get my hands on. Unfortunately it is also very demanding with respect to cpu and bandwidth to gfxcard. Minimum requirements: - AmigaOS 3.1 - full 68060 (66MHz is strongly recommended) - fast gfxcard (Mediator1200 with Voodoo3 will do just fine) - Picasso96 2.0 or CyberGraphX v3 - 320x200 or 320x240 8-bit screenmodes Performance: (tested with Blizz1260/66 and Mediator1200/Voodoo3-3K, latest mmu driver) Using medium quality audiodecoding, freqdiv 2 and optimised prefs/settings (see below): Subspace_68k_LO version (240x112) 11 fps Subspace_68k_MED version (272x144) 8 fps Subspace_68k_HI version (288x176) 6 fps Subspace will probably not look good on anything less than a 66Mhz 060, sorry. How to achieve highest stable framerate for Subspace plugin with AmigaAmp-Prefs: - set play buffer to 1/10 second - loadbuffer should be "file" to eliminate HD access - task priorities: main=1, play=1, vis=0 (note: side-effect is that you can not change settings while playing) - decrease the audio quality (freqdiv: 2 or 4, quality: medium or low). (note: the plugin should be run at 0 priority with AmigaAmp setup like above) - choose backdrop and immovable mode (from menu), then save settings. Notable changes from PPC/WOS version: - Picasso96 supported! - Screenmode Requester (320x200 or 320x240 8-bit modes) - 'T' key toggles song-title display (default on) - 'L' key locks/unlocks current waveshape/deltafield combination - static palettes (palette randomizer produced ugly results too often) - some ugly waveshapes left out. - 3 versions: 240x112, 272x136 and 288x176 centered on 320x200 screen - tooltype support is missing, hence the 3 versions - source adapted for VBCC (it looks a quite messy:) History (68k version) - first release Future: - make it amplifier compatible - aspect correction for 320x200 screenmode - maybe add AGA support Thanks: Thomas Wenzel for AmigaAmp and for open-sourcing for this cool plugin! Original readme from Subspace: ------------------------------ Homepage -------- http://amigaamp.amiga-software.com History ------- v1.0 - initial release v1.1 - more warpfields - more waveshapes - more colormaps - experimental PowerUP version Legal ----- Copyrighted Open Source Freeware. All restrictions and distribution conditions of AmigaAMP apply. Based on and inspired by G-Force for WinAMP. Don't ask me too many things about the PowerUP version! Running several PowerUP tasks at different priorities is very unstable on my system, so I decided to use WarpUP which is much more reliable here. However, some people have reported the contrary, so it's worth a try. If it doesn't work - bad luck. If it hangs - bad luck. Don't bother me :) Usage ----- Just start the plugin while AmigaAMP is running in skin mode. For the PowerUP version to run smooth don't set AmigaAMP's PPC decoder priority to anything higher than 0. Key assignments --------------- ESC - quit F - show framerate on/off W - show waveform on/off I - show info about program on Options/ToolTypes ----------------- RESOLUTION - LOW = 320x240, HIGH = 640 x 480 SCREENSIZE - Override default vertical screen [25 .. 100] in percent MAXFPS - Limit framerate to the number specified Example ------- RESOLUTION=HIGH SCREENSIZE=50 MAXFPS=10 Minimum requirements -------------------- AmigaOS 3.1 CyberGraphX v3 PowerPC 603e or 604e (PowerUP AND WarpUP supported!) Fast graphics card (Z3, PCI or Local Bus) More info --------- See AmigaAMP's documentation The framerate heavily depends on the throughput of you graphics bus. A CyberVisionPPC along with a PPC604e-200 will give you about 20fps in low resolution/full size and 10fps in high res at 66% screensize. Everything less is probably slower. It may be nessecary to select at least 1/5s playback buffer in AmigaAMP for uninterrupted playback. Future plans ------------ - More Waveshapes and Warpfields - Particles - Minor speed optimizations
