Q1: What is projectM?
|
|
--------------------
|
|
A: projectM makes pretty pictures from music in realtime.
|
|
Specifically it uses iterative image-based rendering techniques which
|
|
are hardware accelerated via OpenGL. projectM was developed with
|
|
cross-platform support in mind, using SDL and OpenGL. The only port
|
|
right now is Linux/XMMS, but it should be easy to plug-in to other
|
|
music players on other platforms (even windows and Mac OS X).
|
|
|
|
projectM aims for compatability with MilkDrop's latest release (1.04b at
|
|
this time), but we have always intended to surpass it. This program was
|
|
inspired by Ryan Geiss' wonderful program MilkDrop. www.geisswerks.com
|
|
|
|
Q2: What? This preset doesn't look like it does on Milkdrop.
|
|
-----------------------------------------------------------
|
|
A: We know. Some of the simple waveforms (1,2,3,4,5) are not even close to
|
|
correct. They are similiar, but not exactly the same. Also, the solarize,
|
|
brighten, and darken filters aren't done yet either.
|
|
|
|
Sometimes things just don't look right because we might, for example, draw
|
|
shapes a tiny bit too big or small. Small errors propagate and become HUGE
|
|
after a few manipulations. But who knows because it takes forever to tweak
|
|
things like this.
|
|
|
|
Q3: Where can I get more presets?
|
|
--------------------------------
|
|
A: www.milkdrop.co.uk is a great place to start. However, all their
|
|
presets are packaged in self-unzipping .exe's for win32. I
|
|
extracted them with wine and it worked wonderfully.
|
|
|
|
Check out the milkdrop forums at www.winamp.com to find new presets
|
|
daily. The URL is below

|
Q4: What are the system requirements?
|
|
------------------------------------
|
|
A: To run projectM you need a Linux system w/a sound card and a video card
|
|
with OpenGL hardware acceleration. We find that projectM runs MUCH better
|
|
with the 2.6 series kernel and ALSA sound.
|
|
|
|
What does that mean? Well...
|
|
|
|
projectM has only been tested prior to me writing this on 4 computers.
|
|
|
|
All those computers used some form of Redhat (8,9, & Fedora 1),
|
|
although this should make no differance if you run a differant distro.
|
|
|
|
Also, all of them used Nvidia (Geforce 3 Ti200, Geforce 4 MX440 & Ti4200)
|
|
|
|
WE STRONGLY RECCOMEND THE USE OF ALSA AND THE 2.6 SERIES KERNEL
|
|
|
|
Q5: Why is projectM so slow!!!
|
|
-----------------------------
|
|
A: If projectM is slow for you all the time, and not just on a select few
|
|
presets, you can try lowering the rendering quality, and this will speed
|
|
things up A LOT. To do this, lower the texsize and gridsize (gx,gy) in
|
|
/etc/projectM/config
|
|
|
|
Texsize controls the size of the rendered image. If you think your video
|
|
card is too slow or doesn't have enough memory, then change this. A middle
|
|
value for texsize is 512. 1024 is nice looking, and 256 is for VERY slow
|
|
computers.
|
|
|
|
If your processor is the bottleneck, then lower gx and gy. gx and gy
|
|
control the size of the interpolated per-pixel mesh. 24/18 is a low-middle
|
|
value. I run at 48/32 some times on my Athlon 64 3200, and I could
|
|
probably go higher, although some presets slow down for me at this VERY
|
|
high setting.
|
|
|
|
Certain presets can be processor hogs and slow the framerate down to
|
|
almost 0. In this situation my best advice is not to use those presets.
|
|
All the presets that come with projectM should be slim enough to run on
|
|
nearly all machines capable of running projectM in the first place.
|
|
|
|
Q6:How can I increase the rendering quality to make projectM look better?
|
|
-------------------------------------------------------------------------
|
|
A: Read Q5 and do the opposite!
|
|
|
|
Q7: How can I configure projectM? (where's the config file?)
|
|
------------------------------------------------------------
|
|
A: /etc/projectM/config
|
|
|
|
Q8: Where are the presets?
|
|
--------------------------
|
|
A: /etc/projectM/presets
