- Awesome 3D liquid melting action takes over a screen shot of your desktop.
- This screen saver liquefies your desktop by progressively running sin
- functions through it while simultaneously tweaking the color intensity of each
- wave, resulting in a VERY mesmerizing and soothing feeling. Chrome effects
- are also available which will dazzle your eyes, download this saver now!
-
- Saddle up, because this baby uses all of your computers power.รก A PII 350 or
- better is recommended and a 3D accelerator of Voodoo2/TNT power is also
- recommended. This saver was designed on a PII450 w/ Voodoo3 and it can bring
- it to its knees! This is due to the huge polygon counts, and your performance
- will be limited by CPU power and video bandwidth.
-
- This screen saver will leverage the quality of your opengl drivers to the
- extreme. It is entirely NOT fill rate limited on most cards, so pump the
- resolution up to the highest you can. I have identical results on my machine
- (a PII450 w/ Voodoo3) at 640x480x16 and 1600x1200x16, around 22-27fps using
- Preset 1. This is because the frame rate is heavily dependant upon polygon
- processing and throughput rather than fill rate and texturing.

- First, to make sure you have the latest opengl drivers for your video card
- get glSetup at www.glsetup.com.
-
- Unzip the files into your Windows/ directory or if you have WindowsNT
- unzip it into your WinNT/ directory. Get winzip at www.winzip.com
-
- You can also install it by unzipping it into a temporary directory, then right
- click on the .scr file and select install.
-
- To activate it: right click on your desktop background and select properties,
- then select the screen savers tab, this screen saver is called 3D Liquid
- Desktop and should be in the Screen Saver selection box near the top.
-
- If you don't have opengl.dll installed then it won't run, opengl.dll should
- already be installed on windows95b, 98, and NT, if you don't have it then get
- it here: http://www.opengl.org/Downloads/Downloads.html
-
- Also, get the latest version of this screen saver at my website...
- http://www.public.iastate.edu/~jaybebe/screen_saver.html
-
- You can also purchase it on my web-site, the version you have now will come up
- with a please register message after several uses, and it has some limited
- features until it is registered, registration is only $10.
-
- Just a note: you will probably have very slow performance unless you have a
- good graphics card, if it goes too slow then make sure you have your latest
- graphics cards drivers, if it still goes slow, then I am sorry, but this
- screen saver was specifically designed for high-end systems.

- This screen saver will leverage the quality of your opengl drivers to the
- extreme. It is entirely NOT fill rate limited on most cards, so pump the
- resolution up to the highest you can. I have identical results on my machine
- (a PII450 w/ Voodoo3) at 640x480x16 and 1600x1200x16, around 22-27fps using
- Preset 1. This is because the frame rate is heavily dependant upon polygon
- processing and throughput rather than fill rate and texturing.
-
- So if you want to dramatically increase or decrease FPS, then just tweak the
- X Y numbers, these are the divisions each axis is split into polygons, so if
- you have a xy of 50 35, then you will be sending 50x35x2 = 3500 triangles to
- be rendered, as you might know changing these numbers results in end effects
- of order x^2.
-
- Things that happen in real time:
- * calculation of normals (gouraud shaded)
- * summed intensities of each active wave with the sin function (up to 10 waves!)
- * summed normalized color components of each wave at each grid point
- * real time texture coordinate generation in environment map mode (chromify on)
-
- If you are not sure what video card or opengl driver you are currently using
- try using the OpenGL Switcher program, it allows you to switch OpenGL drivers
- back and forth quite easily. http://home.earthlink.net/~heavensrage/ogls.html
-
- Some people have reported poor performance using these savers with the Riva
- TNT. If this happens to you, check to make sure you are running in 16 bit
- color instead of 24 bit color. That has fixed the problem for most of them.
-
- 3dfx users please see the section below.
-
- This screen saver has been tested on:
- 3dfx Voodoo3, Voodoo2, Banshee, S3 VirgeDX, Riva TNT
- If you have a card other then this and it does or doesn't work, please email
- me and tell me so I can update this list.

-
- YOU MUST USE 16 BIT COLOR DEPTH IN ORDER FOR 3DFX TO WORK!
-
- I have tested it and it works with the Voodoo3 2000 and above, you must
- install the Quake3 compatable drivers. I did not rename or change any OpenGL
- dll's, after installing the new Q3 drivers it worked fine in any resolution at
- 16bit color depth. You can do this by just going into the screen saver
- confuration and selecting change resolution button, then select any resolution
- at 16 bit color depth and it should work awesome.
-
- You must have your resolution set at 640x480x16 or 800x600x16 for
- hardware acceleration to work on Banshee/Voodoo2 and older cards.
-
- Due to 3dfx's poorly written OpenGL driver, this screen saver does not work on
- all 3dfx cards. You can try using Mesa, which is a Glide emulated OpenGL
- driver which might work for you, goto www.mesa3d.org, or to directly download
- them, goto http://www.geocities.com/SiliconValley/Lakes/7220/mesa3dll.zip
-
- Don' get me wrong, I have a Voodoo3 and love 3dfx, its just that their opengl
- drivers SUCK! But, they should get them done sooner or later ;)
