Water (and other fluids)

It's here, nerds. I added support for a whole ass fluid overlay system that drives some procedural water effects, then I applied it to water, lava, slime, and your mother. It basically replaces those surfaces with animating, quasi-fluid-sim-y, surfaces. They have illusory height, reflect things, and flow. I will probably iterate on this some more; I still want to come up with something for water/slime/lava-falls. This is a start though! Surprised I used a semi-colon in there? I got an 800 on the verbal on my SATs, and it shows.

I'm now actively pursuing AMD support. Once that's out of the way, I think there's some visual tuning to go, and then I'm going to consider Duke done! What comes next after that though...? I GUESS WE'LL SEE.

How to install/run (Windows):

1. Purchase and install Duke Nukem 3D: 20th Anniversary World Tour (or otherwise have it installed on your computer - you need a commercial version of Duke 3D to use with the Duke-RT engine fork)
2. Download the .zip file in the assets section from this release
3. Unzip Duke-RT to your computer
4. Run launch-duke-rt.cmd in that folder
5. Give it the path to your Duke 3D install (if it doesn't find it automatically)
6. Let it grab the normal maps from Duke World Tour (if that's your Duke version, will still work without them)
7. Let it open your browser to grab the voxels
8. Download the voxels from that site
9. Go back to the Duke-RT console window and hit enter
10. Let it unpack the voxels into its own directory for you
11. Proceed into the game
12. Always run via launch-duke-rt.cmd in the future

How to install/run (Linux):

1. Purchase and install Duke Nukem 3D: 20th Anniversary World Tour (or otherwise have it installed on your computer - you need a commercial version of Duke 3D to use with the Duke-RT engine fork)
2. Download the Linux tarball in the assets section from this release
3. Untar Duke-RT to your computer
4. Run launch-duke-rt.sh via CLI from that folder
5. Give it the path to your Duke 3D install (if it doesn't find it automatically)
6. Let it open your browser to grab the voxels
7. Download the voxels from that site
8. Go back to the Duke-RT console window and give it the path to your voxel zip file
9. Let it unpack the voxels into its own directory for you
10. Let it grab the normal maps from Duke World Tour (if that's your Duke version, will still work without them)
11. Proceed into the game
12. Always run via launch-duke-rt.sh in the future

What's coming next:

• AMD support
• Water and fluid tuning
• Another lighting pass on episodes 1 through 3
