Are you looking to give your Doom III gaming experience a little something extra? How a game looks is always important, and having the graphics tweaked can only accomplish great things! ...And this is why Dafama2K7 has made a return to D3Files with another updated graphics tweaking mod! The Relief Mapping technique has been mixed with the latest version of BH NG v1.1, and Dafama2K7 has also used some of the techniques from the UEQ and Extreme Quality mods to enhance this shader even more!

Relief Extreme Shaders will extract some textures from the game data pack and modify them to include depth information. All original files are mantained and you can quickly get back to your original Doom3 installation by deleting the extracted files.

Refer to the readme for more information.

Doom3 Relief Mapping
=====================


This modifcation will not damage your Doom3 installation. It will just extract some textures from the game data pack and modify them to include depth information. All original files are mantained and you can quickly get back to your original Doom3 installation by deleting the extracted files.

The modified Doom3 shader was created to test relief mapping technique with high-quality game art. Note, however, that some geometry will not look correct with relief mapping as the art for the game was not created for this effect. For correct use of the technique the edges of scene polygons should have no displacement (depth=0). But since the depth maps were created from the game normal maps this is not garranteeded.


For details about how relief mapping works refer to:

demo  -> http://fabio.policarpo.nom.br/files/reliefmap3.zip
paper -> http://www.shadertech.com/contest/#reliefmapping
         http://fabio.policarpo.nom.br/docs/ReliefMapping_I3D2005.pdf


To install this modification:

- from your Doom3 instalation path create folder doom3\base\glprogs\

- copy file interaction.vfp to folder Doom3\base\glprogs\

- drag and drop file doom3\base\pak004.pk4 into the tool normal2depth.exe

- wait for processing of all normal maps (this will create folder doom3\base\textures)

Include this in your Autoexec.cfg (already present in the mod)...:

seta r_testARBProgram "0"			// def. 0
seta image_usePrecompressedTextures "0"
seta image_useCompression "0"

vid_Restart

If you installed in the base the glprogs and textures folders, to remove the modification and get back to original Doom3 installation:

- delete the folder doom3\base\glprogs
- delete the folder doom3\base\textures

You must select ULTRA QUALITY mode in order to have the calculated depth maps loaded (or else you will see no relief at all).

Relief mapping is slower than standard normal mapping. For this reason, we recommend going down to 640x480 or 800x600 in order to get better FPS through the game. Works great with a GeForce7800 card!


Enjoy,
Fabio Policapo (fabio.policarpo@gmail.com) and Manuel M. Oliveira (oliveira@inf.ufrgs.br)
