This mod is intended to bring more depth to your textures by making shadows cast better around them.

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

Doom 3, Quake IV & Prey Relief Extreme Shaders v1.2 - Now updated by Dafama2k7.

Relief Mapping mod by Fabio Policarpo.

Brilliant Highlights up to v0.6b by Maha-X.

Extreme Quality mod & shaders up to v1.01 by Rygel.


	- Re-enhanced glprogs/interaction.vfp Relief mapping shader with BH NG latest tech. to increase specular & normal bumpmapping, more relieve, brilliant, metallic and smooth look alike !
	- Support for both Relief mapping textures & models for D3 base.
	- Support for both Relief mapping textures & models for D3XP ROE.


At the moment this mod only supports NVidia gfx cards or latest ATI gfx cards that are able to supports OpenGL32 v3.0 shaders, with at least DirectX v9.0c hardware support, but there will be a low-end version for old ATI gfx cards that only supports upto v2.0 shaders soon !


v1.2 - Just i noticed that the Relief author didn't convertit the models, only the textures to Relief mapping technique, i have done this, and now there is Relief not only for the textures used in the maps, but also for the models. In addition to this, i was noticed that was no supports for neither textures, not models for D3XP (ROE) and i also have converted all the textures & models now to Relief mapping, so now this mod supports both D3 base & ROE in one go, there's no need to do a separate mod.

Also i have re-enhanced the glprogs/interaction.vfp Relief shader with some new technique that i learned recently. :)

v1.1 - In this releasse the Relief Mapping technique has been mixed with the latest version of BH NG and also i have used some small techniques from the UEQ and Extreme Quality mods to enhance even more this shaders !

The results are amazing !!!


Always make sure there is disabled compresion for textures on D3, this is already done in the Doomconfig.cfg, but if someone wants to use his own Doomconfig.cfg make sure to have this lines on it to be able to see the Relief...

image_usePreCompressedTextures "0"
image_useCompression "0"

If you typed this from the in-game console you need to type vid_Restart now to activate.


Original Doc...:

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

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"


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!
