bump mapping

is there any function out there, with which you can type "entitybumpmap (entity, "bumpmaptexture.bmp")" before the loop and "updatebumpmap()" in the main loop??? I've been on a hunt for a function of this sort, without any success. I hear tom's DLL can do this, but I cannot find it anywhere. Can anybody help??

I've uploaded all my DX7-Libs for B3D. I don't know which one is the right one, so you have to try yourself.

try the devil shadow system instead; its a full library. download it in my signature!

t3K|Mac, thanks a lot!

dss does ENBM, not quite what i'm looking for, t3K|Mac, i'm looking into your files now. (I need just plain old bump mapping, normal mapping, whatever you want to call it)

Ok, found it in "anotherDX7 too", but how do i use it?

;Bump Mapping
UserBumpTexture():"_UserBumpTexture@0"
EnableRenderBumpTexture():"_EnableRenderBumpTexture@0"
DisableRenderBumpTexture():"_DisableRenderBumpTexture@0"
SetBumpInfo(m00#,m10#,m01#,m11#,lumScale#,lumOffset#,bumpMode%):"_SetBumpInfo@28"

how do I use these?

I have a source, i think this is what you are looking for:

or download the archive with bumpmaps + dll:

http://www.t3k-entertainment.com/freefiles/bumpy_text_demo.zip

works beautifully, thanks

ditto, the bumpmapping affects the cubemap texture, is there a way to bumpmap the diffuse texture??

the DLL in the DSS is absolutely the latest there is!!!!!!

that's still ENBM, I want diffuse bump mapping, the simple stuff for non-shiny surfaces

that wont be possible with toms dll which you want to do it

then with what can it be done?

with the simple commands of b3d

I'm a total noob to texture-editing and stuff(with almost a year of experience), enlighten me on how :)

Tab, that code doens't take into consideration the position and movements of lights does it? As in the 'bump' on the object won't update if a light moves across it?

Normal maps don't react to DX light sources, you must do it manually and either color the vertices manually or use a different approach to map the normal light color onto the object

My code is only a little example.

This code take in consideration the position of the light.

I'll check that out tab, thanks
