Hi Cpl.Bator,

Amazing, cool and exactly what i need. Here is a little Example made with my MP 3D Engine and a created normal map from your program.

MP_normal_test.exe:

Code:

Code: Select all

MP_EntityBumpmapTexture (earth1,textur2)

MP_EntityTexture (earth2,textur)

MP_PositionEntity (Earth1,1,0,0) ; Position Earth1 
MP_PositionEntity (Earth2,-1,0,0) ; Position Earth2 

While Not MP_KeyDown(#PB_Key_Escape) And Not MP_WindowEvent() = #PB_Event_CloseWindow; Esc or close

    MP_TurnEntity (earth1,-0.05,0,0) ; Move Earth1
    MP_TurnEntity (earth2,-0.05,0,0) ; Move Earth2
    MP_RenderWorld () ; Hier gehts los
    MP_Flip () ;

it's 100% pb your engine ? why do you not use Opengl ? :D

Yes all commands are Purebasic codes and you can use a Purebasic lib file, you don't need a Dll (only DX9).

xperience2003 is working on a Opengl 3D System and this works great. I hope he will do sometimes a linux version. Long years ago i use BlitzBasic on amiga and then BlitzBasic 3D on PC. I want to have the same easy commands for 3D on Purebasic and find some good codes for DX9.

OpenGl Tlib (windows)

You have seen the picture 3DEarthDemo.png? :P

Hi Cpl.Bator,

in this case i send you a file to test your own Normal maps with 4 mesh types. you can load the texture and normal map and test it with sphere, cube, teapot (you know for all games the importants meshs like in the film "The bloody killer teapot coming on earth") and plane:

MP_normal_test2.exe

This code with the mp_engine looks like:

Code: Select all

hi , For more effect , you can add light and move this for play with the bump :)

And for TLib , it's doesn't work with pb 4.3 , "pb_string missing" , and Avast found virus in the archive :?

Hi Cpl.Bator,

the author works on a new version for 4.30, but he has only one example for now. Please use the SmalTLib instead the Tlib library.

http://www.digitalarts-egypt.com/tlx/tlibpublic.rar

I think the new version will come soon...

P.S. The TLib-terrain.pb, DemoFX-Bitmapfonts.pb, 3-TLib-Drawing3d.pb and 2-TLib-Drawing2d.pb example of the old Tlib works fine too

''By the way: Wouldn't be Parallax Mapping enough for that? It just makes a relief in one direction (normal map is grayscale), not like bump mapping using red, green and blue colorchannel.''

Not sure what you mean.

Bump mapping uses greyscale images.
Normal mapping uses RGB images.
Parallax mapping uses RGB normal map plus separate height map.

Parallax mapping can produce some incredible results, but these normal maps look good, a lot of bump to normal generators are a real pain to use.

Parallax Mapping

Oh, alright. I just read in Wikipedia (once upon a time :wink: ) that Parallax Mapping just uses a grayscale Map.
