Re: bump texture
Hi aiman ,
A bump texture is a monochome image which simulatess bumps on the top of a surface.
It uses shades of grey, white and black. White being the highest point, and black being the lowest point.
You can easily make these in photoshop or any other 2D art package.
However bump maps do not actually change the shape of geometry so from certain angles they can still look flat.
The bump map basically simulates the way light hits an object to create an illustion of a bump.
However for many years now games have been using normalmaps. These are special bump maps which are a purple colour, and these perform much better than bumpmaps.
These can be created by baking a high resolution model down to a low resolution model, or by creating a map using the nvidia plugin for photoshop.
Normalmaps work much better than bump maps because they catch the light in 3d space and actually do look like they are changing the shape of the geometry.
You also have displacement maps which actually change the shape of the model, but these are more processor intensive and should be avoided in games.

Thank you
but in irrlicht how can use bump texture ?

Re: bump texture
If you've created a model in a modelling package, just export it and import it into Irrlicht. If you want to to set it on a model already in Irrlicht, you can't, you need to convert it into a normal map. If your model is in the OBJ format, you can set a bump map in the MTL file.
