Hi omaremad,
I've created a debug version of loader with bumpmaps, but it's a little bit difficult to use in the way you suggested, I've implemented a new way in which you must set bumpmaps instead of lightmaps from within DeleD, but since new DeleD 1.31 has been released today with some new features I'll add some new features to loader before bumpmaps (alphamaps now works in DeleD Pro).
For now I've adjusted some things (you can specify texture paths,and you can use DeleD's path dir if wanted).
Another thing is that if you use bumpmaps I could not use oct tree node for DeleD level it's just dmf mesh or is it for all mesh loaded as octree?
Bye
and I think that these features will be included in the next Irrlicht release, I'll send to Niko once tested new versions.

I've finished shader implementation and it's integration in DeleD Level Preview (I've not released version with flashlight shader cause I want to add some other things ), now it works really well look at this:
I've spent a lot to obtain real light effects on surfaces and I think I've reached a good level.
User will also set some things (I'm adding light color ):
and finally what do you think of a laser pointer based on this effect?
The bad new (not for me ) is that I've last decided to go to Malta on monday so it means I'll probabily won't release a new version before September (I'll continue to work until Sunday but I'm not so sure I'll end it 
).
Anyway I'll do my best to finish these features and then I'll pass to implement new trasparent materials in DMF loader.
Ah, someone asked me to have my shader code, I'll release soon as I'll release DeleD Level Preview new version (since your request I've changed my shader structure a thing like 20 times) anyway I'll put here my last code snapshot:
This is all for now....Bye All

@illbuzzo there is nothing that can stop u when u want to do some thing is there?
good work i really want this since it would make irrlicht comparable to the amp engine.

This tutorial shows how to use shaders for D3D8, D3D9 and OpenGL
with the engine and how to create new material types with them. It also
shows how to disable the generation of mipmaps at texture loading, and
how to use text scene nodes.
This tutorial does not explain how shaders work. I would recommend to read the D3D
or OpenGL documentation, to search a tutorial, or to read a book about this.
At first, we need to include all headers and do the stuff we always do, like
in nearly all other tutorials:

Because we want to use some interesting shaders in this tutorials, we
need to set some data for them to make them able to compute nice
colors. In this example, we'll use a simple vertex shader which will
calculate the color of the vertex based on the position of the camera.
For this, the shader needs the following data: The inverted world matrix
for transforming the normal, the clip matrix for transforming the position,
the camera position and the world position of the object for the calculation
of the angle of light, and the color of the light. To be able to tell the
shader all this data every frame, we have to derive a class from the
IShaderConstantSetCallBack interface and override its only method,
namely OnSetConstants(). This method will be called every time the material
is set.
The method setVertexShaderConstant() of the IMaterialRendererServices interface
is used to set the data the shader needs. If the user chose to use a High Level shader
language like HLSL instead of Assembler in this example, you have to set the
variable name as parameter instead of the register index.

opengl.ps and opengl.vs. We only need the right filenames now. This is done in the
following switch. Note, that it is not necessary to write the shaders into text
files, like in this example. You can even write the shaders directly as strings
into the cpp source file, and use later addShaderMaterial() instead of
addShaderMaterialFromFiles().

In addition, we check if the hardware and the selected renderer is capable
of executing the shaders we want. If not, we simply set the filename string
to 0. This is not necessary, but useful in this example: For example, if
the hardware is able to execute vertex shaders but not pixel shaders, we create
a new material which only uses the vertex shader, and no pixel shader.
Otherwise, if we would tell the engine to create this material and the engine
sees that the hardware wouldn't be able to fullfill the request completely,
it would not create any new material at all. So in this example you would see
at least the vertex shader in action, without the pixel shader.

Now lets create the new materials.
As you maybe know from previous examples, a material type in the Irrlicht engine
is set by simply changing the MaterialType value in the SMaterial struct. And this
value is just a simple 32 bit value, like video::EMT_SOLID. So we only need the
engine to create a new value for us which we can set there.
To do this, we get a pointer to the IGPUProgrammingServices and call
addShaderMaterialFromFiles(), which returns such a new 32 bit value. That's all.
The parameters to this method are the following:
First, the names of the files containing the code of the vertex and the pixel shader.
If you would use addShaderMaterial() instead, you would not need file names, then you
could write the code of the shader directly as string.
The following parameter is a pointer to the IShaderConstantSetCallBack class we wrote
at the beginning of this tutorial. If you don't want to set constants, set this to 0.
The last paramter tells the engine which material it should use as base material.
To demonstrate this, we create two materials with a different base material, one
with EMT_SOLID and one with EMT_TRANSPARENT_ADD_COLOR.

This tutorial shows how to use shaders for D3D8, D3D9 and OpenGL

shows how to disable the generation of mipmaps at texture loading, and
how to use text scene nodes.
This tutorial does not explain how shaders work. I would recommend to read the D3D

Because we want to use some interesting shaders in this tutorials, we
need to set some data for them to make them able to compute nice
colors. In this example, we'll use a simple vertex shader which will
calculate the color of the vertex based on the position of the camera.
For this, the shader needs the following data: The inverted world matrix
for transforming the normal, the clip matrix for transforming the position,
the camera position and the world position of the object for the calculation
of the angle of light, and the color of the light. To be able to tell the
shader all this data every frame, we have to derive a class from the
IShaderConstantSetCallBack interface and override its only method,
namely OnSetConstants(). This method will be called every time the material
is set.
The method setVertexShaderConstant() of the IMaterialRendererServices interface
is used to set the data the shader needs. If the user chose to use a High Level shader
language like HLSL instead of Assembler in this example, you have to set the
variable name as parameter instead of the register index.

it sucks that you would license 50 lines of code like that. anyone can just rewrite your code with and steal the idea without asking for permission anyway,
all that license does is prevents it from ever being included in irrlicht.
Hi All,
just to be clear :
Maybe you should read well licenses, cause this is just a temporary license untill I'll decide a standard license (to be included in Irrlicht it must be zlib, I usually use GPL), in the meanwhile you can use this shader for your projects just reporting the author and license or modifications. It's not a problem of Irrlicht or other libraries, It's just what you want to do with it, if you want to use in a commercial product just contact me and I'll say if you can or can't use and what the conditions are.
I changed DMFLoader license (it was GPL) for inclusion in Irrlicht (it's an exception to main license) and so I'll do with this shader when ready.
If you not agree with this license do not use flashlight shader and write your own, it's simple, there are a lot of ways or wait for final release.
Bye all
just to be clear :
Code: Select all
*If you intend to use this code in other ways please contact*
*the author at info@ilbuzzo.net. *
*The author reserve himself the right to change this license*
*or create particular licensed versions. *

lol why dont you copy his code, change it a bit, remove all comments, rename some things and then use it yourself ? no one can tell that you didnt do it!
ok i wouldnt do it like this because i hate to copy&paste and i would have a bad concience but its a solution if you want to have it commercial...

yeah that was my point.. the letter of the law can't protect the code, you can legally have the shader in commercial wares for by rewriting it. the problem is that kind-hearted open source developers are stopped by the spirit, not the letter.
restricting snippets like this stops them from evolving, but it doesnt stop people from using without permission to make money. good suffers while evil prevails, so I had to comment.
