Irrlicht Engine

What do you think about next generation game?
The Irrlicht is a good engine bat look as HL1! The next generation game have expense usage of shader and other effect as Bloom and HDR that require special feature. For example the Bloom effect require to store a separate Texture with light emettivity ...

I work around dynamic clouds! Bat before I write a Noise Generetor!
So i made a simple demo!

It is very very simple!

The binary demo is http://xeus32.altervista.org/index.php?mod=Download&file=demo/NoiseDemo.rar&mode=go

I want to save the render to texture image or load each pixel value
Is It possible? how ?

i have the same problem , so that i have changed SL to CG.

here is your shader program but with CG works fin with me.
void Vmain( float4 position : POSITION,
out float4 oPosition : POSITION,
out float2 oTexCoord : TEXCOORD)
{
float2 P = sign( position.xy );
oPosition = float4 ...

In my project i wont use high quality effect over opengl via GLSL.
If you wont to see my code i share the file project:

I have write a post process in irrlicht opengl. There is a big limit!
With glCopyTexSubImage call we can save image only power of 2. I have test to render a immage 1024 x1024 and i swap in zbuffer on a geForce 6600GT!
The function will be replace with "Render Directly to Texture" (WGL_ARB_extensions ...

Oh, you could eliminate cMyShaderCallBack and just make CBaseFilter inherit from IShaderConstantSetCallback and implement the appropriate methods. Then you don't need to allocate the callback object on the heap, you just pass a pointer to the base filter [this] when creating the shader material ...

Where is wrong?
there's my code :oops:


// Class automatically generated by Dev-C++ New Class wizard

#ifndef CSHADERCALLBACK_H

I use glsl for post processing. Now i use only a black and white filtring.
I develop the shader with render monkey all work fine. When i use in irrlicht the shader faild to compile! Why?

to load shader and post process class i use this :

I want to understend why in the irrlicht exemple we use a heightmap 256x 256 that is not properly supported!!!!

This is my code for load the obj

// Load from file and fill structure
void cObjAvable::LoadXML(void )
{

io::IXMLReader* Reader =device->getFileSystem()->createXMLReader("config.xml");
if (Reader==NULL)
{
IFileSystem * fs = device->getFileSystem();
printf("Errore Glocabal\nimpossibile ...

>Your heightmap should be 257x257. The heightmaps used with the terrain node >should be square and in the dimensions of 2^N+1 ( i.e. 17x17, 33x33, 65x65, >129x129, 257x257, 513x513, etc. )

Why the image in terrain example ( terrain-heighmap.bmp ) is 256 x 256 pixel?
If i use the size of 129, 257 i ...

The terrain scene node not support rectangular map!

The error is here

TerrainData.Size = heightMap->getDimension().Width;
.
.
.

for (int x=0; x<TerrainData.Size; ++x)
for (int z=0; z< TerrainData.Size; ++z)

it is indispensable change the definiscion of Size to be able use 2 different index ...

Why if I use a Map 256 x 256 size with scale value (40,4,40) i obtain a map 9560 x 9560 ????
And why The terrain is always squared also i use rectangular map?

I write my class event receiver in MyEventReceiver.h :

/*
* MyEventReceiver
*/
class MyEventReceiver : public IEventReceiver
{
public:
virtual bool OnEvent(SEvent event);
SEvent MyEvent;
// Eventi Gui
bool MyGuiEvent();
// Key Imput
bool MyKeyInput();
private:
