Irrlicht Engine

I modified the demo code:

#include <irrlicht.h>
#include <iostream>
#include <windows.h>

using namespace irr;

#pragma comment(lib, "Irrlicht.lib")


class CSampleSceneNode : public scene::ISceneNode
{
core::aabbox3d<f32> Box;
video::S3DVertex2TCoords Vertices[4];
video::SMaterial Material ...

I think that I should write a class for texture splattiong without pixel shader for easy to use and can add any number of texture to be blended. Of cource, this solution is slower than pixel shader one.

I curiously want to know BlindSide's solution.

You mean texture splatting:

Here's my solution without pixl shader.(But slower.)

And Here's some reference:

Could we get some screenshots, please?


The Screenshot is here:

And can download code:

and modified engine code here:

Here is the D3D8 implementation:
1.Add the CD3D8MaterialRenderer_SPLATTING class in CD3D8MaterialRenderer.h file:


//=====================================locosoftware added=================================================

//! For texture splatting without pixelshader
class CD3D8MaterialRenderer ...

And to use it:

#include <irrlicht.h>
#include <iostream>
#include <windows.h>

using namespace irr;

#pragma comment(lib, "Irrlicht.lib")


class CSampleSceneNode : public scene::ISceneNode
{
core::aabbox3d<f32> Box;
video::S3DVertex2TCoords Vertices[4];
video::SMaterial Material;

public ...

First I got an idea with http://downloads.gamedev.net/features/hardcore/splatting/TextureSplattingDemo.zip in Direct3D 9.

I found same article:

And I'll try it.

May you share your solution with Irrlicht engine?

The effect is still unsuccessful.

I'm working on something very similar:

http://irrlichtirc.g0dsoft.com/BlindSide/terrainPaint1.JPG

It can blend up to 32 different kinds of textures on a terrain's surface.

Yes! This effect is exactly I want. But I didn't figure out how to implement it.
May you share your solution with ...

the problem has been solved....

There's a good example in http://www.gameprojects.com/project/?id=8fc946fc5f with XNA Framework 2.0. But it's only support four texture blending. I want to make a terrain editor and can paint many textures on the terrain with irrlicht.

I want to known how to blend different textures on each material's edge. There's many source code on Internet. But they are three or four texture types blend by pixel shader. I mean how can I blend any number of textures on each texture's edge.
The effect like this:

I want to transform world vertex to screen coordinates by my code. and with each transformed 2d screen point,draw a white rectangle. Here is my code:
(first I added renderPoint() and Modified render() from the CCubeSceneNode class )

CLocoCubeNode.h

#ifndef __LOCO_CUBE_NODE__
#define __LOCO_CUBE ...
