Hex terrain editor [updated]

[elvman]

Finally I released my terrain/splatting editor. Here are some screenshots:


Features:
Terrain editing
Lightmap (with shadows) generation and filtering
Splatting
For now editor supports only 2 splatting overlays (because of limitations of Irrlicht).
Load save lightmap/splat map (heightmap saving does not work for now, but I will fix this) and save project into .xml file (later I will release the terrain scene node, which is able to load them).

Future plans:
Changing/editing brushes.
Changing the light direction
LOD
More splatting layers

Download: here
Development thread: here

Check it out and post your suggestions etc. here.

Will you be releasing it with source code?

[elvman]

Will you be releasing it with source code?

I will decide later if I will release the source of the editor, but I for sure will release the source of modified ShlTerrain scene node (you will be able to load Hex editor's output in your application with it). For now I just want to give Irrlicht developers a tool to generate good quality terrain for their game.

That looks really pretty! Well done!

Hey I modified the shaders so that it automatically produces rock texture on steep parts without doing any splatting. Here is an image showing this in action:



This is what the new shaders look like:

HLSL PS:

Code: Select all

sampler2D coverage; //coverage
sampler2D lightmap; //lightmap

sampler2D splat1;
sampler2D splat2;

// Pixel shader output structure
struct PS_OUTPUT
{
    float4 Color : COLOR0;  // Pixel color    
};

struct PS_INPUT
{
	float4 Position : POSITION;
	float4 Diffuse  : COLOR0;
	
	float2 LightmapTexCoord : TEXCOORD1; //lightmap texture coords
	
	float2 SplatTexCoord1 : TEXCOORD2; //1st spalt texture coords
	float2 SplatTexCoord2 : TEXCOORD3; //2nd spalt texture coords
	float normalDist : TEXCOORD0;
};
	
PS_OUTPUT main( PS_INPUT Input ) 
{ 
	PS_OUTPUT Output;

		
	float4 TexColor = lerp(tex2D( splat2, Input.SplatTexCoord2),
					tex2D( splat1, Input.SplatTexCoord1),Input.normalDist);
	
	float4 LightmapColor = tex2D( lightmap, Input.LightmapTexCoord );  // lightmap

	Output.Color = Input.Diffuse * TexColor * LightmapColor;

	return Output;
}

HLSL VS:

Code: Select all

float4x4 mWorldViewProj;  // World * View * Projection transformation

// Vertex shader output structure
struct VS_OUTPUT
{
	float4 Position   : POSITION;   // vertex position 
	float4 Diffuse    : COLOR0;     // vertex diffuse color
	
	float2 LightmapTexCoord : TEXCOORD1; //lightmap texture coords
	
	float2 SplatTexCoord1 : TEXCOORD2; //1st spalt texture coords
	float2 SplatTexCoord2 : TEXCOORD3; //2nd spalt texture coords
	float normalDist : TEXCOORD0;
};

struct VS_INPUT
{
	float4 Position	: POSITION;
	float3 Normal		: NORMAL;
	float4 Diffuse		: COLOR0;
	float2 TexCoord0	: TEXCOORD0;
	float2 TexCoord1	: TEXCOORD1;
};


VS_OUTPUT main(VS_INPUT Input)
{
	VS_OUTPUT Output;

	// transform position to clip space 
	Output.Position = mul(Input.Position, mWorldViewProj);
	
	Output.Diffuse = Input.Diffuse;
	Output.LightmapTexCoord = Input.TexCoord1;
	
	Output.SplatTexCoord1 = Input.TexCoord0;
	Output.SplatTexCoord2 = Input.TexCoord0;
	
	Output.normalDist = Input.Normal.y;
	
	return Output;
}

If it's over the capabilities of my card will you make an option for it to be turned off xD

[BlindSide]

It shouldn't be over the capabilites. IIRC it didn't allow more than 4 texcoords so its probably even lower than PS 1.4. It'll run fine on your card MonkeyCracks...

BTW The thing I just made goes faster then the original splatting thing because it doesn't have to read from an additional texture to know how to splat it, it just tests the normal.

[elvman]

I will leave it up to users' choice whether to use Shaders 1.1 (2 splatting layers) or Shaders 2.0 (6 splatting layers).

Hi. I've tested it. It's great! Like a 3D painter for landscape.

This should be great for creating "trails"!
This is excellent. I just can't wait to see the next release of this editor!

[elvman]

I just finished the realistic water scene node (I use it for landscapes) and now I am working on the splatting terrain. I will release the next (hopefully full) version of Hex terrain editor when these scene nodes will be finished.

[Virion]

Nice editor. Your terrain is very smooth. And the texture splat looks good too. Great.

[elvman]

Finally released the next version of Hex editor with load/save options enabled. The heightmap saving/loading still does not work, but I will fix this in the next release.
First post updated.

Hey no offense but "Hex Editor"? A Hex editor is a used for modifying code such as this one:

I came thinking someone had built a Hex Editor in Irrlicht code...

[TheGameMaker]

me 2^^ its looking cool though..

[elvman]

Hey no offense but "Hex Editor"? A Hex editor is a used for modifying code such as this one:

There were many reasons why we chose the name "Project Hex" for our project an that's the reason why project's built-in level editor is named "Hex editor". But I agree that it can be confusing and changed the topic's title to "Hex terrain editor".
P.S. The editor I am presenting here is not a fully functional level editor, it is only a terrain editor (the real level editor is a little bit upgraded and has all needed features for our game).
