Monster Design ---- Siloo

still in progress
This creature suppose to be the concept small boss of our pitch game, but I guess no one is going to use this.
I still want to finish it. It has no teeth right now, ha ha!

Universal Play Project started!

It's a student pitched game.

The game is about creating stories between two players who are going to use basic shapes to form 

the world of stories. However, they are going to communicate with each other without texts and words. 

Here are some concept of story stages that I made in 3DS MAX

Summer Project - Free Philly Mascot -- Kneehi

Knee-Hi is the mascot in the project Free Philly

I'm the 3d/2d artist and game designer in this project.

The project is about to build an application in Surface Table for intros of Philly neighbors.

Knee-Hi, the dog will lead players to walk through 8 neighbors and play four types of small games. 

The fur part of Knee-Hi is the interesting part.  

In fact, those furs are geometries.

However, I have to move on.

this is another practice from zbrush to low poly model 

this is the start from ZSphere

Toon Character Design - Bachi NO. 1

Still in working
Finally, normal mapping and texture mapping render in Maya real-time

I re-topology the head mesh in ZBrush and export the low poly model into Maya to add teeth hair and eyeball

Render in Maya with AO

Zbrush Model

Bachi is a skinning, optimistic and brave boy.

ZBrush Cartoon Character Creation

Inspiration is from Gromit and Knee-hi from Free Philly

However, my client wants hairy dog, which is hard to make from 3D into 2D, sign......

ZBrush Normal Map making

Actually it was started from zshpere, but I adjust meshes in 3DSMAX.

It's a simple practice, and I did some mistakes while dividing meshes

So, I re-unwrap the UV after carving.

 Carved enough for normal map 

Using normal map tool in ZBrush to export Normal Map

Note: when it was exported, Y axis would be flipped

test the normal map in Unity

Concept Art for Game Design Class

It's a concept art for a ruin city to fit our pitch project in our game design class.
The art combine two real photos and hand drawing to finish.

The little girl is the one character in the pitched game. I use a photo as a reference to re-draw it.
I intend to create a cute little girl to earn sympathy from players.

First sample of Windows Mobile Phone 7

For the project rendering test, I have to test the newest XNA 4.0
which just has been released on March 15th 2010.
Let's see

In fact, XNA 4.0 is very easy to use.
However there are several different things from XNA 3.1.
For my situation, there is no more Renderstate class. So if you want to change
any renderstate in the phone, you have to create separate state instance to change that.
like:


DepthStencilState dp = new DepthStencilState();
dp.DepthBufferEnable = true;
dp.DepthBufferWriteEnable = true;
effect.GraphicsDevice.DepthStencilState = dp;

another important thing is: phone is not allowed custom shader
In this rendering testing, I used AlphaTestEffect (drawing city), and Basiceffect (drawing City)
Basically, for a phone, it is very easy to implement 3D environment.

Velvet shader implemented in XNA

Basically,
cause I'm doing a project about XBOX avatar,
I try to use the shader that MS used in avatars.
I guess that shader is based on velvet.
So, I mixed the velvet, distant lighting and skinned model shader together to animate my looney dog in XNA.

The pity is my velvet shader is based on vertex shading
I'll try to do in pixel shading next time.

NPR shading implementation (color distortion + cel shading)

NPR shading   
Tool: ATI Rendermonkey
Language: HLSL
Concept:  
These technique takes me 5 passes to finish it. And some passes need to be improved.
Pass 0: Cel shading
Pass 1: Color distortion
Pass 2: Normal
Pass 3: image based ink shading
Pass 4: Combination (Final)
As you can see, the technique includes three common shading, Cel, Color Distortion, and normal based ink.
The feature is the color distortion:

The idea of this shading is simple:

first the color has to be changed from RGB to HSV.

Then, sample one pixels from two special texture, and compare their value.

If their differential is bigger than X, the S and V of HSV value of the mapping pixel on rendertagart should be the average of the two sampling pixels.

However, my way to transform the color space has some problems

these step still needs to be improved

Tone Shader

Tone Shading:

Tool: ATI Rendermonkey

Language: HLSL

Concept:  

Basically, this technique can be done by two pass. First, I create a basic infinite light shading to render to texture. The rendertarget uses the alpha to store the shading result. In the final pass, I use a 2D texture which is my "tone" map to lerp the last pass result. Done! 

Key Code:

pass0:

float4 ps_main(float3 pos : TEXCOORD1, float3 nrm : TEXCOORD2) : COLOR

{

    float  diffuse = min(1.0,max(0,dot(-Light_Direction,nrm)));

    diffuse = pow(diffuse,5);

    diffuse = (diffuse*4)/3.0; 

    float4 Col = float4(1,1,1,diffuse);

    return Col;

}

Pass1:

float4 ps_main(float2 tex: TEXCOORD0) : COLOR0

{   

   float4 color;

   float4 base = tex2D(Texture0,tex);

   float4 hatch = tex2D(Texture1, tex);

   color = lerp(hatch , base, base.a) ;

   return color * base; 

}
