X3DOM - Day 1

X3DOM

%-------------------------------------------------------------------------------

Goal : Multi-channel visualization based on the X3DOM

Todo :

1. Study

• How to apply shader for edge blending and warping?
• How to manipulate camera projection matrix on X3DOM?
• How to synchronize variables using js?

    2. Design

• Web-based system
• What will be the main difference with multi-channel visualization using Unity3D?
• Connect-and-play?

    3. Implementation

• TBA...

%-------------------------------------------------------------------------------

• How to apply shader for edge blending and warping?

- X3DOM supports GLSL,HLSL,Cg shader language

- <ComposedShader> and <ShaderPart>node is used until now

- Shader code can be separated with x3d body, which will be tested later

- Toon Shading Test (done)

• Modify a little for my own from examples HERE

- Edge Blending Test (ongoing)

• Shader of existing edge blending(for Unity3D use) is converted in GLSL for test
• You can see the attenuation on the side parts.
• Warping also implemented, but the result shows something wrong with the UV coord. Should be checked later.
