# Previews: [

](https://imgur.com/a/MXB2S) * From Left to Right : * Direction Offset * Streamer Color * Fade * Outline(Normal) * Direction Offset + Streamer Color * ZTest * Mask Texture Clip + Direction Offset * Dissolve * Refraction Invisible * World Position * Ramp (implemented with surface shader) * Normal in world space * Noise * Mosaic * Rim

* From Left to Right : * Diffuse in vertex level * Diffuse in pixel level * Half Lambert * Specular in vertex level * Specular in pixel level * Blinn-Phong

* From Left to Right : * Single Texture (Texture + Bling-Phong) * Normal in tangent space * Normal in world space * Ramp (implemented with vertex fragment shader)

* Above picture is the main texture, From Left to Right : * Alpha Blend + Double Pass * Alpha Blend + ZTest * Alpha Blend * Alpha Test * Original Ring (Standard surface shader)

* Alpha Series Artifacts: (Alpha Blend + Double Pass is Recommended!) * From Left to Right : * Alpha Blend (Causing Z-Fighting) * Left: Alpha Blend + ZTest (Wrong), Right: Alpha Blend + Double Pass (Correct)

* Basic Lightning vertex fragment Shader (implemented with Bling-Phong) * For A ~ E point lights: their intensities are 5.0, 4.0, 3.0, 1.0, 2.0 * Since Unity only consider at most 4 lights, the light D are not considered

* Basic Lightning & Cast/Recieve Shadow vertex fragment Shader (implemented with Bling-Phong) * A is point light with white color * B is directional light colored white, angle marked as white vector in the picture * The angle of B is (50.587, -32.592, 31.197) * Note that there is another wall in Scene Geometry clipped by the camera.

* Basic Lightning & Cast/Recieve Shadow Shader With Alpha Test (implemented with Bling-Phong) * implemented by configure Fallback as "Transparent/Cutout/VertexLit" * Light info: Directional Light colored white with angle (82.413, 15.049, 251.738)

* 2D Sprite Animation

* Fresnel & Reflect & Refract & Glass Effect * Glass Effect implemented by Conbine bump, refract, reflect, uv shift

* Comparsion to Reflect & Frensel

* Trying to make refelct more realistic * Trying Combining Lambertian with Reflect * I use Diffuse * Lerp(Diffuse + specular, ReflColor) to approach, however there might be a better solution * Shadow artifacts due to bias (Unity can only increase bias to 2!)

* 2D Image Sequence, Scrolling background water sprite and billboard

* Some Post Processing Effects * (Shown in gif) Brightness, Luminance, Contrast, Gaussian Blur, Bloom, Sobel edge detection * (Not Shown in gif) Motion Blur (Use Depth map or not), alternate edge detection using depth map, fog

* Hatching Effect & Toon Shading * Hatching is simple version of [Matthew Webb, Emil Praun,Adam Finkelstein and Hugues Hoppe, Fine Tone Control in Hardware Hatching, SIGGRAPH, 2001] * Toon Shading is simpling outline + ramp

* Dissolve + Bloom + Brightness & Contrast

* Water Effect using noise with refraction

* Screen space fog using noise & depth map

* Shield Effects

* Stockingize Effect to create Stocking

* Screen Space Wave Propagation Effect

* Lotion Effects (See original size screenshot for checking it's effect)

* Wave Effect with collision and reflect surface
