阿祥的開發日常 - Stipple Transparency Shader (Screen-Door Transparency Shader)

Unity Stipple Transparency Shader

Previews:

• 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
