3D Stylization

Project Overview:

In this project, I implemented two different stylizations using Unity ShaderGraph.

Results

• The initial reference was originally implemented in Unreal Engine. I incorporated certain features of it into my Unity shader.
  • I generated a brush stroke texture in Adobe Substance 3D Designer (DS) for the shader to sample, resulting in the creation of stroke-like features.
  • I utilized the dot product between the view direction and the object's normal to calculate the Fresnel term and then sampled the texture to produce eroded outlines based on that.
• The second stylization essentially combines Toon mapping with an outline effect.
  • I introduced some noise to the UV coordinates I sampled for creating the outlines, giving them a wavy appearance. To ensure the outlines change only at discrete time steps, I employed a floor function.
