bgolus / CameraFacingBoxRaycast.shader
Created July 6, 2020 00:07
A "single triangle" cube shader. Really a shader that orients a flat mesh towards the camera and uses a box ray intersection to draw a cube in the interior.
Shader "Unlit/CameraFacingBoxRaycast"
{
Properties
{
_Cube ("Texture", Cube) = "" {}
_MeshScale ("Mesh Scale", Float) = 1.0
[Toggle] _DisableCameraFacing ("Disable Camera Facing", Float) = 0.0
}

bgolus / MatCapTechniques.shader
Created January 29, 2022 00:37
Showing multiple matcap techniques, including a proposed improved method that's no more expensive than the usual fix if you're starting with the world position and world normal.

A modification of Kyle Halladay's Pencil Sketch Effect shader from his blog post here: http://kylehalladay.com/blog/tutorial/2017/02/21/Pencil-Sketch-Effect.html
// A modification of Kyle Halladay's Pencil Sketch Effect shader

// Blends between two scales of hatching based on distance and camera fov to
// keep a perceptually constant hatching scale (assuming consistent mesh UVs).
