// This is a palette color shader for Unity game engine. It supports color cycling/palette shifting.
//
// The "index" is a greyscale image where each value is used to look up a color in the "palette" image.
// The palette can be any horizontal gradient.
//
// Blurring indices can look up the wrong color in the palette. So use an index with sharp pixels and no anti-aliasing.
// For mipmaps, generate mipmaps using nearest neighbor filter. Which can be done using GIMP by exporting as a .dds file.
// Or turn off mipmaps in the texture settings, or in this shader using the "filter mode."
//
// This shader is from this post: https://x.com/Vavassor/status/2109723733430517917

// Billboards are a flat image or sprite that always face the camera. This shader creates a billboard for each point
// in a point cloud. (a mesh using MeshTopology.Points)
// 
// This shader is for Unity's built in render pipeline.

// This is a lit shader example that doesn't use surface shaders.
// It supports forward rendering in the Built-in render pipeline. (BiRP)
//
// Annoyingly, it's not possible to support baked emission without a custom inspector,
// because there's no other way to set globalIlluminationFlags. So if baked emissions are required,
// switch the inspector to debug mode and change the flags manually.

About Blend Modes
https://docs.unity3d.com/6000.0/Documentation/Manual/SL-Blend.html

The following modes are used for combining the output of a shader to the framebuffer. (the screen, basically) If you wish to blend colors within a shader, instead see this article "Photoshop Blend Modes in HLSL" by Ryan Juckett. https://www.ryanjuckett.com/photoshop-blend-modes-in-hlsl/

    /*
    Transforms represent a position, orientation (rotation), and scale of an object. They also
    represent a translation, rotation, and dilation relative to position (0, 0, 0),
    rotation (0, 0, 0, 1), and scale (1, 1, 1).

    When a transform is applied to another, it is translated, rotated, and dilated. It combines transformations.

// Billboards are a flat image or sprite that always face the camera.
// 
// For a single billboard, put the material on Unity's Quad mesh. You may want to try enabling GPU instancing on the
// material, because this shader disables batching! Billboarding uses the object pivot, but batching combines meshes
// so they all have one pivot.
// 
// To use multiple billboards in one mesh choose Vertex as the Pivot Mode. For this you need a mesh that is a bunch of
// separate quads, each scaled down to a point. In Unity mesh import settings, make sure "Weld Vertices" is
// unchecked so they don't get welded together. Then this shader can display the billboards.
