A Unity shader demonstrates a mesh-spherization effect by morphing a flat textured surface into a sphere. The vertex shader normalizes each vertex position, scales it by a configurable radius, and blends between the original and spherical coordinates using an amount parameter. The fragment shader samples the main texture and halves its color output. The shader uses Unity's `UnityObjectToClipPos` for projection and applies fog through standard CG macros. The material exposes radius and amount properties for interactive control.

This Unity shader example demonstrates a custom lighting model with diffuse reflection for both vertex and pixel lights. It shows how materials respond to multiple light sources, combining ambient, directional, and point/spot lighting using additive blending. The shader uses Unity's CGPROGRAM syntax, leveraging built-in variables like `unity_4LightPosX0` and `unity_LightColor` for vertex lighting, while `_WorldSpaceLightPos0` handles additional light attenuation. The code includes two passes: a ForwardBase pass for ambient and vertex lights, and a ForwardAdd pass for supplementary lights, with linear distance-based attenuation for point sources.

This example demonstrates a custom outline effect for the Unity Universal Render Pipeline (URP). It consists of a `ScriptableRendererFeature` that injects a depth-normals prepass, which renders the scene’s depth and normal information into a texture. A Shader Graph custom node exposes this `_CameraDepthNormalsTexture` as an input, and an HLSL function compares depth and normal values at neighboring screen-space texels to detect edges. The effect produces a stylized outline by thresholding depth discontinuities and normal differences, with adjustable scale, depth threshold, normal threshold, and texel size.

This example shows a Unity shader that applies triplanar texture mapping to surfaces, blending three planar projections based on each fragment’s local normal direction. The shader, written in HLSL with the Standard Surface shader model, samples a main texture, normal map, and occlusion map across the X, Y, and Z axes, then weights the results by the normalized absolute normal components. It supports transparency, metallic, glossiness, and occlusion parameters, and relies on Unity’s `surf` and `vert` functions. The code is adapted from keijiro’s StandardTriplanar shader and runs in the Unity engine.

This visualization renders a 3D raymarched scene using a single shader written in HLSL. It displays a collection of geometric primitives—planes, spheres, boxes, ellipsoids, tori, cylinders, cones, prisms, capsules, and pyramids—each defined by signed distance functions (SDFs) and composited in a shader. The code includes multiple SDF implementations with both distance-bound and correct-distance variants, demonstrating how shape intersections and subtractions are computed. The scene is rendered through a fragment shader that applies raymarching techniques, with an anti-aliasing toggle controlled by the `AA` constant.

a triplanar / procedural UV / world space UV shader for Unity, cobbled together bits from @QuickFingerz and @Farfarer

This shader demonstrates triplanar texturing, projecting three separate textures onto an object’s surface based on its world-space normal direction. It blends side, top, and bottom texture samples using a power-saturated normal projection, with side textures sampled from the X and Z axes and top/bottom textures from the Y axis. The Unity shader uses a surface shader with Lambert lighting, and it applies world position coordinates to compute UVs, scaling each texture independently. The result is seamless, stretch-free texturing for arbitrary geometry without relying on traditional UV mapping.

This visualization renders a raymarched shader scene in Unity, showing two intersecting spheres whose sizes and positions are modulated by a repeating sine wave. The code in `spheres.cginc` defines a distance function that combines a static sphere with a second sphere whose radius oscillates via `_SinTime`, using a smooth maximum operation to merge their shapes. The scene is generated entirely on the GPU through the shader, with no external data source, and the repeating pattern is created by applying a modulo operation to the position coordinates.

This visualization demonstrates Möbius transformations applied to a 3D object in real time. A shader written in Unity’s ShaderLab and CG/HLSL takes each vertex, performs a reverse stereographic projection onto a 3-sphere, rotates the hypersphere in 4D space, then projects back to flat 3D. The user controls the rotation amount via the `_Amount` slider. The surface shader uses the Standard lighting model and applies vertex colors, with adjustable saturation, smoothness, and metallic properties through exposed parameters.
