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.

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 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.

A custom Unity shader renders double-sided foliage with a spherical normal trick, replacing each vertex’s normal with a direction from the model origin to the vertex. It combines alpha-cutout transparency with Fresnel-based edge fading, using `clip` to discard pixels below a cutoff. The shader applies Lambert diffuse lighting from `_WorldSpaceLightPos0` plus ambient light via `ShadeSH9`, while normals are offset by a vector property. The material is intended for tree models, as noted in the author’s comments, and supports alpha testing in the `TransparentCutout` render queue.

This example displays a tetrahedron built from four triangular faces, with each face defined by three vertices and connected to form a closed 3D shape. The code uses Unity’s MeshFilter and MeshRenderer components, creating a new Mesh object and assigning vertex positions and triangle indices manually. It computes the geometry using vector math, including square roots for equilateral triangle proportions, then calls RecalculateNormals and RecalculateBounds to prepare the mesh for rendering. The script runs in edit mode via ExecuteInEditMode, so the tetrahedron appears immediately in the Unity editor without requiring playback.

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 shader example demonstrates a technique for snapping pixel-art sprites to a fixed pixel grid in a 3D game engine. It shows how vertex positions are aligned to integer multiples of a tunable “pixels per unit” value prior to rendering, preventing visual distortion or shimmering when sprites are placed in world space. The code is written for Unity’s proprietary shader language and uses a Cginc/UnityCG-style vertex and fragment program, aligning object-space vertices before passing them through the standard MVP matrix. The shader samples a main texture and optionally an external alpha texture, tinting the result with a `_Color` property.

This visualization shows a raymarched 3D scene where a box and a sphere blend together, with a small protective void around the object. The shape repeats in a mirrored grid pattern that scrolls over time, driven by the `_Time.x` uniform. The code defines signed distance functions in a Unity shader file (`weirdboxes.cginc`), using custom `fBox`, `fBoxCheap`, and `pModMirror2` functions to compute the scene geometry, with a guard term that adds a thin hollow shell around the result.
