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 shows a simple 3D pyramid whose apex moves upward or downward when the user presses the arrow keys. It demonstrates how to create and update a mesh at runtime using Unity’s Mesh API, with vertex data stored in a `NativeArray<float3>` for efficient modification. The code sets up a triangle-based submesh, defines vertex and index buffers via `SetVertexBufferParams` and `SetIndexBufferParams`, and redraws the mesh each frame with `Graphics.DrawMesh`. The pyramid is rendered using a provided material, and only the top vertex’s position is altered in response to input.

This example showcases a collection of procedurally generated grid-based polyhedral meshes, including hex, square, triangle, rhombille, Cairo, and Penrose tilings, each rendered as a 3D Unity mesh. It demonstrates how the Sylves library constructs and bounds different grid types, converting them into PolyMesh data via `grid.BoundBy(bound).ToMeshData()` and processing the resulting indices based on topology (triangles, quads, or NGons). The code uses Unity’s `MeshFilter` and `MeshRenderer` components, along with the Polyhydra Core library, to visualize each grid’s cell layout at a user-defined size.

This example shows how to convert a 3D mesh into a point cloud by changing its topology. It displays the original geometry as a set of discrete vertices instead of connected triangles. The code uses Unity’s `MeshFilter` and `Mesh` APIs, setting the mesh’s indices to cover every vertex and applying `MeshTopology.Points` to render each vertex as an individual point. It operates both in edit mode and during play, updating the shared mesh or the active mesh accordingly, making the conversion immediate and visible in the scene.

This visualization renders uniform polyhedra using a kaleidoscopic construction method. The code computes vertex coordinates, faces, and symmetry groups from fundamental angles, then draws the three-dimensional shapes with projected lines and filled polygons. It uses standard C math and graphics routines for coordinate transformation and rendering, including trigonometric functions for rotation and perspective. The display cycles through different polyhedral types, showing their geometric structure through edge networks and face shading.

This example demonstrates a mesh-subdivision algorithm that transforms a Conway polyhedron by offsetting its vertices and adding new faces at edge midpoints. It shows how the original geometry is refined into a smoother, more complex structure while preserving the polyhedron’s topological connectivity. The code uses custom `ConwayPoly`, `Face`, `Halfedge`, and `Vector3` classes, along with LINQ operations like `Select` and `Find`, to manipulate vertex positions and face indices. The rendering approach relies on the polyhedron’s internal data structures, with the offset parameter controlling the inflation of each vertex along its normal.

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 example shows a Unity-based 3D modeling interface where users subdivide a cube or quad primitive into finer meshes. A grid of buttons lets the user choose different subdivision resolutions (from 2x2 up to 6x5), with the current state highlighted. Selecting a subdivision switches the mesh and opens a vertex-mover dialog for fine-grained editing, while an intermediate confirmation step is shown if vertex changes already exist. The included JSON conversion functions demonstrate how changed vertex positions and smoothing angles are serialized and restored, including reference-based deduplication of shared vertex patterns.

This example renders a 3D mesh of a Brazier-shaped polyhedron, built from a JSON specification and processed through a sequence of geometric operations. The shape starts as a uniform hex grid prism, then applies operations such as `FaceScale`, `Extrude`, and `Kis` to selected upward-facing faces, producing a sculpted, bowl-like form with a faceted interior. The model uses a hex grid type with prism parameters and a "Dirty Metal" appearance preset, suggesting a material-based shading pipeline. The visualization relies on the JSON’s operation list to transform the base geometry, with disabled operations like `Lace` indicating optional refinement steps that remain inactive in the final output.
