Creating a grid

Sylves comes with a large array of built in grids, but sometimes you need something more custom. This page describes the various ways to get even more range from your grids.

Use MeshGrid

MeshGrid creates a grid which has one cell for every face in an input Mesh. Meshes are accepted in Unity's standard format, and can be created from a wide array of software and tools.

This is by far the easiest way to create practically useful grids as the tooling is so plentiful.

There's also MeshPrsimGrid which creates multiple cells per face, using extrusion to arrange the cells into layers, and PeriodicPlanarMeshGrid which repeats a mesh at fixed intervals across an infinite 2d plane, and PlanarLazyMeshGrid which generates a different mesh at fixed intervals.

Use modifiers

If you just want to customize an existing grid, there are various modifiers you can apply that change an aspect of their behaviour.

• BijectModifier - changes the cell co-ordinate system
• RavelModifier - changes the cell co-ordinate system to lie along the x-axis
• MaskModifier - restricts the grid to certain cells, similar to bounds
• TransformModifier - applies a linear transformation to the physical space of the cells
• PlanarPrismModifier - converts a flat 2d grid into a 3d grid by making multiple layers
• WrapModifier - causes a grid to wrap at the edges

Write your own grid

IGrid is of course an interface, and ultimately you can create your own implementations. Many of the more complex methods can be forwarded to methods in DefaultGridImpl which provides basic implementations.
