struct · iOS 15.0+ · SDK 27.1

struct MeshDescriptor

Defines a 3D mesh's structure and data. Create or modify 3D shapes in a RealityKit scene using `MeshDescriptor`, which provides properties and methods to define the vertices, normals, texture coordinates, and other attributes of the mesh. Apply the mesh to an ``Entity`` by creating a ``MeshResource`` with ``MeshResource/generate(from:)-6l1q2``, and create a ``ModelComponent`` with ``ModelComponent/init(mesh:materials:)``. Start by creating a basic triangle with a `MeshDescriptor` instance. ```swift var descriptor = MeshDescriptor(name: "triangle") descriptor.positions = MeshBuffers.Positions([ [-1, -1, 0], [1, -1, 0], [0, 1, 0] ]) descriptor.primitives = .triangles([0, 1, 2]) ```
