The Triangles field of the MeshPrimitiveType enum represents a primitive type used in rendering meshes. When using this type, the mesh is composed of individual triangles, each defined by three vertices. This is one of the most common and versatile primitive types for 3D rendering, allowing for complex shapes and surfaces to be constructed efficiently.
Use MeshPrimitiveType.Triangles when you need to render a mesh using triangles. This is suitable for most 3D models, as triangles are the simplest polygon that can define a surface in 3D space. When setting up a mesh, specify this primitive type to ensure the mesh is interpreted correctly by the rendering engine.
// Example of using MeshPrimitiveType.Triangles
Mesh mesh = new Mesh();
mesh.PrimitiveType = MeshPrimitiveType.Triangles;
// Define vertices and indices for a simple triangle
mesh.SetVertices(new Vector3[] {
new Vector3(0, 0, 0),
new Vector3(1, 0, 0),
new Vector3(0, 1, 0)
});
mesh.SetIndices(new int[] { 0, 1, 2 });
// Add the mesh to a scene or a game object
GameObject gameObject = new GameObject();
gameObject.AddComponent<MeshRenderer>().Mesh = mesh;
