]Mesh class
A mesh is made of many n-sided polygons.
public class Mesh : Geometry, IEnumerable<int[]>, IMeshConvertible
Constructors
| Name | Description |
|---|---|
| Mesh() | Initializes a new instance of the Mesh class. |
| Mesh(string) | Initializes a new instance of the Mesh class. |
| Mesh(TextureData) | Construct a mesh using specified height map, if the height map’s pixel format contains multiple components, the first(usually the red) component will be used as the height value(z) The control point’s x and y components are normalized pixel coordinate. |
| Mesh(TextureData, Matrix4) | Construct a mesh using specified height map, if the height map’s pixel format contains multiple components, the first(usually the red) component will be used as the height value(z) The control point’s x and y components are normalized pixel coordinate. |
| Mesh(TextureData, bool, Matrix4) | Construct a mesh using specified height map, if the height map’s pixel format contains multiple components, the first(usually the red) component will be used as the height value(z) The control point’s x and y components are normalized pixel coordinate. |
Properties
| Name | Description |
|---|---|
| CastShadows { get; set; } | Gets or sets whether this geometry can cast shadow |
| ControlPoints { get; } | Gets all control points |
| Deformers { get; } | Gets all deformers associated with this geometry. |
| Edges { get; } | Gets edges of the Mesh. Edge is optional in mesh, so it can be empty. |
| Excluded { get; set; } | Gets or sets whether to exclude this entity during exporting. |
| virtual Name { get; set; } | Gets or sets the name. |
| ParentNode { get; set; } | Gets or sets the first parent node, if set the first parent node, this entity will be detached from other parent nodes. |
| ParentNodes { get; } | Gets all parent nodes, an entity can be attached to multiple parent nodes for geometry instancing |
| PolygonCount { get; } | Gets the count of polygons |
| Polygons { get; } | Gets the polygons definition of the mesh |
| Properties { get; } | Gets the collection of all properties. |
| ReceiveShadows { get; set; } | Gets or sets whether this geometry can receive shadow. |
| Scene { get; } | Gets the scene that this object belongs to |
| VertexElements { get; } | Gets all vertex elements |
| Visible { get; set; } | Gets or sets if the geometry is visible |
Methods
| Name | Description |
|---|---|
| static DoBoolean(BooleanOperation, Mesh, Matrix4?, Mesh, Matrix4?) | |
| AddElement(VertexElement) | Adds an existing vertex element to current geometry |
| CreateElement(VertexElementType) | Creates a vertex element with specified type and add it to the geometry. |
| CreateElement(VertexElementType, MappingMode, ReferenceMode) | Creates a vertex element with specified type and add it to the geometry. |
| CreateElementUV(TextureMapping) | Creates a VertexElementUV with given texture mapping type. |
| CreateElementUV(TextureMapping, MappingMode, ReferenceMode) | Creates a VertexElementUV with given texture mapping type. |
| CreatePolygon(int[]) | Creates a new polygon with all vertices defined in indices. To create polygon vertex by vertex, please use PolygonBuilder. |
| CreatePolygon(int, int, int) | Create a polygon with 3 vertices(triangle) |
| CreatePolygon(int[], int, int) | Creates a new polygon with all vertices defined in indices. To create polygon vertex by vertex, please use PolygonBuilder. |
| CreatePolygon(int, int, int, int) | Create a polygon with 4 vertices(quad) |
| FindProperty(string) | Finds the property. It can be a dynamic property (Created by CreateDynamicProperty/SetProperty) or native property(Identified by its name) |

| GetProperty(string) | Get the value of specified property |
| GetVertexElementOfUV(TextureMapping) | Gets a VertexElementUV instance with given texture mapping type |
| IsManifold() | Check if current mesh is a manifold mesh. This function will not cache the manifold calculation result. |
| Optimize(bool) | Optimize the mesh’s memory usage by eliminating duplicated control points |
| Optimize(bool, float, float, float) | Optimize the mesh’s memory usage by eliminating duplicated control points |
| RemoveProperty(Property) | Removes a dynamic property. |

Examples
To add a polygon in mesh:
Mesh mesh = new Mesh();
int[] indices = new int[] {0, 1, 2};
mesh.CreatePolygon(indices);
Travel through all polygons in mesh:
Mesh mesh = new Mesh();
foreach(int[] polygon in mesh)
{
//deal with polygon
}
