Detailed Description

Stores the vertex/triangle data of a mesh in easily modifiable form - which can then be used to actually create or update a mesh.

Constructor & Destructor Documentation

MeshCreator()

UnityUtilities.MeshCreator.MeshCreator	(	int	estimatedTriangleCount,
		int	estimatedVertexCount
	)

Creates a new MeshCreator.

Parameters

estimatedTriangleCount	Used to create the initial size of the MeshTriangles list.
estimatedVertexCount	Used to set the initial size of the MeshVertices list.

Member Function Documentation

AddQuad()

void UnityUtilities.MeshCreator.AddQuad	(	MeshVertex	a,
		MeshVertex	b,
		MeshVertex	c,
		MeshVertex	d
	)

Adds two triangles forming a quad to the MeshCreator. Adds the vertices to the MeshCreator if they aren't already added.

Parameters

a	The first vertex in clockwise order.
b	The second vertex in clockwise order.
c	The third vertex in clockwise order.
d	The fourth vertex in clockwise order.

AddTriangle()

MeshTriangle UnityUtilities.MeshCreator.AddTriangle	(	MeshVertex	a,
		MeshVertex	b,
		MeshVertex	c
	)

Adds a triangle to the MeshCreator. Adds the vertices to the MeshCreator if they aren't already added.

Parameters

a	The first vertex in clockwise order.
b	The second vertex in clockwise order.
c	The third vertex in clockwise order.

Returns

The created triangle.

AddVertex()

MeshVertex UnityUtilities.MeshCreator.AddVertex

(

MeshVertex

vertex

)

Adds a vertex to the MeshCreator and assigns it a VertexIndex. If it already has a VertexIndex, this method does nothing.

Parameters

vertex

The vertex to be added.

Clear()

void UnityUtilities.MeshCreator.Clear

(

)

Clear the triangles and vertices.

CreateMesh()

Mesh UnityUtilities.MeshCreator.CreateMesh

(

)

Creates a new mesh and fills it via UpdateMesh.

Returns

The filled mesh.

UpdateMesh()

Mesh UnityUtilities.MeshCreator.UpdateMesh	(	Mesh	mesh,
		bool	updatePositions = true,
		bool	updateNormals = true,
		bool	updateColors = true,
		bool	updateUVs = true,
		bool	updateTriangles = true
	)

Takes an existing mesh previously created with CreateMesh or UpdateMesh and fills it with the data from this MeshCreator.

Parameters

mesh	The mesh to be updated.
updatePositions	Should the vertex positions be updated?
updateNormals	Should the vertex normals be updated?
updateColors	Should the vertex colors be updated?
updateUVs	Should the UVs be updated?
updateTriangles	Should the triangle composition be updated? This only needs to be called when you assigned new vertices to triangles, not when vertices changed their data internally. Calling this also triggers updating every other property.

Returns

The filled mesh.

Property Documentation

MeshTriangles

List<MeshTriangle> UnityUtilities.MeshCreator.MeshTriangles

get

The registered triangles. Use AddTriangle or AddQuad to add triangles.

MeshVertices

List<MeshVertex> UnityUtilities.MeshCreator.MeshVertices

get

The registered vertices. Use AddVertex to add a vertex. Content of existing vertices can be freely updated.

MeshVerticesCount

int UnityUtilities.MeshCreator.MeshVerticesCount

get

The amount of registered vertices.
