GraphicsTrianglePath

Package | flash.display
Class | public final class GraphicsTrianglePath
Inheritance | GraphicsTrianglePath Object
Implements | IGraphicsPath, IGraphicsData

Defines an ordered set of triangles that can be rendered using either (u,v) fill coordinates or a normal fill. Each triangle in the path is represented by three sets of (x, y) coordinates, each of which is one point of the triangle.

The triangle vertices do not contain z coordinates and do not necessarily represent 3D faces. However a triangle path can be used to support the rendering of 3D geometry in a 2D space.

Property Detail

culling | property

`public var culling:String`

Specifies whether to render triangles that face in a given direction. Usually used to prevent the rendering of triangles that cannot be seen in the current view.

Can be set to any value defined by the TriangleCulling class.

indices | property |

`public var indices:Vector`

A Vector of integers or indices, where every three indices defines a triangle. If the indices parameter is null then every three vertices (six x,y pairs in the vertices Vector) defines a triangle. Otherwise each index refers to a vertex, which is a pair of numbers in the vertices Vector. For example `indices[1]` refers to (`vertices[2]`, `vertices[3]`).

uvtData | property |

`public var uvtData:Vector`

A Vector of normalized coordinates used to apply texture mapping. Each coordinate refers to a point on the bitmap used for the fill. There must be one UV or one UVT coordinate per vertex.

In UV coordinates, (0,0) is the upper left of the bitmap, and (1,1) is the lower right of the bitmap.

If the length of this vector is twice the length of the `vertices` vector then normalized coordinates are used without perspective correction.

If the length of this vector is three times the length of the `vertices` vector then the third coordinate is interpreted as 't', the distance from the eye to the texture in eye space. This helps the rendering engine correctly apply perspective when mapping textures in 3D.

vertices | property |

`public var vertices:Vector`

A Vector of Numbers where each pair of numbers is treated as a point (an x, y pair).

Constructor Detail

GraphicsTrianglePath | () | Constructor

`public function GraphicsTrianglePath(vertices:Vector = null, indices:Vector = null, uvtData:Vector = null, culling:String = "none")`

Creates a new GraphicsTrianglePath object.

Parameters

| `vertices:Vector` (default = `null`)`` — A Vector of Numbers where each pair of numbers is treated as a point (an x, y pair). Required.
| `indices:Vector` (default = `null`)`` — A Vector of integers or indices, where every three indices defines a triangle.
| `uvtData:Vector` (default = `null`)`` — A Vector of normalized coordinates used to apply texture mapping.
| `culling:String` (default = "`none`")`` — Specifies whether to render triangles that face in a given direction. Usually used to prevent the rendering of triangles that cannot be seen in the current view. Can be set to any value defined by the TriangleCulling class.
