class Disc

package h3d.prim

extends Polygon › MeshPrimitive › Primitive

Static methods

staticdefaultUnitDisc():Disc

Get a default unit Disc with radius = 0.5, segments = 8, thetaStart = 0.0, thetaLength = Math.PI * 2 and add UVs to it. If it has not be cached, it is cached and subsequent calls to this method will return Disc from cache.

Constructor

@:value({ thetaStart : 0.0, segments : 8, radius : 0.5 })new(radius:Float = 0.5, segments:Int = 8, thetaStart:Float = 0.0, ?thetaLength:Float)

Variables

read onlyradius:Float

read onlysegments:Int

Methods

Inherited Variables

Defined by Polygon

Defined by Primitive

buffer:Buffer

The primitive vertex buffer, holding its vertexes data.

@:value(-1)forcedLod:Int = -1

Allow user to force a specific lod index. If set to -1, forced lod will be ignored.

indexes:Indexes

The primitive indexes buffer, holding its triangles indices.

@:value(0)read onlyrefCount:Int = 0

Current amount of references to this Primitive. Use incref and decref methods to affect this value. If it reaches 0, it will be atuomatically disposed.

Defined by Primitive

decref():Void

Decrease reference count of the Primitive. If recount reaches zero, Primitive is automatically disposed when last referencing mesh is removed from scene.

getMaterialIndexes(material:Int):{start:Int, count:Int}

Returns the number and offset of indexes for the specified material

incref():Void

Increase reference count of the Primitive.

lodCount():Int

Return the LOD count.

screenRatioToLod(screenRatio:Float):Int

selectMaterial(material:Int, lod:Int):Void

Select the specified sub material before drawin. Used for internal usage.

toString():Null<String>

Return the primitive type.
