away3d.materials.compilation.MethodDependencyCounter - Away3D API Reference

MethodDependencyCounter keeps track of the number of dependencies for "named registers" used across methods. Named registers are that are not necessarily limited to a single method. They are created by the compiler and passed on to methods. The compiler uses the results to reserve usages through RegisterPool, which can be removed each time a method has been compiled into the shader.

Constructor

`new()`

Creates a new MethodDependencyCounter object.

Variables

`read onlyglobalPosDependencies:Int`

`read onlynormalDependencies:Int`

`read onlyprojectionDependencies:Int`

`read onlysecondaryUVDependencies:Int`

`read onlytangentDependencies:Int`

`read onlyusesGlobalPosFragment:Bool`

`read onlyuvDependencies:Int`

`read onlyviewDirDependencies:Int`

Methods

`addWorldSpaceDependencies(fragmentLights:Bool):Void`

Adds any external world space dependencies, used to force world space calculations.

`includeMethodVO(methodVO:MethodVO):Void`

Increases dependency counters for the named registers listed as required by the given MethodVO.

Parameters:

`methodVO`	the MethodVO object for which to include dependencies.

`reset():Void`

Clears dependency counts for all registers. Called when recompiling a pass.

`setPositionedLights(numPointLights:Int, lightSourceMask:Int):Void`

Sets the amount of lights that have a position associated with them.

Parameters:

`numPointLights`	The amount of point lights.
`lightSourceMask`	The light source types used by the material.
