MT_TextureBlock

public MT_TextureBlock()

Method Detail

Init

public void Init(complex pz)

Description copied from class: TrapShape

call this before each sequence of values to be trapped

Overrides:

Init in class TrapShape

Iterate

public float Iterate(complex pz)

Description copied from class: TrapShape

call this for each iteration being trapped

Overrides:

Iterate in class TrapShape

GetTransformedPoint

public complex GetTransformedPoint()

Description copied from class: TrapShape

Get transformed point.

Some trap modes and trap coloring modes require access to the "transformed" point. This is the final point that is actually used by the trap shape class to test against the trap. For most trap shape classes this will be exactly the same as the pz passed into Iterate(), and those classes can use this base class functionality. However, some trap shape classes (e.g. TrapShapeMerge, TrapShapeBlock) perform some internal transformations on pz before passing it to the trap shape; this gives them the opportunity to call their trap shape's function to get the final transformed point.

Overrides:

GetTransformedPoint in class TrapShape

Returns:

the last transformed point used (i.e. call GetTransformedPoint() after calling Iterate(), not before)

GetTextureValue

public float GetTextureValue()

Description copied from class: TrapShape

Get texture value.

Ordinarily, a trap shape does not have a native texture (it is flat). Some formulas may pair trap shapes with trap textures, and may need more information about trap textures when trap shapes are nested via TrapShapeMerge. This function provides support for accessing texture information.

Overrides:

GetTextureValue in class TrapShape

Returns:

the texture value for the last point used (i.e. call GetTextureValue() after calling Iterate(), not before)
