constructor

KCC_SpheroidsTrap

public KCC_SpheroidsTrap()

Method Detail

Init

public void Init(complex pz)

call this before each sequence of values to be trapped

Overrides:

Init in class TrapShape

Iterate

public float Iterate(complex pz)

call this for each iteration being trapped

Overrides:

Iterate in class TrapShape

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)
