KCC_LemniscateTrap
public KCC_LemniscateTrap(Generic pparent)
- constructor
KCC_LemniscateTrap
public KCC_LemniscateTrap()
Init
public void Init(complex pz)
- call this before each sequence of values to be trapped
- Overrides:
Init
in class KCC_PlaneCurveTrapBase
Iterate
public float Iterate(complex pz)
- call this for each iteration being trapped
- Overrides:
Iterate
in class KCC_PlaneCurveTrapBase
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 KCC_PlaneCurveTrapBase
- Returns:
- the texture value for the last point used (i.e. call GetTextureValue() after calling Iterate(), not before)
