MMF_TrapModeSmoothClosest

public MMF_TrapModeSmoothClosest()

Method Detail

Init

public void Init(complex pz)

Description copied from class: MMF_TrapModeSmoothWithThreshold

call this at the beginning of each sequence

Overrides:

Init in class MMF_TrapModeSmoothWithThreshold

Parameters:

pz - the initial z value

Iterate

public void Iterate(complex pz,
                    complex pzt,
                    float pdistance,
                    float ptexture)

Description copied from class: MMF_TrapModeSmoothWithThreshold

call this for each point

Note that derived functions should always copy all used parameters to the "old" versions when they are changed as here.

m_wastrapped should be set to true in the derived function when the main (current) values get changed

Overrides:

Iterate in class MMF_TrapModeSmoothWithThreshold

Parameters:

pz - the z value

pzt - the transformed z value

pdistance - the trap distance

ptexture - tyhe texture value

OldResult

public void OldResult()

Description copied from class: MMF_TrapModeSmoothWithThreshold

call this to compute penultimate results

This should only be called after previously calling Result() and getting the actual result value using the Trap Color Mode since the original result values are destroyed by this call.

Overrides:

OldResult in class MMF_TrapModeSmoothWithThreshold
