; Initialisation of the texture variables.<p>
; This is designed to be called once per change of texture, so normally
; just once say in a global section or in a constructor but it could be
; recalled if initiators were included in the class that could be set up
; in the constructor and modified later - allowing reconfiguration of the fBm.
; <p>The initialisation is done here (in it's own function) instead of in the
; constructor mainly so that it's possible to avoid the init when texturing
; is disabled at run time e.g.<br>
; if @fBm<br>
; GlobalInit(value)<br>

; want to initiate based on an external value.<br>

public MMF_AltfBm(Generic pparent)
pparent - the parent, generally "this" for the parent, or zeropublic MMF_AltfBm()
| Method Detail |
|---|
public void GlobalInit(complex pz)
This is designed to be called once per change of texture, so normally just once say in a global section or in a constructor but it could be recalled if initiators were included in the class that could be set up in the constructor and modified later - allowing reconfiguration of the fBm.
The initialisation is done here (in it's own function) instead of in the
constructor mainly so that it's possible to avoid the init when texturing
is disabled at run time e.g.
if @fBm
GlobalInit(value)
endif
Here pz is actually unused but is included in case derived functions
want to initiate based on an external value.
pz - a complex value for initialisation of the fBmpublic float GetfBm(complex pz)
pz - the z value for which to get an fBm value
