Definition at line 66 of file ps_float.h.

NL3D::CPSFloatGradient::CPSFloatGradient (  const float *  floatTab,
uint32  nbValues,
uint32  nbStages,
float  nbCycles = 1.0f
) 
 

Construct the value gradient blender by passing a pointer to a float table.

Parameters:
nbStages The result is sampled into a table by linearly interpolating values. This give the number of step between each value
nbCycles : The nb of time the pattern is repeated during particle life. see ps_attrib_maker.h
