BlendFunctionInterface

The function represented by maxon::BlendFunctionInterface is used with:

• maxon::BlendFunctionInterface::MapValue(): Returns the interpolation value for the given offset and border values.

  // This example samples the interpolation curve defined by the given blend function.
 
  // get BlendFunctionRef for EaseInOutQuad
  const maxon::BlendFunctionRef& easeInOut = maxon::BlendFunctions::EaseInOutQuad();
 
  // prepare sampling the function
 
  const maxon::Float step = 1.0 / maxon::Float(count);
  maxon::Float       pos  = 0.0;
 
  const maxon::Data min(0.0);
  const maxon::Data max(10.0);
 
  maxon::BaseArray<maxon::Float> values;
  values.EnsureCapacity(count) iferr_return;
 
  // sample the function
  for (maxon::Int i = 0; i < count; ++i)
  {
    const maxon::Data  res = easeInOut.MapValue(pos, min, max) iferr_return;
    const maxon::Float value = res.Get<maxon::Float>() iferr_return;
    values.Append(value) iferr_return;
 
    pos += step;
  }
 
  DiagnosticOutput("@", values);
