Table transfer function.
Library: ilvbmpflt
This transfer function defines a lookup table by a linear interpolation into a lookup table. Interpolation uses the following formula: k/N <= C <= (k + 1)/N => C' = vk + (C - k/N) * N * (vk+1 - vk)
IlvTableTransfer::IlvTableTransfer | ( | ) |
Constructor.
Initializes a new instance of the class IlvTableTransfer
.
Constructor.
Initializes a new instance of the class IlvTableTransfer
using a table.
length | The length of the table. |
values | An array of length floating point values. |
IlvTableTransfer::~IlvTableTransfer | ( | ) |
Destructor.
The destructor releases all the memory used by the instance.
Returns the table.
count | The number of values in the array. |
