inviwo::DataMapper Class Reference

Map values into data or value ranges. Data range refer to the range of the data type, i.e. [0 4095] for 12-bit unsigned integer data. Value range refer to the physical meaning of the value, i.e. Hounsfield value range is from [-1000 3000]. It is important that the data range is specified for data types with a large range (for example 32/64-bit float and integer) since the data is often normalized to [0 1], when for example performing color mapping, i.e. applying a transfer function.

Detailed Description

Map values into data or value ranges. Data range refer to the range of the data type, i.e. [0 4095] for 12-bit unsigned integer data. Value range refer to the physical meaning of the value, i.e. Hounsfield value range is from [-1000 3000]. It is important that the data range is specified for data types with a large range (for example 32/64-bit float and integer) since the data is often normalized to [0 1], when for example performing color mapping, i.e. applying a transfer function.
