Member Function Documentation

static Lut3DTransformRcPtr OCIO_NAMESPACE::Lut3DTransform::Create ( )

Create an identity 3D-LUT of size 2x2x2.

static Lut3DTransformRcPtr OCIO_NAMESPACE::Lut3DTransform::Create ( unsigned long  gridSize)

Create an identity 3D-LUT with specific grid size. Will throw for grid size larger than 129.

virtual bool OCIO_NAMESPACE::Lut3DTransform::equals ( const Lut3DTransform other) const
pure virtualnoexcept

Checks if this exactly equals other.

virtual void OCIO_NAMESPACE::Lut3DTransform::setFileOutputBitDepth ( BitDepth  bitDepth)
pure virtualnoexcept

Get the bit-depth associated with the LUT values read from a file or set the bit-depth of values to be written to a file (for file formats such as CLF that support multiple bit-depths). However, note that the values stored in the object are always normalized.

virtual void OCIO_NAMESPACE::Lut3DTransform::setGridSize ( unsigned long  gridSize)
pure virtual

Changing the grid size will reset the LUT to identity. Will throw for grid sizes larger than 129.

pure virtual
virtual void OCIO_NAMESPACE::Lut3DTransform::setValue ( unsigned long  indexR,
unsigned long  indexG,
unsigned long  indexB,
float  r,
float  g,
float  b 
pure virtual

Set the values of a 3D-LUT. Will throw if an index is outside of the range from 0 to (gridSize-1).

The LUT values are always for the "forward" LUT, regardless of how the transform direction is set.

These values are normalized relative to what may be stored in any given LUT files. For example in a CLF file using a "10i" output depth, a value of 1023 in the file is normalized to 1.0. The values here are unclamped and may extend outside [0,1].
