Detailed Description

This is the base class for plugins which perform tone mapping operations in 3ds Max.

The tone mapping process

Renderers typically perform lighting simulation in physical space, using units like candelas or watts to represent the intensity of light. If they do not strictly use physical units, they will at least perform calculations in linear space. Rendered images, however, are typically expressed in RGB space (usually sRGB), which is usually non-linear. The purpose of the tone operator (or tone mapper) is to transform linear, physical quantities into (potentially non-linear) RGB values. This process is similar to what happens when photographic film or sensors convert photons into colors (either chemically or electronically).
The physical scale

The physical scale is used to reconcile physical and non-physical light sources in a scene; it defines the equivalence between a photometric light that emits in candelas and a standard light that emits in arbtrary units. For example, a physical scale of 1500 would cause a non-physical emissive surface with a value of PI (3.1416) to emit 1500 cd/m^2. The physical scale affects environment lighting as well; non-physical envrionment lighting will be affected in the same way.

The tone operator expects that all physical values be pre-divided by the physical scale. That is, any value fed to ScaledToRGB() is expected to be expressed in candela/physical_scale. The physical scale therefore adjusts physical values, rather than non-physical ones, in order to preserve compatibility with legacy features that were implemented before the concept of physical units was introduced to 3ds Max. The ToneOperator will multiply any values fed to ScaledToRGB() by the physical scale to undo this division.
Inverse tone mapping

The process of converting an RGB value back into physical quantities is called inverse tone mapping. This process is especially useful when rendering with a backgorund or environment image which is already expressed in non-linear, RGB values. The image in question must first be inverse-tone-mapped to ensure that, once it goes through the rendering and tone mapping processes, it looks exactly as it did originally. Ideally, all environment images fed to the renderer should be expressed in physical, linear quantities - but that is not always possible.

◆ Update() [1/2]

virtual void Update ( const TimeValue  t,
INode *const  cameraNode,
const IPoint2 renderResolution,
const float  pixelAspectRatio,
Interval validity 
)
pure virtual

Initializes the tone operator at the given time, and with the given camera & view options.

This method needs to be called before any ToneOperator functionality is used - for example, before ScaledToRGB() is called. It enables the ToneOperator to initialize itself with the given view parameters, as well as cache data which would be costly to compute for every pixel. Using the tone operator without previously calling this method will result in incorrect tone mapping: the parameters being used may not be updated for the correct time or camera.

Parameters
tThe time at which the tone operator is to be evaluated.
cameraNodeThe camera node being used for rendering. The tone operator is free to affect the tone mapping process based on the camera parameters.
renderResolutionThe resolution being rendered, used to determine the position in raster space when calling ScaleToRGB().
pixelAspectRatioThe pixel aspect ratio, which can be used to derive an image aspect ratio.
[in,out]validityThe validity of the parameters which were evaluated by the call.

◆ Update() [2/2]

virtual void Update ( TimeValue  t,
Interval valid 
)
pure virtual

Initializes the tone operator at the given time, but without any information w.r.t.

the view and camera. Consequently, some features may not be available.

Instead, whenever possible, use: virtual void Update(const TimeValue t, INode* const cameraNode, const IPoint2& renderResolution, const float pixelAspectRatio, Interval& validity)

Reimplemented from SpecialFX.

◆ BuildMaps()

bool BuildMaps ( TimeValue  t,
RenderMapsContext rmc 
)
inlinevirtual

This method is called for the operator to do any work it needs to do prior to rendering.

Rendering using the RenderMapsContext uses the identity tone operator.

Remarks
This method is called for the operator to do any work it needs to do prior to rendering. You may use this method to perform a subrender to sample the rendered output for histogramming or automatic exposure.
Parameters
tThe time at which the rendering is taking place.
rmcThe context of the map rendering.
Returns
True means this method succeeded. False means it didn't. This method should return false if it the sub-render fails or if it can't allocate memory or some other error occurs. If BuildMaps returns false, the render is aborted.
116 {
117  return true;
118 }

◆ SubRenderSample()

void SubRenderSample ( float  energy[3])
inlinevirtual

This method is called during subrenders to give the tone operator a chance to sample the image with full dynamic range.

If your operator needs to sample the image, you can set a flag so you know when you are sampling.

121 {
122 }

◆ ScaledToRGB() [1/4]

virtual void ScaledToRGB ( float  energy[3],
const Point2 xyCoord 
) const
pure virtual

Scales a value from physical space to RGB space.

Rendered images, as directly output by renderers, will store values in physical units (candelas per meter-squared) which must be transformed into RGB space before they can be viewed on a monitor. This method performs this transformation.

Parameters
[in,out]energyThe physical RGB value, which gets converted in-place into an RGB value.
xyCoordThe x/y coordinate of the pixel being scaled, the valid range being [0, renderResolution] (renderResolution having been passed to Update()).

◆ ScaledToRGB() [2/4]

virtual float ScaledToRGB ( float  energy,
const Point2 xyCoord 
) const
pure virtual

Scales a grayscale value from physical space to RGB space.

See also

Parameters
[in,out]energyThe physical RGB grayscale value, which gets converted in-place into an RGB grayscale value.
xyCoordThe x/y coordinate of the pixel being scaled, the valid range being [0, renderResolution] (renderResolution having been passed to Update()).

◆ ScaledToRGB() [3/4]

virtual void ScaledToRGB ( float  color[3]) const
pure virtual

Equivalent of virtual void ScaledToRGB(float energy[3], const Point2& xyCoord) const, but without any support for view-dependent tone mapping.

◆ ScaledToRGB() [4/4]

) const
pure virtual

For a full description of the physical scale, see the details description for class ToneOperator.

Parameters

validThe validity of the physical scale value is intersected into this interval.

◆ SetPhysicalUnit()

virtual void SetPhysicalUnit ( float  value,
TimeValue  t

Sets the physical scale to be used when rendering.

For a full description of the physical scale, see the details description for class ToneOperator.

Parameters
valueThe new physical scale.
tThe time at which to set the new physical scale.

◆ ScalePhysical() [1/2]

virtual void ScalePhysical ( float  energy[3]) const
pure virtual

Scale physical values so they can be used in the renderer.

The first version of the method converts a color value and the second converts a monochrome value. The converted color value is stored in energy. The converted monochrome value is returned. This method assumes that Update has been called to cache the various values needed by the tone operator. By using a float array to pass in color values, we can use the same routine to handle the various classes used to store color information, for example, Color, AColor and Point3. The red, green and blue components are stored in that order in the array.

Remarks
This method is used to scale a physical color value so it may be used in the renderer.

This method assumes that Update has been called to cache the various values needed by the tone operator.

Note: By using a float array to pass in color values, we can use the same routine to handle the various classes used to store color information, for example, Color, AColor and Point3.
Parameters
energyThe input and output (converted) color value. The colors are stored as red=energy[0], green=energy[1], and blue=energy[2].

◆ ScalePhysical() [2/2]

virtual float ScalePhysical ( float  energy) const
pure virtual

Grayscale version of virtual void ScalePhysical(float energy[3]) const.

◆ ScaleRGB() [1/2]

virtual void ScaleRGB ( float  color[3]) const
pure virtual

Scale RGB values, just supplied to invert ScalePhysical.

The first version of the method converts a color value and the second converts a monochrome value. The converted color value is stored in energy. The converted monochrome value is returned. This method assumes that Update has been called to cache the various values needed by the tone operator. By using a float array to pass in color values, we can use the same routine to handle the various classes used to store color information, for example, Color, AColor and Point3. The red, green and blue components are stored in that order in the array.

Remarks
This method is called to scale RGB values (the inverse of ScalePhysical()).

This method assumes that Update has been called to cache the various values needed by the tone operator.
Parameters
colorThe input values to scale and storage for the output scaled values as well. The colors are stored as red=energy[0], green=energy[1], and blue=energy[2]. The output values are in the range 0-1.

◆ InverseMap() [1/4]

virtual void InverseMap ( float  rgb[3],
const Point2 xyCoord 
) const
pure virtual

Convers an RGB value back into physical space.

◆ AllocateThreadedProcessor()

virtual const ThreadedProcessor* AllocateThreadedProcessor ( ) const
pure virtual

Allocates an interface which enables processing of the tone operator from arbitrary (or multiple) threads.

Returns
A pointer to a newly allocated interface which is then owned exclusively by the caller. The caller is responsible for deleting the pointer once done. May return null if the tone operator doesn't implement support for the ThreadedProcessor interface, in which case the tone operator must be processed from the main thread, using ToneOperator::ScaledToRGB().
Remarks
This method may only be called from the main thread - as every other method in in this class.
The tone operator must be updated using ToneOperator::Update() before calling this method. The processor to be returned will reflect the parameter values setup by the last call to Update().
