Member Function Documentation

◆ GetClassID()

Class_ID GetClassID ( )
inlinestatic

Returns the class ID for the physical camera plugin.

32 {
33  return Class_ID(0x46697218, 0x28e8008d);
34 }
Definition: maxtypes.h:154

◆ GetFilmWidth()

virtual float GetFilmWidth ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the width of the film plane, in system units.

The height is derived from the aspect ratio of the image to be rendered.

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetEffectiveLensFocalLength()

virtual float GetEffectiveLensFocalLength ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the effective focal length of the lens, in system units.

Remarks
This value may be different from the focal length specified by the user; when focusing, the lens may move thus affecting its effective focal length and the resulting field of view. This returns the result of such movement - the distance between the film plane and the lens.
The crop zoom factor is not taken into account by this method (see GetCropZoomFactor()).
Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetCropZoomFactor()

virtual float GetCropZoomFactor ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the crop zoom factor of the lens.

This feature behaves as an image crop. As such, it effectively increases the lens focal length for purposes of calculating the field-of-view. However, exposure and depth of field are not affected. To achieve this, exposure is performed using the f-number (see GetLensApertureFNumber()), while depth of field is performed using the absolute aperture radius relative to the non-zoomed lens (see GetLensApertureRadius()).

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetLensApertureRadius()

virtual float GetLensApertureRadius ( const TimeValue  t,
Interval validity,
const bool  adjustForBlades 
) const
pure virtual

Returns the absolute aperture radius, in system units.

The aperture size affects depth of field (larger apertures result in amplified depth of field effect), as well as exposure (if specifying exposure manually through the ISO).

Remarks
When rendering a circular aperture, this is the radius of the disc. When rendering a bladed aperture, this is NOT the radius of the polygon: instead, the polygon should have an area which is equal to that of a disc with the given radius. This ensures that exposure is unaffected by the presence of blades (blades therefore have only an aesthetic property). When rendering a texture aperture, the texture will be remapped to a square with sides equal to twice the radius.
Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.
[in]adjustForBladesWhen true, and the aperture shape is set to bladed, the correct radius of the polygon will be returned instead of the radius of the disc. When false, the radius of the disc aperture is returned; as noted above, this radius cannot be used directly to generate a bladed polygon aperture.

◆ GetLensApertureFNumber()

virtual float GetLensApertureFNumber ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the aperture size as an f-number.

The aperture size affects depth of field (larger apertures result in amplified depth of field effect), as well as exposure (if specifying exposure manually through the ISO).

Remarks
When rendering a bladed aperture, the radius of the polygon should be adjusted such that the area of the polygon matches that of a disc at this aperture size; this ensures consistent exposure, see
See also
GetLensApertureRadius().
Note
The f-number returned here is relative to the focal length returned by GetEffectiveLensFocalLength(). It may therefore differ from the value supplied by the user, as it takes lens breathing into account. Lens breathing will cause the f-number to grow smaller as the lens focuses closer (though the absolute aperture radius doesn't change), thus affecting exposure.
Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetMotionBlurEnabled()

virtual bool GetMotionBlurEnabled ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns whether motion blur is to be enabled.

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetShutterDurationInFrames()

virtual float GetShutterDurationInFrames ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the shutter open duration, the units being frames at the current frame rate, as returned by GetFrameRate().

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetShutterOffsetInFrames()

virtual float GetShutterOffsetInFrames ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the shutter open offset, the units being frames at the current frame rate, as returned by GetFrameRate().

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetFocusDistance()

virtual float GetFocusDistance ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the distance at which the lens is focused, in system units.

Remarks
The focus distance is relative to the lens, which is positioned on the camera origin.
Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetEffectiveISO()

virtual float GetEffectiveISO ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the ISO to be used when rendering this camera.

This is not necessarily the ISO currently stored in the parameter block; it may be an ISO value derived from the target exposure value.

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetEffectiveEV()

virtual float GetEffectiveEV ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the EV to be used when rendering this camera.

This is not necessarily the EV currently stored in the parameter block; it may be an EV value derived from the target exposure value.

Remarks
The EV being returned is technically the "equivalent EV at ISO 100", such that increasing the ISO is correctly represented as decreasing the EV (thus making the image brighter). This differs from the standard definition of EV (which would have little use here), and is somtimes known as EV100.
Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetWhitePoint()

virtual Color GetWhitePoint ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the white point, to be used with exposure control.

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetExposureVignettingAmount()

virtual float GetExposureVignettingAmount ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the amount of vignetting in the exposure (darkening on the edges of the rendered image), as a non-negative value.

Returns 0 if vignetting is disabled.

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetDOFEnabled()

virtual bool GetDOFEnabled ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns whether depth of field effects are enabled.

If this returns false, then a pinhole camera should be rendered (everything will be in focus).

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetBokehShape()

virtual BokehShape GetBokehShape ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the shape of the bokeh to be rendered.

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetBokehNumberOfBlades()

virtual int GetBokehNumberOfBlades ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the number of blades to be rendered, if GetBokehShape() returns BokehShape::Bladed.

This is the number of sides to the regular polygon.

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetBokehBladesRotationDegrees()

virtual float GetBokehBladesRotationDegrees ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the rotation of the aperture, if GetBokehShape() returns BokehShape::Bladed.

The regular polygon rendered for a bladed aperture should be rotated by this angle.

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetBokehTexture()

virtual Texmap* GetBokehTexture ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the texture to be used as the aperture shape, if GetBokehShape() returns BokehShape::Texture.

The aperture texture is specified as a transparency map: white means fully transparent, black means opaque. Colors also work and will tint the result. A texture that contains a white circle, over a black background, that runs to the edges of the texture, should render identically to a circular aperture. The texture will be fit into a square which's side has length equal to the diameter of the circular aperture (twice the radius returned by GetLensApertureRadius()).

Remarks
If no texture is specified, a circular aperture should be used as a fallback. If the texture cannot be loaded or is invalid (all black), then DOF should be disabled.
Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetBokehTextureAffectExposure()

virtual bool GetBokehTextureAffectExposure ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns whether the texture aperture shape should affect the exposure.

If true, then the aperture shape provided in the texture will affect exposure: a texture with a small white circle will result in a darker image than a texture with a larger white circle. If false, the aperture texture should not impact the overall exposure (though it will certainly impact local exposure): the overall exposure should be compensated such that it is equivalent to a circular aperture.

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetBokehOpticalVignetting()

virtual float GetBokehOpticalVignetting ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the amount of optical vignetting to be rendered.

Optical vignetting is also know as the cat's eye effect; it is caused by the presence of multiple element in the lens, with multiple circular elements combining to form a shape resembling the pupil of a cat's eye. Values typically range from -1.0 to 1.0, though values outside this range are valid but will produce heavy vignetting. The algorithm to generate the effect is as follows:

Point2 film_point = raster space coordinate in [-1,1], with y being scaled according to the image aspect ratio
Point2 aperture_point = sampled point on aperture in [-1,1]
float distance = distance_between_points(aperture_point, film_point * optical_vignetting_amount)
if(distance > 1.0)
reject sample
Definition: point2.h:44
Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetBokehCenterBias()

virtual float GetBokehCenterBias ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the amount of center bias to be rendered.

Center bias is used to generate a non-uniform aperture, with positive values biasing towards a ring shape and negative values biasing towards the center.

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetBokehAnisotropy()

virtual float GetBokehAnisotropy ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the amount of anisotropy present in the bokeh.

Anisotropy is used to simulate (apparent) non-circular apertures such as is produced by anamorphic lenses. Positive values stretch the bokeh along X, while negative values stretch along Y. The algorithm for generating this effect is as follows:

Point2 aperture_sample_point = point being sampled on the aperture
if(bokeh_anisotropy > 0.0f)
{
const float aniso = 1.0f / (1.0f - bokeh_anisotropy);
aperture_sample_point.x *= aniso;
aperture_sample_point.y /= aniso;
}
else
{
const float aniso = 1.0f / (1.0f + bokeh_anisotropy);
aperture_sample_point.x /= aniso;
aperture_sample_point.y *= aniso;
}
float y

float x

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetLensDistortionType()

virtual LensDistortionType GetLensDistortionType ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the type of lens distortion to be used.

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetLensDistortionCubicAmount()

virtual float GetLensDistortionCubicAmount ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the amount of distortion to be rendered, if GetLensDistortionType() returns LensDistortionType::Cubic.

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetLensDistortionTexture()

virtual Texmap* GetLensDistortionTexture ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the texture to be used, if GetLensDistortionType() returns LensDistortionType::Texture.

Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetFilmPlaneOffset()

virtual Point2 GetFilmPlaneOffset ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the offset to be applied to the image on the film plane.

The value is expressed as a ratio of the film plane width: a value of 1.0 with a film width of 36mm results in an offset of 36mm - or, if the X resolution were 640, an offset of 640 pixels. On the Y axis, the scale is also relative to the film plane width, such that the offset in real-world space is equally scaled in X or Y. The offset in pixels is therefore calculated as follows:

  • for X, it is: film_plane_offset.x * resolution.x
  • for Y, it is: film_plane_offset.y * resolution.y * image_aspect_ratio, or: film_planet_offset.y * resolution.x * pixel_aspect_ratio
    Parameters
    tThe time at which to retrieve the property value.
    [in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

◆ GetFilmPlaneOffsetInPixels()

Point2 GetFilmPlaneOffsetInPixels ( const IPoint2 resolution,
const float  pixelAspectRatio,
const TimeValue  t,
Interval validity 
) const
inline

Returns the offset to be applied to the image on the film plane, in pixels.

Whereas GetFilmPlaneOffset() returns the offset as a resolution-indepent value, this method resolves the actual raster-space offset, but requires the resolution to be given to it.

Parameters
resolutionThe resolution of the image to be rendered.
pixelAspectRatioThe pixel aspect ratio of the image to be rendered.
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.

int x
Definition: ipoint2.h:37
virtual Point2 GetFilmPlaneOffset(const TimeValue t, Interval &validity) const =0
Returns the offset to be applied to the image on the film plane.

◆ GetTiltCorrection()

virtual Point2 GetTiltCorrection ( const TimeValue  t,
Interval validity 
) const
pure virtual

Returns the tilt to be applied to the lens.

The value is to be applied as follows, where ray_target is the destination of point of the camera ray onto the focus plane (in camera space):

Point2 tilt = GetTiltCorrection(t, validity);
ray_target.x /= sqrt(1.0 + square(tilt.x);
ray_target.y /= sqrt(1.0 + square(tilt.y);
ray_target.z -= (ray_target.x * tilt.x) + (ray_target.y * tilt.y);
virtual Point2 GetTiltCorrection(const TimeValue t, Interval &validity) const =0
Returns the tilt to be applied to the lens.
Parameters
tThe time at which to retrieve the property value.
[in,out]validityThe validity of the returned value is intersected into the input value of this parameter.
