Detailed Description

Generic interface to separable image reconstruction filters.

When resampling bitmaps or adding radiance-valued samples to a rendering in progress, Mitsuba first convolves them with a so-called image reconstruction filter. Various kinds are implemented as subclasses of this interface.

Because image filters are generally too expensive to evaluate for each sample, the implementation of this class internally precomputes an discrete representation (resolution given by MTS_FILTER_RESOLUTION)

Member Enumeration Documentation

enum mitsuba::ReconstructionFilter::EBoundaryCondition

When resampling data to a different resolution using Resampler::resample(), this enumeration specifies how lookups outside of the input domain are handled.

See Also

Resampler

Enumerator
EClamp	Clamp to the outermost sample position.
ERepeat	Assume that the input repeats in a periodic fashion.
EMirror	Assume that the input is mirrored along the boundary.
EZero	Assume that the input function is zero outside of the defined domain.
EOne	Assume that the input function is equal to one outside of the defined domain.
