Detailed Description

class Preprocessor

Public Functions

Preprocessor(wchar_t const *output_file_name)

Creates the class object which handles OOC data processing.

Parameters

output_file_name – The name of the output file, also used as the basis for accessory file and folder names.

~Preprocessor()

PreprocessStatus Run()

Old-style data conversion. Given input “PointCloud” file(s), and any desired special options, reads the input and processes it into a spatial tree, writing the output .ooc and associated files) at the end.

void Initialize()

Prepares the starting spatial tree.

size_t AddPoints(size_t count, float const *points, float const *intensities = nullptr, unsigned char const *colors = nullptr)

Add points to the spatial tree.

Parameters

• count – The number of points being added.

• points – The single-precision point data, [3*count] float values

• intensities – Optional. Intensity values associated with the points, [count] float values.

• colors – Optional, RGB color values associated with the points, [3*count] unsigned char values.

Returns

the number of points actually added (options may filter input points).

size_t AddPoints(size_t count, double const *dpoints, float const *intensities = nullptr, unsigned char const *colors = nullptr)

Add points to the spatial tree.

Parameters

• count – The number of points being added.

• dpoints – The double-precision point data, [3*count] double values

• intensities – Optional. Intensity values associated with the points, [count] float values.

• colors – Optional, RGB color values associated with the points, [3*count] unsigned char values.

Returns

the number of points actually added (options may filter input points).

PreprocessStatus Export()

Finalizes any spatial tree processing and exports data to the .ooc and accessory files.
