Methods

bool saveToPlyFile(
    const std::string& filename,
    bool save_in_binary = false,
    const std::vector<std::string>& file_comments = std::vector<std::string>(),
    const std::vector<std::string>& file_obj_info = std::vector<std::string>()
    ) const

Saves to a PLY file.

Parameters:

filename	The filename to be saved.
file_comments	If provided (!=nullptr) the list of comment strings stored in the file will be returned.
file_obj_info	If provided (!=nullptr) the list of “object info” strings stored in the file will be returned.

Returns:

false on any error writing the file. To obtain more details on the error you can call getSavePLYErrorString()

std::string getSavePLYErrorString() const

Return a description of the error if loadFromPlyFile() returned false, or an empty string if the file was loaded without problems.
