Synopsis

A c3d format file viewer created under Qt environment.

Code Example

// /* Templates */ //

namespace sys_endian {

const unsigned one = 1U;

inline bool little_endian() {
    return reinterpret_cast<const char*>(&one) + sizeof(unsigned) - 1;
}

inline bool big_endian() {
    return !little_endian();
}

} //sys_endian

//SwapEndian template T swapEndian(const T numIn) { T numOut; int size = sizeof(T);

char* numToConvert = (char*) & numIn;
char* numToReturn = (char*) & numOut;

for(int i = 0, j = size-1; j >= 0; i++, j--)
    numToReturn[i] = numToConvert[j];

return numOut;

}

//SwapEndian template T returnByte(const T numIn, const int bit) { T numOut;

int size = sizeof(T);

char* numToConvert = (char*) & numIn;
char* numToReturn = (char*) & numOut;

for(int i = 0; i < size; i++)
     numToReturn[i] = 0;

numToReturn[0] = numToConvert[bit-1];

return numOut;

}

//ReadWord template void readWord(T* word, const int bytes, FILE* file) { char* wordToRead = (char*) word;

if((int)sizeof(T) > bytes)
    for(int i = 0; i < bytes; i++)
        wordToRead[i+1] = 0;

for(int i = 0; i < bytes; i++) {
    wordToRead[i] = 0;
    fread(&wordToRead[i], 1, 1, file);
}

}

//ReadWordWithEndian template void readWordWithEndian(T* word, const int bytes, FILE* file, const int endian_flag) { char* wordToRead = (char*) word;

if((int)sizeof(T) >= bytes)
    for(int i = 0; i < bytes; i++)
        wordToRead[i+1] = 0;

if(endian_flag == SAME_ENDIAN)
    for(int i = 0; i < bytes; i++) {
        fread(&wordToRead[i], 1, 1, file);
    }
else if(endian_flag == DIFF_ENDIAN) {
    if(bytes > SIZE_8_BIT)
        for(int i = bytes-1; i >= 0; i--) {
            wordToRead[i] = 0;
            fread(&wordToRead[i], 1, 1, file);
        }
    else
        for(int i = 0; i < bytes; i++) {
            wordToRead[i] = 0;
            fread(&wordToRead[i], 1, 1, file);
        }
}

}

Motivation

This project created as my Diploma Project for graduating from Rural Surveying of National Technical University of Athens. http://www.survey.ntua.gr/en/

Installation - Compilation

1)Open the project with QtCreator 2)Build 3)Run

Tests

This program can read almost every c3d file.
