1 GENERAL INFORMATION

Duplicated source code blocks can harm maintainability of software systems.
Duplo is a tool to find duplicated code blocks in large C, C++, Java, C# and 
VB.Net systems.

- Sample output snippet -
...
src\engine\geometry\simple\TorusGeometry.cpp(56)
src\engine\geometry\simple\SphereGeometry.cpp(54)
	pBuffer[currentIndex*size+3]=(i+1)/(float)subdsU;
	pBuffer[currentIndex*size+4]=j/(float)subdsV;
	currentIndex++;
	pPrimitiveBuffer->unlock();

src\engine\geometry\subds\SubDsGeometry.cpp(37)
src\engine\geometry\SkinnedMeshGeometry.cpp(45)
    pBuffer[i*size+0]=m_ct[0]->m_pColors[i*3];
    pBuffer[i*size+1]=m_ct[0]->m_pColors[i*3+1];
    pBuffer[i*size+2]=m_ct[0]->m_pColors[i*3+2];
...
