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[currentIndexsize+3]=(i+1)/(float)subdsU; pBuffer[currentIndexsize+4]=j/(float)subdsV; currentIndex++; pPrimitiveBuffer->unlock();
src\engine\geometry\subds\SubDsGeometry.cpp(37) src\engine\geometry\SkinnedMeshGeometry.cpp(45)
pBuffer[isize+0]=m_ct[0]->m_pColors[i3];
pBuffer[isize+1]=m_ct[0]->m_pColors[i3+1];
pBuffer[isize+2]=m_ct[0]->m_pColors[i3+2];
