Cartoon mesh generation for secondary structure of proteins in C++

CPPCartoon

This is a tool to generate meshes of a cartoon for secondary structure of proteins.

Can be used as a library by calling computeCartoonMesh or as a standalone tool by calling the executable on a PDB file (see Example).

---

Secondary structure type code : 0 = COIL / 1 = HELIX / 2 = STRAND

---

• Example for the executable: ./cppCartoon 1kx2.pdb output.obj

• Example for the library : computeCartoonMesh(numberOfChains, (int *)numberOfResiduePerChain, (float *)CA_O_Positions, (char *)ssTypePerResidue);

• CA_O_Positions: The function expects 3 float + 3 float for each residue : one alpha carbon position and one oxygen position per residue

---

• OpenMP is used to compute each chain in parallel

• PDBs are parsed using CPDB parser : https://github.com/vegadj/cpdb

• This code is based on the algorithm from https://github.com/fogleman/ribbon
