OBJ-Parser

OBJ File parser loading Indexed Models and Materials

usage:

  OBJLoader loader("PATH TO LOAD");
  
  for (IndexedModel& model : loader.GetModels()) {
    
    //process Model
    
  }
}

OBJLoader:

class OBJLoader {
		OBJLoader(const String& fileName);  //Loades models from file : warning : large models can take a second or two

		Vector<IndexedModel> GetModels();
  };

IndexedModel:

  struct IndexedModel {
		String name;

		Material material;

		Vector<vec3> vertices;
		Vector<vec2> textures;
		Vector<vec3> normals;
		Vector<uint> indices;
	};

Material:

  struct Material
	{
		String MaterialName;

		vec3 AmbientColor;
		vec3 DiffuseColor;
		vec3 SpecularColor;

		float SpecularExponent;
		float OpticalDensity;
		float Dissolve;
		int Illumination;
	
		String AmbientTexture;
		String DiffuseTexture;
		String SpecularTexture;
		String SpecularHightlight;
		String AlphaTexture;
		String BumpTexture;
	};

dependancie: requires glm vor vec3, vec2 and optimized calculations

additional:

  template<typename T>
  class Vector : std::vector<T>

features:

  void swapRemove(int index);
  void insertEnd(Vector<T>& toInsert, const Vector<T>& data);
  bool containsAll(const std::vector<T>& o);
  bool contains(const T& val);

additional:

  class String : public std::string

features:

	static String Trim(const String& str, char c = ' ');
	static String TrimTail(const String& str, char c);

	static String ToString(glm::vec3 val);
