Assignment -

The goals of this assignment are to familiarize yourself with obj parser, the OpenGL command of the illumination, shading and texture mapping.

Part A: Obj Parser

Obj Parser will load a wavefront obj mesh file, compute the normal for each face and display it.

The obj mesh file format is described here. More obj mesh files may be found on the internet

Download objLoader.zip, cube.obj, teapot.obj and pig.obj
Compile, run and understand the code

Part B: Illumination and Shading

Based on the previous assignment, extend the system to support the following features:

Support for a light source.
Interactively turn light(s) on and off.
Support flat, Gouraud or Phong shading models. (Hint: In order to do Smooth/Gouraud shading, you need to provide the normal vector for each vertex using glNormal. The vertex normal can be computed as the average of all the faces/triangles adjacent to the current vertex as described in here).
interactive change the (RGB) values associated with the global ambient light.
interactive change the (RGB) values associated with the ambient, diffuse and specular component of the light sources.
interactive change the (RGB) values associated with the ambient, diffuse and specular material properties of the objects.

Part C: Texture Mapping

Download header file stb_image.h that read images to OpenGL textures
Read cube.obj and an image file (.jpg) as a texture (here are two sample images: checker-board, mandrill, you can also use any other images you like) , and render the object with the texture mapped.

The file submitted is only the criteria I have the files that are to be used to do the project. Thank you! These are all the files needed it, has to be done using GLFW in OpenGL. Read cube.obj and an image file (.jpg) as a texture (here are two sample images: checker-board, mandrill, you can also use any other images you like) , and render the object with the texture mapped.
