Build Instructions

Ubuntu

1. Clone project to desired location
2. Open terminal and navigate to project folder
3. mkdir build
4. cd build
5. cmake ..
6. make
7. cd bin
8. run the demo of choice (ie for "Demo 1" call: ./demo1)

Windows

Prepatory Steps

1. Download GLEW, GLFW, GLM, FreeImage, and Assimp binaries for Visual Studio
2. Create the following folders:

• C:\Program Files\lib
• C:\Program Files\include

3. Copy the library (lib and dll) files to C:\Program Files\lib. (i.e. C:\Program Files\lib\assimp.lib) (see note)
4. Copy the include directory contents to C:\Program Files\include (ie. C:\Program Files\include\assimp). (see second note)

Note: If on a 64 bit system use the 64 bit libraries. Note: The header file for FreeImage does not have a sub-folder and goes directly in the include folder.

Building

1. Clone project to desired location
2. Open project folder in Explorer
3. Create a new directory named build
4. Open CMake GUI
5. Set the source directory to the project root
6. Set the build directory to the directory created in step 3
7. Configure using Visual Studio 2015
8. Once configuration completes press "Generate"
9. After generation completes press "Open Project"
10. Set the demo of choice as the startup project (ie demo1)
11. Build
12. It will fail to run however as it will complain that Assimp and FreeImage are missing
13. Copy assimp.dll and FreeImage.dll (from the prep steps) to bin/Debug (in build)
14. Copy the directory bin/res to bin/Debug (resulting in bin/Debug/res)
15. Open the properties of the project you want to run
16. Go to the debugging item in "Configuration Properties"
17. Change the working directory to: $(SolutionDir)/bin/Debug
18. Run the application

Note: If creating a release build than replace all instances of Debug with Release.

Demo Previews

Demo 1 - Simple Blinn-Phong Renderer

Renders models as solid gray objects that are lit using the Blinn-Phong shading method. There are no controls.

Demo 2 - Texture Mapping

Rendering a box with a diffuse, specular, and normal map. There are no controls.
