Join Pablo Colapinto for an in-depth discussion in this video Cleaning up the code: Make a texture struct, part of Up and Running with OpenGL.
-I'd like to show you how we can encapsulate some of the…functionality we've been discussing in this chapter,…by using some hpp header files.…Drag in the include folder from the example files folder.…Let's take a look at GL texture.hpp.…GL texture hpp encapsulates in its init…method a generation and binding of a GL text image 2-D.…
It defaults to using GLRGBA as the format…and GL float as the type.…If you'd like to use this class to import…bitmaps for instance, you need to change…this to GLRGB and the type to GL unsigned byte.…You'd also want to change GL text subimage 2-D…to use GLBGR and GL unsigned byte here.…Let's also take a look at GLMesh.hpp.…GLMesh.hpp attempts to encapsulate some of the…vertex binding that we've discussed so far.…
It has a vertex data structs that contains…all the attributes we've been using…position, normal, color and texture coordinate,…along with built-in methods to access…their memory offsets within the struct.…Then there's a Mesh struct which contains a vect 3…holding its position in world space, and something…

Q: Why am I getting errors saying I don’t have GLEW installed when I try to create the Xcode projects with Cmake?
1) Download, Install, and Run Xcode
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
brew install glew
./bootstrap && make && make install
brew install cmake
cd Exercise Filesmkdir xcodecd xcodecmake -G "Xcode" ..
