Title : Actions
|
||||
Author: Edward R. Gonzalez
|
||||
|
||||
Description:
|
||||
This was a little experiment of mine to mess with action binding...
|
||||
|
||||
Allows for non-member functions to be binded to an action, implements a functioning queue as well.
|
||||
|
||||
TODO: Possibly add support for member functions. Have it so that deduction of delegate typef is not required to add to queue properly (right now it does, see input procedure for example);

Title : Execution
|
||||
Author: Edward R. Gonzalez
|
||||
|
||||
Description:
|
||||
This brings together the functionality I made in DGL and the Actions libraries to produce an OpenGL Workspace.
|
||||
|
||||
Currently the workspace is heavily hardcoded and has one light rotating around the specified object. The material for the object is set during prep as well.
|
||||
|
||||
All exposed library references are inside the inline namespace right after declaring the namespace execution.
|
||||
|
||||
After I have the global objects used, followed by the functionality implementations, and at the very end the main function running the default execution implementation.
