Billboard sprites are not rendering for some reason.. I believe this is a shader issue.

The engine needs a way to load in pre-made scenes from some sort of scene file. Let's go ahead and attempt to use the JSON Scene Description Language as described here:

http://area.autodesk.com/blogs/chris/json-scene-description-language

Rename shader files to <purpose>_<type>.glsl

Where <purpose> is a short description of the shader's purpose and <type> is one of fs,vs,gs etc.

This seems to be a more common industry standard.

Right now, all properties of an object are defined by subclassing (is-a relationships)

In order to clean up the codebase a litle, I would like to implement a component based architecture instead (has-a relationships).

See http://en.wikipedia.org/wiki/Composition_over_inheritance for more details

Models should not be specified manually in the code.. bleh! They should be loaded from model files.. let's go ahead and JSONify the wavefront OBJ format.

The engine is currently relying on platform provided OpenGL headers to compile. These vary wildly between operating systems and make compilation impossible on windows. I'd like to use glbinding to access the OpenGL API.

The camera should be guided on the edge of an invisible sphere, with the center of the sphere being the object that the camera is looking at.

• Holding the middle mouse button should enable the user to drag the camera along the surface of the sphere. The mouse moving in the X direction should move the camera along the longitude of the sphere, and the mouse moving in the Y direction should move the camera along the latitude of the sphere
• The mouse wheel should make the sphere larger or smaller
• Holding shift + the middle mouse button should move the camera on a plane tangental to the sphere at the point the camera is at.

In the shader cleanup, something broke with the grid rendering. Let's enable it and make it toggleable via some sort of shortcut. perhaps Alt+G

It should be possible to easily render text strings.

In order to facilitate this, I'll use fontstash with a custom rendering backend that ties into the engine's object and shader manager.
