I was very disappointed as it cant debug/profile OpenGL/CUDA/CL applications on same machine.

Good question to fail ;)

External properties for classes (C++)

Once working on some MMO project based on Reality Engine. Engine has Actor class and its derivatives. Each of them has some amount (> 10) of properties (scale, color, ...). As we had big word (MMO game!) so smooth and fast loading was very important. But I noticed that engine spend some significant memory and loading time on creation abstract class properties.
Lets do some calculations - when need to load 100 Actors its allocate 100*10 = 1000 properties, each property has std::string for it's name and another std::string for description. So loading 100 Actors involves ~3000 additional allocations.

As engine uses that properties them for xml serialization and Editor bindings it was impossible to easily remove them....
That project was closed ^( due to economical crisis.
But recently I got flashback and decide that will be useful to use it in some of my pet projects.

So here is draft version of external properties:

Windows UI evolution

VS11 for graphics programmer

Enhancements for Game Development:
* Viewing and basic editing of 3D models
* Viewing and editing of images and textures with support for alpha channels and transparency
* Visually designing shader programs and effect files. (!)
* Debugging and diagnostics of DirectX based output.
Also some smart code analyzers added...
NICE!

C++ trick

const T& get() { const static T empty_value; return condition ? real_value : empty_value;}

it's helpful when T is std::container or so on.

RGDEngine + OpenGL

I'm start working on Linux/OpenGL (ES) support in RGDEngine (http://rgdengine.googlecode.com) Involves new shader material system and (I hope) iPhone and Android support.
