I think I have now I nice, minimal, decoupled implementation for integration between target texture, framebuffer (viewport + framebuffer) and renderer:

struct ctexture {
    char name[MAX_NAME_LENGTH];
    uint64_t hash;
    uint32_t id;
    GLuint texture_gl_id;
    ...
};

struct cframebuffer {
    char name[MAX_NAME_LENGTH];
    uint64_t hash;
    uint32_t id;
    GLuint framebuffer_gl_id;
    /* Viewport */
    GLfloat x;
    GLfloat y;
    GLfloat width;
    GLfloat height;
    GLfloat near;
    GLfloat far;
    GLfloat field_of_view;
    /* Target texture */
    uint32_t texture_id;
    ...
};

struct crenderer {
    char name[MAX_NAME_LENGTH];
    uint64_t hash;
    uint32_t id;
    /* Renderer customization */
    void *data;
    /* Target framebuffer */
    uint32_t targets[RENDERER_MAX_TARGETS];
    bool (*on_render)(crenderer *);
    void (*on_free)(crenderer *);
};

I'm currently in school, but I'm working with a few friends and we are developing a 3D survival type game with a post apocalyptic setting in which the world is overgrown with plant life and new and diverse species, however, you spawn on a space station in which you have to grab supplies and evacuate, so you are very new to the ground. In this world, there will be corrupt machine life and mutants that have adapted to the surroundings, but there will also be plenty of diverse wildlife and small tribes in which you can try to survive with or against. Weapons like guns and machinery will be very rare, and even if you do get yours hands on guns there will be low bullet supply adding a need to be careful with your bullet spending.

On the spaceship itself, there will be 4 stations in which you can scavenge materials from. You may only choose one out of the four to give yourself an advantage, you may also only take a limited number of items. If you spawn with multiple characters (Multiplayer function), they can choose a separate station. The stations we have in mind are Mechanics/Engineering(Blueprints, Vehicle parts, and a choice of a minirobot(it can be accessed later in the game wihout choosing this station), Agriculture(The basic necessities to start off in the farming direction, an abundance of starting food, and basic tools to terraform the world to your own), Supply Depot(The area where you have all of the extra supplies such as melee weapons, bullets, guns, wires, wood, and other basic components needed to construct buildings or other needed tools), and lastly, Medical(Choice of medkits, the components to build potions and herbs in order to survive, and even a (Possible) boost to health and regen). After choosing a station you have a minute or so to scavenge and then return to the dropship within your station and drop to the earth.

Then with the supplies you must build, survive, and strive within the new ground. There will also be "Rad Zones" which have higher zones of radiation which will have better materials and harder creatures, but will not be accessible until you research suits that can withstand radiation to a certain degree.

Well that's all I got right now. We are well on our way with making the basis of the spacestation, and will be making a blog with developer upsates soon!

Tl;dr: A post-apocalyptic survival game in first person with diverse plant life and creatures in which you start with an advantage of your choice(Engineering, Medicine, Agriculture, or Supplies)

Wow, I enjoyed looking at everyone's stuff, lots of talent and so proud to be apart of this community.

So many excellent looking projects here!

Here's mine: day job - programmer at a medium-small North Finland game studio, mostly HTML5 and Unity projects these days.

Current active hobby project - Steel Ranger, a Turrican / Metroid inspired scifi action-adventure for the Commodore 64. Now at the point of designing the game world layout, with an aim to get about 500 screens total. The basic game engine, player movement, player weapons and world tilesets are already done. I also maintain a mostly technical and sparsely updated development diary for it.

Now that is Sexy.
