Futz

Verb. futz (around) with, to handle or deal with, especially idly, reluctantly, or as a time-consuming task

Oh my. You've found Futz. This is a super casual, hobby project. I am making a cross-platform, 3D engine in my spare time. As one does. Also, its main target is the Dreamcast.

How's it going?

Not bad, thanks for asking. It's been a fun exercise so far.

Futz has platform (input and rendering) abstraction layers which allow it to run on:

• Dreamcast
• SDL1 (Windows, Mac, Linux)
• SDL2 (Windows, Mac, Linux)
• GLUT (Windows, Mac, Linux)
• Android
• iOS

However, only SDL2 and Dreamcast are regularly tested.

What can it do?

Futz is C++ that compiles into a library for other C++ programs to use. It provides game engine features like:

• Vector, Matrix and Quaternion classes and operations
• 3D model, vertex color and texture loading and rendering (Waveform OBJ format)
• Input abstraction
• A component/entity system for creating game entities and attaching properties and logic
• A scenegraph for storing and manipulating references to entities
• Transparent and opaque render queues
• Depth sorting of transparent entities
• Build-in component types:
  • Axis Aligned Bounding Box
  • Bounding Box
  • Bounding Sphere
  • Box Collider
  • Draw Axis
  • Draw Model
• A camera class

Example Code

Here's a snippit of what it looks like to load and place a model.

void Demo::MyStartFunction(){
 // Get a reference to the futz singleton
 Futz* futz = Futz::Instance(); 

 // Create a blank node to hold our spaceship
 Node* spaceship = new Node();

 // Load a 3d model
 char* file = (char*)"assets/taxi_model.obj";
 spaceship = futz->LoadModel(file);
 spaceship->Load();

 // Position, rotate and scale the ship
 spaceship->transform.SetPosition(0, 10, 0);
 spaceship->transform.SetRotation(90, 0, 0);
 spaceship->transform.scale = 1;

 // Add it to the scene
 futz->scene.AddNode(spaceship);
}

Compiling tips

Warning! Several of the demos are out of date. Only expect src/demo to compile currently!

Windows

Should build with Visual Studio 2017. Compiled demo and life binaries need to execute in a path along with a 32bit SDL2.dll and their assets folder.

Unix

You'll need some dev libraries like SDL2 installed on your system. Make sure src/futz/bin exists.

#compile futz. SDL2 is the most recently tested
~/Documents/git/futz/src/futz$ make sdl2

src/demo works with SDL2. At least on linux and dreamcast right now.

~/Documents/git/futz/src/demo$ make LAYER=SDL2
