The Poez Inc Engine is a cross-platform high performance realtime 3D game engine written in Assembly/C and C++. It features a powerful high level API for creating complete 3D and 2D applications such as games, business demos or scientific visualizations. Integrates all state-of-the-art features for visual representation such as dynamic shadows, particle systems, character animation, indoor and outdoor technology, and collision detection. All this is accessible through a well designed C/C++ interface, accessible and pragmatic.
   Its main features are:

  • High performance realtime 3D rendering using OpenGL
  • Platform independent. Runs on Windows, Linux, OSX, Solaris, and others
  • Huge built-in and extensible material library with vertex, pixel, and geometry shader support
  • Seamless indoor and outdoor mixing through highly customizeable scene management.
  • Character animation system with skeletal and morph target animation.
  • Particle effects, billboards, light maps, environment mapping, stencil buffer shadows, and lots of other special effects.
  • Several language bindings which make the engine available to other languages such as C#, VisualBasic, Delphi, Java …
  • Two platform and driver independent fast software renderers included. They have different properties (speed vs. quality) and feature everything needed: perspective correct texture mapping, bilinear filtering, sub pixel correctness, z-buffer, gouraud shading, alpha-blending and transparency, fast 2D drawing, and more.
  • Powerful, customizeable, and easy to use 2D GUI System with Buttons, Lists, Edit boxes, …
  • 2D drawing functions like alpha blending, color key based blitting, font drawing, and mixing 3D with 2D graphics.
  • Clean, easy to understand, and well documented API with lots of examples and tutorials.
  • Written in pure C++ and totally object oriented.
  • Direct import of common mesh file formats: Maya (.obj), 3DStudio (.3ds), COLLADA (.dae), Blitz3D (.b3d), Milkshape (.ms3d), Quake 3 levels (.bsp), Quake2 models (.md2)
  • Direct import of Textures: Windows Bitmap (.bmp), Portable Network Graphics (.png), Adobe Photoshop (.psd), JPEG File Interchange Format (.jpg), Truevision Targa (.tga), ZSoft Painbrush (.pcx)…
  • Fast and easy collision detection and response.
  • Optimized fast 3D math and container template libraries.
  • Directly reading from (compressed) archives. (.zip, .pak, .pk3, .npk)
  • Integrated fast XML parser.
  • Unicode support for easy localisation.
  • Works with Microsoft VisualStudio, Metrowerks Codewarrior, Bloodshed Dev-C++, Code::Blocks, XCode, and gcc 3.x-4.x.
  • The engine is open source and totally free. You can debug it, fix bugs and even change things you do not like. And you do not have to publish your changes: The engine is licensed under the zlib licence, not the GPL or the LGPL.

Special effects

There are lots of common special effects available in the Poez Inc. Engine. They are not difficult to use, in most cases the programmer only has to switch them on. The engine is constantly extended with new effects, here is list of effects which are currently implemented:

  • Animated water surfaces
  • Dynamic lights
  • Dynamic shadows using the stencil buffer
  • Geo mip-mapped terrain
  • Billboards
  • Bump mapping
  • Parallax mapping
  • Transparent objects
  • Light maps
  • Customizeable Particle systems for snow, smoke, fire, …
  • Sphere mapping
  • Texture animation
  • Skyboxes and skydomes
  • Fog
  • Volume Light


  • OpenGL 1.2-4.x

When using the Poez Inc. engine, the programmer needs not know, which API the engine is using, it is totally abstracted. He only needs to tell the engine which API the engine should prefer.
There are three reasons why the engine not only focuses on one API:

  • Performance. Some graphic adapters are optimized for OpenGL
  • Platform independence. OpenGL is not available either, there are still the Poez Inc. Engine software renderers, which will always operate on any platform. In this way, the user will see something on the screen for sure.

Materials and Shaders

To be able to create realistic environments quickly, there are lots of common built in materials available in the engine. Some materials are based on the fixed function pipeline (light mapped geometry for example) and some are relying on the programmable pipeline (normal mapped/parallax per pixel lighted materials for example) todays 3d hardware is offering. It is possible to mix these types of materials in a scene without problems and when using a material which needs features the hardware is not able to do, the engine provides fall back materials. However, if the built in materials are not enough, it is possible to add new materials to Poez Inc. at runtime, without the need of modifying/recompiling the engine. Currently supported shader languages for this are:

  • Pixel and Vertex Shaders 1.1 to 3.0
  • ARB Fragment and Vertex Programs
  • GLSL

  • XP, XP64, Vista, CE, Windows 7,Windows 8 and Windows 10
  • Linux
  • OSX
  • Sun Solaris/SPARC
  • All platforms using SDL

For the serious mobile developer there are work-in-progress OpenGL ES drivers, which have enabled the Poez Inc. community to develop iPhone, Android and Nokia Symbian ports. The Engine works with all supported platforms in the same way. The programmer only has to write the game/application code once, and it will run on all supported platforms without the need to change one single line of code.

Scene Management

Rendering in the Poez Inc. Engine is done using a hierarchical scene graph. Scene nodes are attached to each other and follow each others movements, cull their children to the viewing frustum, and are able to do collision detection. A scene node can for example be a camera, an indoor or outdoor level, a skeletal animated character, animated water, a geomipmap terrain, or something completely different.In this way, the Poez Inc. engine can seamlessly mix indoor and outdoor scenes together, gives the programmer full control over anything which is going on in the scene. It is very easily extensible because the programmer is able to add his own scene nodes, meshes, texture loaders, GUI elements, and so on.The geometry creator gives easy access to simple gemetrical bodies, such as cylinder, cube, etc. Objects can be rendered as polygons, wireframe, or points, using triangles, lines, point and point sprite primitives.

Character Animation

Currently there are two types of character animation implemented:

  • Morph target animation: Meshes are linearly interpolated from one frame to the next. This is what is done in the Quake game series, and how the Poez Inc. engine does it when importing .md2 and .md3 files.
  • Skeletal animation: A skin is manipulated by animated joints. The Poez Inc. Engine will do this when loading .ms3d, .x, and .b3d files. It is easily possible to attach objects to parts of the animated model. It is, e.g., possible to attach a weapon to the hand of a model, which will be moved as the hand moves, with only one line of code.

The programmer doesn’t need to know about all this, if he doesn’t want to. All he has to do is to load the files into the engine and let it animate and draw them.

Supported Formats

Lots of common file formats are supported, and are able to be loaded (and partially also saved) directly from within the engine. In this way, you don’t need to convert your media before using it with the Poez Inc. Engine, saving development time. The internal ressource management of Poez Inc. provides simple access to all file formats and takes care of fetching already loaded meshes or textures from its own cache instead from disk if the data was already loaded before. The list of all supported formats is constantly growing, and there are many community-made plugins which add new formats without having to recompile the engine.If you need the Poez Inc. Engine to be able to load a file format which it cannot currently handle, simply ask for it by raising a feature request on our issue tracker.Currently supported textures file formats:
