Gwin3D Freeware Game/3D graphics/Media/Networking/Image C++ class library

Welcome to the GWin3D^TM home page

GWin3D is a freeware C++ game/simulation class library for Windows (Win32) that provides real-time full-featured 3D graphics, fast networking, multimedia, 2D image manipulation, and/or wave capture and playback. It includes over 400 class methods described in detail in the included 200-page developer's manual. Click here to view the manual online (650K).

Most tasks can be accomplished in their basic form by simply linking with the library, instantiating a class, and then calling a member function or two. For examples...

Playing a media file takes 2 lines of code
Loading an image file, accessing its pixels, and saving it in another file format takes 3 lines of code
Loading a 3D model and displaying it in a window takes 6 lines of code
Sending a UDP packet takes 2 lines of code
Recieving a UDP packet takes 2 lines of code
Capturing wave data, modifying it, and playing it back takes 8 lines of code.
Applying an AVI movie to a 3D object (as a texture) takes 3 lines of code

GWin3D can be used with most Win32 C++ development environments with little or no tweaking, including all versions of Visual Studio, the free Borland tools, and GNU C++. The freeware GWin3D is fully functional and contains NO adware or spyware of any kind.

GWin3D provides:

Bare-bones sample source code showing how to accomplish some of the most common tasks with just a few lines of code.
Object oriented design that vastly minimizes application coding, yet still allows easy access to low-level functionality when needed. This includes access to all low-level automatically-enabled performance functionality, APIs, handles, OpenGL rendering contexts, socket handles, etc.
Easy but powerful 3D Graphics, including loading of VRML model files (such as those created by Blender--an open-source professional modeler), automatic and infinite level of detail (LOD), auto-texturing of models, 3D object (sprite) tree heirarchies, automatic depth buffer optimization, automatic out-of-view culling, 3D object proximity/collision/mesh surface detection, animated movie textures from an AVI file or from individual images, planar shadows of 3D objects, flat or spherical 3D heightfields and meshes created dynamically or from image files for creating 3D radiation patterns, terrains, etc.
Fast and easy networking, including vastly simplified raw UDP communication, fast UDP-based data sharing, UDP broadcasting, LAN and Internet peer-to-peer connections, NAT router hole punching, and TCP clients (HTTP, FTP, telnet, etc.)
Audio and video multimedia, including WAV, MP3, AVI, MPEG, wave sample capture and play, and AVI video frame access.
2D image file access and creation that includes support for alpha channels, direct pixel access, conversion to texture (applied to the surface of a 3D object), heightfields (conversion to flat or spherical meshes), DIBs, variable compression, and reading and writing of JPG, BMP, and JPEG2000 (JP2) format files.

*See the Terms before downloading or using GWin3D. Here is the GWin3D SDK (zip file 700K), which includes the GWin3D redistributable DLL, the import library, header file, and the programmer's manual. Release notes are available here.
