Drome Engine is a 3D game engine written in C++ using OpenGL for graphics rendering. Some of its features include dynamic lightmaps, stenciled shadow volumes, particle effects, md2 model loading, PCX and PNG image loading, TrueType font loading, simple physics, and a Quake-style console.
DromeAudio is a small audio manipulation and playback library. It features a simple API for loading, generating, processing, and playing audio. Some of its features include loading and saving WAV sounds, loading Ogg Vorbis sounds, audio mixing/playback, and dynamic audio processing effects such as pitch shifting and echo.
Dwarf HTTP Server is a full-featured Web server with a Java Servlet API 2.2 implementation and JSP support. Since it is based on the Dwarf framework, it shares its common design principles: powerful security architecture, modularity and extensibility, XML-based configuration, uniform logging, and remote management.
Dwarf is a modular Java framework for developing network server applications based on Internet standards. While focused on building service-based applications like Web servers, mail servers, and messaging services, it can also be used for other applications. The core consists of several packages, which provide a multithreaded kernel, security based on the standard Java 2 Platform Security architecture and the JAAS, logging, configuration, and a management system. Modularity and a fine-grained API allow one to extend the server, to reuse the existing services for a new application, or even create new services based on the existing ones.
ENet for C# wraps the C-language ENet networking library. For games and other realtime applications, if you use TCP, old data can hold up newer data, even if it is no longer relevant (old positions, etc.). Your players will perceive any lost packet as a "lag burst". ENet supports multiple in-order streams of data, and allows you to decide on reliability on a per-packet basis. The library is useful for both client-server and peer-to-peer architectures.
