A Soft Real-Time Concurrent Graphics Platform

Abstract

This article describes a language and framework that aims to ease soft real-time and concurrent programming for games. The defined language extends the standard C 99 language, adding some new constructions to it. Its standard library provides some graphical utilities for game development, object file loading, rendering optimization passes, built-in physical simulation, high-level collision detection, 3D audio and shader loading. It also provides basic concurrent programming structures and real-time support by some functions which changes real-time exception handling. This extension, CEx, was implemented as a extension of the Clang compiler that generates code for the Low Level Virtual Machine (LLVM). From this implementation, it was possible to provide an environment for game development, which comprehends the language, and an intermediary library for concurrency, real-time signals and graphics.
