apitrace vs Orx

apitrace records OpenGL, Direct3D and DirectDraw API calls in trace files for replay and examination. Recorded calls can be replayed on another machine; OpenGL traces can also be replayed across operating systems. Its tools let users inspect graphics state and call data, view framebuffers and textures, edit trace files and profile performance. Coverage varies across APIs and operations: the feature matrix spans OpenGL 1.0–4.5, OpenGL ES 1.0–3.0, Direct3D 7–11.x and DirectDraw. Command-line profiling can capture frame, GPU, CPU and pixels-drawn data, with shader-profile formatting available through a script. The operating-system matrix lists Linux, OS X and Windows for tracing, replay, command-line and GUI use. Windows and Linux binaries are available for x86_64 and Arm64, with Windows x86 binaries also provided. The open-source project is licensed under MIT. One stated limitation is that programmatic Direct3D capture interfaces are unsupported. The maintainer says patches, issues and requests are handled as time permits, and the project links to a manual, bug-reporting guide, source-hacking guide, wiki and mailing list.

Orx is a free, open-source 2.5D game development engine for C and C++ programmers. Its templated, data-driven configuration can define objects and scenes, and changes can be made without recompiling. The engine includes accelerated rendering, sprite batching, multiple cameras and viewports, custom shaders, off-screen rendering, and multiple render targets. Audio capabilities include 3D sound and music, recording, filters, and controls for volume, pitch, and stereo balance. Orx also provides collision handling, rigid-body physics with joints, and input for keyboard, joystick, mouse, and touch. Data-driven animation graphs and event management cover clocks, effects, input, physics, shaders, sound, spawners, and timelines. Localization can select language-specific images, text, and sounds while a game runs. A plugin architecture supports customization and porting. Target platforms include Windows, Linux, macOS, Web/HTML5, Android, and iOS. The zlib license permits free use and modification in freeware and commercial projects. Learning resources include tutorials, examples, setup and beginner guides, and configuration information.
