Structure • A little history of 0 A.D. • Used technologies and how it works. • Known problems. • Current solutions. • Future plans. Vladislav Belov 0 A.D: Graphics
History 0 A.D. (pronounced “zero-ey-dee”) is a free, open-source, historical Real Time Strategy (RTS) game currently under development by Wildfire Games, a global group of volunteer game developers. As the leader of an ancient civilization, you must gather the resources you need to raise a military force and dominate your enemies. 0 A.D. has been in development since 2001 (or 2003, depending on how you count). You can find complete history of the game at: https://play0ad.com/about/the-story-of-0-a-d/. Vladislav Belov 0 A.D: Graphics
Technologies • Own game engine - Pyrogenesis (written in C++). • SDL for most OS depended things (IO events, system calls, etc). • OpenGL 1/2 API for rendering some stuff: glBegin , glEnd , ... . • ARB/GLSL for shaders (ARB - 2002). Vladislav Belov 0 A.D: Graphics
Problems • Inaccurate hardware information. • Old OpenGL and slow API functions. • No modern OpenGL API functions: glDrawInstanced , ... . • Driver or application crashes on Intel cards with particular driver • Legacy support of OpenGL drivers on macOS 10.14 Vladislav Belov 0 A.D: Graphics
Solutions • Tracker and forum to collect people feedback. • In-game crash dump and system info that players can upload on our site. • A feedback server to receive automatic hardware reports voluntarily submitted by players of 0 A.D. Vladislav Belov 0 A.D: Graphics
Plans • Find out active audience that really play the game. • More abstractions to minimize number of places with direct low-level calls. • Find a low-level third party library or engine for GL/Vulkan/Metal. • White lists for drivers with bugs (like it’s done for Chromium).
