🦗 Mantis Engine - Custom OpenXR Game Engine
Mantis Engine was a team project focused on building a custom C++ cross-platform game engine for Windows and OpenXR-based VR. The development of the engine spanned over 16 weeks, with an initial 8-week core engine phase by a team of five programmers. This article mainly focuses on this 8 week period.
Additionally, there was an 8-week production phase with an expanded multidisciplinary team, where the aim was to build a game (Ascension Protocol) with Mantis Engine. During this period the engine was expanded further to support that game’s specific needs.
