Brahma is a 3D game engine with a rather retrofuturistic design, intended for small studios and solo developers. It's being written from scratch in C++ using standard Windows API and no third-party libraries. This technology introduces an entirely new class of low-latency real-time engines that make special timing requirements, treating frames as video fields with a target time budget of 2-4 ms each, down from 16-33 ms frame budgets normally seen in game engines. It evolves in a different way than other modern engines, rejecting conventional BSP, Z-buffer, floating-point coordinates, and most of the lame screen-space effects in favor of innovative and efficient techniques. The engine is non-Euclidean capable to some degree; also it supports true displacement mapping for sectors as a means to virtualize geometry that affects collisions. The engine is also carefully designed to be easy and convenient to develop for, yet versatile and adaptive to any needs.
I was testing my map editor on some of the projects from the past.
Any map effects, be it doors, switches, stairs etc. are to be handled by special controller objects. Controllers are invisible and abstract from actual map objects, but they can be linked with anything and potentially form dependency chains or feedback loops.
The only controllers currently supported are player spawn points and so-called dynamic-link portals. The latter represents a flexible tool for connecting maps of an episode with each other seamlessly. It has been prototyped for Build map import and creates dynamic portals for unpaired wall hitags of 256 or greater, which can be dynamically configured from the command line.
