GoKawiilDeveloper details 'double headed stack allocator' technique from Surreal Software's cancelled game
A programmer who worked on animation systems for the cancelled open-world title 'This is Vegas' at Surreal Software (Midway Seattle) around 2010 describes a memory management technique called a stack allocator, also known as a bump allocator. The method pre-allocates a fixed block of memory and uses a simple integer pointer to track allocation and deallocation, replacing costly dynamic memory calls that had become a profiling bottleneck in per-frame animation blending.
