Paradise is our API (Application Program Interface) based on Windows95 which provides all services for rendering real time graphics and sound to create virtual worlds. Paradise is interfaced with DirectX via our Platform Abstraction Layer. All the engines are software implemented and only use Microsoft APIs for future hardware accelerator support. Paradise is written in C++ except critical parts written in Pentium and MMX assembler and optimized by hand. Voxels engine for natural landscape tiled data base Geometry interpolation.
