Could you build this?
No Developing custom 3D numerical physics simulations (SPH fluid dynamics, thermal convection, n-body gravity) and an unaccelerated terminal braille rasterizer demands deep computational math and systems graphics expertise.
What it would actually take: The engine requires low-level systems programming in Rust or C++ implementing numerical solvers (Verlet/Runge-Kutta), spatial data structures (Barnes-Hut octrees and BVH), and smoothed-particle hydrodynamics for fluids. Additionally, it requires a custom CPU-only software rasterizer implementing 3D projection, depth buffering, and glyph packing into Unicode braille 2x4 dot matrices to achieve 60 FPS in a terminal or via WASM. This necessitates specialized mathematical physics and graphics optimization skills.
