Could you build this?
No Real-time 3D heat simulation involves solving partial differential equations (the heat equation) across 3D meshes using numerical methods and GPU compute shaders.
What it would actually take: The system requires a finite element method (FEM) or discrete exterior calculus solver running on GPU compute shaders (WebGPU or HLSL/CUDA) to compute thermal diffusion across arbitrary 3D triangular meshes in real time. The hardest aspects are maintaining numerical stability under stiff boundary conditions, dynamic remeshing, and mapping surface temperature gradients accurately to visual spectrums at high framerates. This requires advanced numerical analysis, computational fluid/heat transfer physics, and graphics compute shader expertise.
