Detailed Description

SPH fluid simulation with raylib visualization.

Dam-break scenario: fluid falls onto a hot sphere (90 degC) and a cold sphere (0 degC). Heat diffuses between particles and exchanges with rigid bodies.

Controls: SPACE – pause / resume R – reset to initial state LMB drag – spawn cool water particles (20 degC) RMB drag – spawn hot water particles (85 degC) +/- – increase / decrease simulation speed (substeps per frame) ESC – quit
