worldbenchmark/PerfectPhysics

PerfectPhysics是一个评估world模型和视频生成是否符合已知物理常数和定律的测试套件。它包含了从运动物理（如重力、抛体运动）到流体动力学（如粘度、流体运动）的精选物理实验。每个场景都有初始上下文帧，并要求模型生成未来帧，以估计生成的视频中的核心物理常数，如重力加速度、粘度、摩擦等。

PerfectPhysics is an evaluation suite that assesses how well world models and video generations adhere to known physics constants and laws. It includes curated physics experiments ranging from motion physics (e.g., gravity, projectile motion) to fluid dynamics (e.g., viscosity, fluid motion). Each scenario provides initial context frames and requires the model to generate subsequent frames to estimate core physics constants such as gravitational acceleration, viscosity, friction, etc., from the generated videos.
