GPU 硬件加速光线追踪激光雷达微物理级仿真
基于 Vulkan 与 NVIDIA OptiX 硬件 BVH 树加速遍历内核，毫秒级解算多光束二次弹跳回波、雨雪尘埃大气粒子米氏散射及物体材质各向异性反射率 (BRDF)。
激光回波全脉冲时域数字化波形高保真建模
完整模拟雪崩光电二极管 (APD) 与跨阻放大器 (TIA) 的非线性饱和响应曲线，精准重现高反射率交通指示牌在激光直射下的强度光晕溢出与伪点云瑕疵伪影。
- Over 5,000,000 ray-triangle intersection tests per frame.
- Simulation of 905nm and 1550nm laser wavelengths.
- Accurate retroreflector bloom and beam divergence modeling.
- Bit-accurate output formatted as native Velodyne/Hesai/Ouster UDP packets.
