高达二阶的球谐函数(3 个波段,9 个系数)。
球谐函数 (SH) 表示各方向上的函数或信号,常在计算机图形中用于高效计算平滑光照。Unity 将它们用于 LightProbes 和环境光照。
L2 球谐函数由 9 个系数(用于每个颜色通道)组成。
另请参阅:RenderSettings.ambientMode、RenderSettings.ambientProbe、LightProbes。
this[int,int] | 访问各个 SH 系数。 |
AddAmbientLight | Add an ambient light to the spherical harmonics. |
AddDirectionalLight | Add a directional light to the spherical harmonics. |
Clear | Clears the spherical harmonics coefficients to zero. |
Evaluate | Evaluates the spherical harmonics for each given direction. The directions and results arrays must have the same size. |
operator != | Returns true if the spherical harmonics are different. |
operator * | 按给定系数缩放 SH。 |
operator + | Adds two spherical harmonics. |
operator == | Returns true if the spherical harmonics are equal. |
