The LOD (level of detail) fade modes. Modes other than LODFadeMode.None will result in Unity calculating a blend factor for blending/interpolating between two neighbouring LODs and pass it to your shader.
None | 指示 LOD 淡化已关闭。 |
CrossFade | 如果与摄像机之间的距离处于由每个 LOD 的 LOD.fadeTransitionWidth 指定的范围内,则在当前 LOD 与下一个 LOD 之间执行交叉淡入淡出样式混合。 |
SpeedTree | 通过指定此模式,LODGroup 会执行 SpeedTree 样式 LOD 淡化方案:对于最后一个(最粗略)网格 LOD 以外的所有网格 LOD,淡化系数会计算为对象当前屏幕高度的百分比(与 LOD 的整个范围相比)。如果摄像机正好处于上一个 LOD 切出的位置处,则为 1,如果下一个 LOD 恰好即将切入,则为 0。对于最后一个网格 LOD 和公告牌 LOD,使用交叉淡入淡出模式。 |
