|
- Class name: SaltLayerExtractor
|
|
- Category: SALT/Scheduling/Parallax Motion
|
|
- Output node: False

SaltLayerExtractor节点专门用于从一组动画层中提取特定层的数据，重点关注视差运动调度。它处理输入的动画层，生成缩放、x和y值的调度表，从而促进动态、多维动画的创建。
|
|
|
|
# Input types
|
|
## Required
|
|
- float_layers
|
|
- 这是一个动画层列表，每层包含缩放、x和y值的帧数据。该输入对于确定要提取和调度的特定层数据至关重要。
|
|
- Comfy dtype: LIST
|
|
- Python dtype: List[List[float]]
|
|
- layer_index
|
|
- 指定从提供的动画层列表中提取哪一层数据的索引。这允许有针对性地提取动画数据，从而精确控制视差运动的调度。
|
|
- Comfy dtype: INT
|
|
- Python dtype: int
|
|
|
|
# Output types
|
|
- zoom_schedule_lsit
|
|
- 从指定动画层提取的缩放值列表，用于调度视差运动中的缩放效果。
|
|
- Comfy dtype: LIST
|
|
- Python dtype: List[float]
|
|
- x_schedule_list
|
|
- 从指定动画层提取的x坐标值列表，用于调度视差运动中的水平移动。
|
|
- Comfy dtype: LIST
|
|
- Python dtype: List[float]
|
|
- y_schedule_list
|
|
- 从指定动画层提取的y坐标值列表，用于调度视差运动中的垂直移动。
|
|
- Comfy dtype: LIST
|
|
- Python dtype: List[float]
|
|
|
|
|
