public static void DrawTexture3DSlice(Texture texture, Vector3 slicePositions, FilterMode filterMode = FilterMode.Bilinear, bool useColorRamp = false, Gradient customColorRamp = null);参数
| texture | 要绘制的体积纹理。 |
| slicePositions | 纹理采样平面的位置。 |
| filterMode | 设置要使用的纹理过滤模式。 |
| useColorRamp | 启用颜色渐变可视化。 |
| customColorRamp | Unity 用作颜色渐变的自定义渐变。如果未指定，Unity 使用 Google Turbo 颜色渐变。 |
描述
