Struct Scene3d 

pub struct Scene3d {
    pub camera: Camera,
    pub light_rig: LightRig,
    pub backdrop: Option<Backdrop>,
}

三维场景（<a:scene3d>，OOXML CT_Scene3D）。

包含相机与光照，定义观察形状的虚拟 3D 环境。

Fields

camera: Camera

相机（必填，默认 orthographicFront）。

light_rig: LightRig

光照设备（必填，默认 balanced + t）。

backdrop: Option<Backdrop>

三维场景背景（<a:backdrop>，可选，TODO-050）。

定义 6 个背景平面（地板/墙壁/左/右/顶/底），启用的平面会渲染为可见的背景面。 None 表示不写出 <a:backdrop> 元素（与 Office 默认行为一致）。

Implementations

impl Scene3d

pub fn write_xml(&self, w: &mut XmlWriter)

写出 <a:scene3d>...</a:scene3d>。

元素顺序（OOXML CT_Scene3D）

<a:scene3d>
  <a:camera>...</a:camera>        ← 必填
  <a:lightRig>...</a:lightRig>    ← 必填
  <a:backdrop>...</a:backdrop>    ← 可选（TODO-050）
</a:scene3d>

Trait Implementations

impl Clone for Scene3d

fn clone(&self) -> Scene3d

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Scene3d

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Scene3d

fn default() -> Scene3d

Returns the “default value” for a type.

impl Eq for Scene3d

impl PartialEq for Scene3d

fn eq(&self, other: &Scene3d) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
