详细描述
The QPlaneGeometry class allows creation of a plane in 3D space.
The QPlaneGeometry class is most commonly used internally by the QPlaneMesh but can also be used in custom Qt3DRender::QGeometryRenderer subclasses.
属性
height : float
Holds the plane height.
访问函数:
| float | height() const |
| void | setHeight(float height) |
Notifier signal:
| void | heightChanged(float height) |
indexAttribute : Qt3DRender::QAttribute * const
Holds the geometry index attribute.
访问函数:
| Qt3DRender::QAttribute * | indexAttribute() const |
mirrored : bool
Controls if the UV coordinates of the plane should be flipped vertically.
This property was introduced in Qt 5.9.
访问函数:
| bool | mirrored() const |

normalAttribute : Qt3DRender::QAttribute * const
Holds the geometry normal attribute.
访问函数:
| Qt3DRender::QAttribute * | normalAttribute() const |
positionAttribute : Qt3DRender::QAttribute * const
Holds the geometry position attribute.
访问函数:
| Qt3DRender::QAttribute * | positionAttribute() const |
resolution : QSize
Holds the plane resolution.
访问函数:
| QSize | resolution() const |
| void | setResolution(const QSize &resolution) |
Notifier signal:

tangentAttribute : Qt3DRender::QAttribute * const
Holds the geometry tangent attribute.
访问函数:
| Qt3DRender::QAttribute * | tangentAttribute() const |
texCoordAttribute : Qt3DRender::QAttribute * const
Holds the geometry texture coordinate attribute.
访问函数:
| Qt3DRender::QAttribute * | texCoordAttribute() const |
width : float
Holds the plane width.
访问函数:
| float | width() const |
| void | setWidth(float width) |
Notifier signal:
