- <h3>[property:Boolean matrixWorldNeedsUpdate]</h3>
|
|
|
- <p>
|
|
|
- When this is set, it calculates the matrixWorld in that frame and resets this property

- to false. Default is *false*.

- </p>
|
|
|
-
|
|
|
- <h3>[property:Matrix4 modelViewMatrix]</h3>
|
|
|
- <p>This is passed to the shader and used to calculate the position of the object.</p>
|
|
|
-
|
|
|
- <h3>[property:String name]</h3>
|
|
|
- <p>Optional name of the object (doesn't need to be unique). Default is an empty string.</p>
|
|
|
+ <h3>[property:Matrix4 matrix]</h3>
|
|
|
+ <p>局部变换矩阵。</p>
|
|
|
|
|
|
- <h3>[property:Matrix3 normalMatrix]</h3>
|
|
|
- <p>
|
|
|
- This is passed to the shader and used to calculate lighting for the object. It is the transpose of the inverse of the upper left 3x3 sub-matrix of this object's modelViewMatrix.<br /><br />
|
|
|
+ <h3>[property:Boolean matrixAutoUpdate]</h3>
|
|
|
+ <p>
|
|
|
+ 当这个属性设置了之后，它将计算每一帧的位移、旋转（四元变换）和缩放矩阵，并重新计算matrixWorld属性。默认值是[page:Object3D.DefaultMatrixAutoUpdate] (true)。
|
|
|
+ </p>
|
|
|
|
|
|
- The reason for this special matrix is that simply using the modelViewMatrix could result in a non-unit length of normals (on scaling) or in a non-perpendicular direction (on non-uniform scaling).<br /><br />
|
|
|
+ <h3>[property:Matrix4 matrixWorld]</h3>
|
|
|
+ <p>
|
|
|
+ 物体的世界变换。若这个Object3D没有父级，则它将和local transform [page:.matrix]（局部变换矩阵）相同。
|
|
|
+ </p>
|
|
|
|
|
|
- On the other hand the translation part of the modelViewMatrix is not relevant for the calculation of normals. Thus a Matrix3 is sufficient.
|
|
|
- </p>
|
|
|
+ <h3>[property:Boolean matrixWorldNeedsUpdate]</h3>
|
|
|
+ <p>
|
|
|
+ 当这个属性设置了之后，它将计算在那一帧中的matrixWorld，并将这个值重置为false。默认值为*false*。

- <h3>[property:function onAfterRender]</h3>
|
|
|
- <p>
|
|
|
- An optional callback that is executed immediately after the Object3D is rendered.
|
|
|
- This function is called with the following parameters: renderer, scene, camera, geometry,
|
|
|
- material, group.
|
|
|
- </p>
|
|
|
+ <h3>[property:Matrix4 modelViewMatrix]</h3>
|
|
|
+ <p>这个值传递给着色器，用于计算物体的位置。</p>
|
|
|
|
|
|
- <h3>[property:function onBeforeRender]</h3>
|
|
|
- <p>
|
|
|
- An optional callback that is executed immediately before the Object3D is rendered.
|
|
|
- This function is called with the following parameters: renderer, scene, camera, geometry,

|
|
- <p>Object's parent in the [link:https://en.wikipedia.org/wiki/Scene_graph scene graph]. An object can have at most
|
|
|
- one parent.</p>
|
|
|
+ <h3>[property:Matrix3 normalMatrix]</h3>
|
|
|
+ <p>
|
|
|
+ 这个值传递给着色器，用于计算物体的光照。
|
|
|
+ 它是物体的modelViewMatrix矩阵中，左上角3x3子矩阵的逆的转置矩阵。
|
|
|
+ <br /><br />
|
|
|
+ 使用这个特殊矩阵的原因，是只需使用modelViewMatrix就可以得出一个法线（缩放时）的非单位长度或者非垂直的方向（不规则缩放时）。
|
|
|
+ <br /><br />
|
|
|
+ 另一方面，modelViewMatrix矩阵中的位移部分和法线的计算无关，因此Matrix3就已经足够了。

- <h2>Static Properties</h2>
|
|
|
- <p>
|
|
|
- Static properties and methods are defined per class rather than per instance of that class.
|
|
|
- This means that changing [page:Object3D.DefaultUp] or [page:Object3D.DefaultMatrixAutoUpdate]
|
|
|
- will change the values of [page:.up up] and [page:.matrixAutoUpdate matrixAutoUpdate] for
|
|
|
- <em>every</em> instance of Object3D (or derived classes) created after the change has
|
|
|
- been made (already created Object3Ds will not be affected).
