摘要： A three dimensional adorner may be displayed with a corresponding three dimensional object when the object is created or inserted into a display and also at any subsequent time that the object is selected. Additionally, if any portions of the adorner are obscured, the adorner may be reoriented such that the obscured portions are made accessible. Distortion of the adorner in a perspective view may be reduced by removing the adorner from the perspective view, regenerating the adorner in an orthographic view, and then merging the orthographic view of the regenerated adorner with the perspective view of the corresponding object.

摘要翻译： 当对象被创建或插入到显示器中时，以及在对象被选择的任何后续时间时，可以将三维广告器与对应的三维对象一起显示。 另外，如果adorner的任何部分被遮蔽，则可以重新定向adorner以使遮蔽部分可访问。 通过从透视图中删除adorner，在正交视图中重新生成Adorner，然后将再生的adorner的正交视图与相应对象的透视图合并，可以减少透视图中的adorner的失真。

摘要： A system and method for rapid processing of scene-graph-based data and/or programs is disclosed. In one embodiment, the system may be configured to utilize render molecules to more efficiently render objects. A render molecule is an object that defines the rest of the attribute settings for the geometries it contains. The attribute settings can include settings such as materials settings, the composite transform from the root of the scene graph to the objects contained in the render molecule.

摘要： A system and method for performing visible object determination based upon a dual search of a cone hierarchy and a bounding (e.g. hull) hierarchy. Visualization software running on a host processor represents space with a hierarchy of cones constructed by recursive refinement, and represents a collection of objects with a hierarchy of bounding hulls. The visualization software searches the cone and hull hierarchies starting with the root cone and the root hull. Before exploring a given cone-hull pair, a cone-restricted minimum distance between the cone and the hull is measured and compared to the visibility distance value of the cone. Only when the former is smaller than the latter will the cone be searched against the hull.

摘要： A system and method for performing visible object determination based upon a dual search of a cone hierarchy and a bounding (e.g. hull) hierarchy. Visualization software running on a host processor represents space with a hierarchy of cones constructed by recursive refinement, and generates a hierarchy of bounding hulls from a given collection of objects by recursively grouping clusters of objects. Hull nodes in the hull hierarchy reflect cluster membership. Each hull node stores parameters which characterize a bounding hull for the corresponding cluster or object. The visualization software searches the cone and hull hierarchies starting with the root cone and the root hull. Each leaf-cone is assigned a visibility distance value which represents the distance to its closest known object. The visibility distance value of a non-leaf cone is set equal to the maximum of the visibility distance values for its subcone children. Before exploring a given cone-hull pair, a cone-restricted minimum distance between the cone and the hull is measured and compared to the visibility distance value of the cone. Only when the former is smaller than the latter will the cone be searched against the hull. Assuming the search condition is satisfied, subhulls of the given hull are again conditionally explored against the given cone (or its subcones) in ascending order of their cone-hull distances from the cone (or its subcones). When the recursive search of the two trees is completed, visible objects will have been assigned to each leaf-cone.

摘要翻译： 一种用于基于锥体层次和边界（例如船体）层次的双重搜索来执行可见物体确定的系统和方法。 在主处理器上运行的可视化软件表示具有通过递归细化构建的锥体层次结构的空间，并且通过递归地分组对象群集来生成来自给定对象集合的边界船体层级。 船体层次结构中的船体节点反映了群集成员资格。 每个船体节点存储表征相应群集或对象的边界船体的参数。 可视化软件从根锥和根外壳开始搜索锥体和船体层次结构。 每个叶锥被分配一个可见度距离值，其表示到其最接近的已知对象的距离。 将非叶锥的可视距离值设置为等于其子人孩子的可见度距离值的最大值。 在探索给定的锥体对之前，测量锥体和船体之间的锥形限制最小距离，并与锥体的可见度距离值进行比较。 只有当前者小于后者时，才能将锥体与船身对齐。 假设搜索条件满足，给定船体的子船体以锥体（或其子台）的锥体距离的升序再次有条件地针对给定锥体（或其子台）进行有针对性的探查。 当两棵树的递归搜索完成后，可见对象将被分配给每个叶锥。

摘要： An editing application may allow a user to change a literal property value of an object in a conventional manner. The functionality of the editing application may be expanded to allow a user to access non-literal values for property values, by allowing the user to define a calculation based on one or more sources. To indicate that an associated property value of an object is a non-literal value, a non-literal cue may be presented to the user, such as through the display of the object, the associated property indicator, and/or the associated property value. To reduce the learning curve of the expanded functionality, the user interface for literal values of a property may remain minimally impacted, while, alternative gestures associated with the object, property indicator, and/or property value may be used to allow access to the non-literal value controls or information.

摘要： A system and method for rapid processing of scene-graph-based data and/or programs is disclosed. In one embodiment, the system may be configured to utilize a scene graph directly. In another embodiment, the system may be configured to generate a parallel structure including a plurality of data structures and corresponding threads that manage the data originally received as part of the scene graph. The data structures and threads may be configured to convey information about state changes through the use of messaging. The system may include support for messaging between threads, messaging with time and/or event stamps, epochs to ensure consistency, and ancillary structures such as render-bins, geometry structures, and rendering environment structures.

摘要： A method of converting between color spaces where color components are cached when they are well-defined after color space conversion. When the components become undefined after conversion, the cached values are used instead of using an arbitrary default value. The resulting color editing system is “robust” in that it matches users' expectations, shielding them from Surprising glitches introduced by the user of the arbitrary values for undefined color components.
