    摘要: A lighting model specified in light space may be transformed to a 3D scene, which may include numerous lights. When the lighting model is transformed to the 3D scene and is uniformly scaled or near-uniformly scaled, intensity or brightness of light at sample points, corresponding to points in the 3D scene, may be adjusted proportionately for a light source using a value based, at least partly, on a transform matrix. When the lighting model in the light space is scaled to non-uniformly stretch a lit area, the sample points may be transformed to the light space, using an inverse of a transform matrix. Distances from the light source to the transformed sample points in the light space may be used to determine attenuation and range with respect to the light source.

    摘要: Various technologies and techniques are disclosed that improve the process of working with 3D rotations. Rotations are treated as a separate abstract entity from general transforms. By having rotations separate from general transforms, the user can perform the various operations on any “rotation” regardless of its encoding. An abstract 3D transform class is provided that represents a transform that can be applied to 3D a mesh or scene node, and an abstract 3D rotation class is provided which is exposed separately from other general transforms. A concrete implementation of the 3D transform class uses a 3D rotation class to apply a rotation to a 3D mesh or scene node. One or more concrete implementations of the 3D rotation class are provided which represent a separate rotation encoding.

    摘要: A computing system translates two-dimensional (2D) graphical input by a user who is selecting one or more 2D images in a three-dimensional (3D) scene of 3D models created by model 3D objects. The computing system comprises a viewport module, a retrieve module, set ray module and, a hit detection module. The viewport module defines 2D boundaries of the 3D scene and a view point location in 3D space for viewing the 3D scene. The retrieve module retrievies a selection point location in 2D space for the 2D graphical input. The set ray module sets a pick ray in 3D space based on the view point location and the selection point location. The hit detection module detects a hit by the pick ray on a 3D model in the 3D scene. In this computing system there is a method of processing a hierarchy of computer program visual objects for detecting a hit by 2D input on 2D and 3D images displayed by a computing system. The method begins by traversing branches of a first tree hierarchy of visual objects to leaf objects. Next the method detects whether the next unprocessed leaf object is a visual 2D object with 2D geometry or a model 3D object with 3D geometry. Lastly the method calls a 2D process to detect a hit on the 2D geometry of a visual object if a visual 2D object is detected and calls the 3D process to detect a hit on the 3D geometry of a visual object if a model 3D object is detected.

    摘要: Compositions and methods of increasing the bioavailability of catechins are presented. Compositions for increasing the bioavailability of catechins include compositions where the catechin is added to a solution of ethanol and water; compositions where the catechin is encapsulated within a nanoparticle; and compositions in which a nanoparticle complex is formed between the catechin and the nanoparticle. Each of these compositions was shown to increase bioavailability of EGCG and is useful in treating diseases such as Alzheimer's and HIV-associated dementia.

    摘要: The present invention relates to a geographic information system having editable maps. In an embodiment, a system provides editable maps. The system includes an edit layer dataset that stores geocoded data. At least a portion of the edit layer dataset is edited by a user. The system also includes a base layer dataset that includes trusted geocoded data and a moderation module that receives a change in the edit layer dataset. The moderation module determines whether the change is reliable and promotes the change in the edit layer dataset to the base layer dataset if the change is reliable.
