Filed:

Mar 15, 2006

Appl. No.:

11/376050

Inventors:

Alexander Stevenson - Bellevue WA, US
Daniel N. Wood - Seattle WA, US
Daniel R. Lehenbauer - Redmond WA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06T 15/40
G06T 15/30

US Classification:

345422, 345421

Abstract:

Various technologies and techniques are disclosed that improve the automatic generation of near and far clipping planes for a 3D scene. The viewing frustum is intersected with the scene to determine the range of depth that a particular scene occupies in the viewing frustum. The ratio of the near clipping plane to far clipping plane is adjusted as appropriate to ensure a desired minimum level of Z-buffer precision is achieved. The clipping planes are set sufficiently far outside of the object bounds to prevent triangles which are parallel to the clip planes from being accidentally clipped. An API is provided to allow other programs to retrieve the near and far clipping plane values with the desired minimum Z-buffer precision for a particular scene without having to interact with the Z-buffer.

International Classification:

G06T 15/50

US Classification:

345426, 345419

Abstract:

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.

International Classification:

G09G 5/00

US Classification:

345649000

Abstract:

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.

International Classification:

G09G 5/36

US Classification:

345545

Abstract:

A technique for generating content for a stereo 3D display buffer having both stereo 3D graphic objects and non-stereo 3D graphic objects that may be utilized to render stereo 3D content onto one or more windows of a display. The technique incorporates content from stereo 3D application frame buffers into a composition tree that represents the graphic objects in each window displayed on a computing device. At each refresh cycle, the composition tree is traversed to generate content for a stereo 3D display buffer that is then used to draw one or more windows onto a display.

International Classification:

G06T 1/60

US Classification:

345530

Abstract:

Buffer display techniques are described. In one or more implementations, at least part of an off-screen buffer is rasterized by an application to generate an item for display by the computing device. One or more communications are formed that describe the part of the off-screen buffer which contains the item that is to be copied to update an onscreen buffer.

US Classification:

719328, 345582

Abstract:

Atlasing and virtual surface techniques are described. In one or more implementations, virtual surface functionality is exposed by an operating system for access by one or more applications of the computing device. A virtual surface is created in response to a request from the one or more applications to be used to render visuals for display by a display device. The virtual surface is allocated in memory of the computing device by the exposed virtual surface functionality to have an area that is larger than an area to be used to display the visuals from the one or more applications.
