A method for volume ray casting is provided. For each pixel of a 2D image placed in a view plane a ray of sight is projected through a volume determined by a plurality of voxels of a volumetric dataset indicative of an object. A plurality of sampling points is determined along each ray of sight such that a distance between two consecutive sampling points is larger at a larger distance to the view plane. At each sampling point a color value and a transparency value is determined in dependence upon voxels in proximity of the sampling point and a lighting calculation, wherein for the lighting calculation a first lighting model and a second lighting model are used in dependence upon a distance of the sampling point to the view plane. For each ray of sight a final color value is determined by compositing along the ray the color values and the transparency values. The final color value of each ray corresponds to a pixel value of the 2D image. The color and the transparency value of a sampling point are composited with the color and transparency value of a previous sampling point before determining the color and transparency value of a following sampling point. The compositing is stopped when the composited transparency value is within a predetermined range less than a value indicative of opacity.

Systems and methods for providing remote access to an application program. A server remote access program may cooperate with display data interception application to provide display data to a client computing device. The client computing device may connect to the application at a Uniform Resourced Locator (URL) using a client remote access application to receive the display data. The client remote access application may provide user inputs, received at the client computing device, to the application to affect the state of the application.

Remote access to an application program

A method and system for providing remote access to data for display on a client computer via a computer network is provided. A first and second server computer connected to a computer network execute a first and second server remote access program, respectively, for communicating with an associated first and second application program. The client computer, which is also connected to the computer network, executes a client remote access program for simultaneously communicating with the first and second server remote access programs via a first and second communication link. The first and second server remote access programs determine first and second presentation data indicative of an application state of the first and second application programs. The client remote access program receives the first and the second presentation data and determines display data in dependence thereupon for substantially simultaneously displaying the first and the second presentation data.

Method and system for providing remote access to data for display on a mobile device

Methods and apparatuses for enabling remote access to an application program via a computer network provided. Logical elements of the application program may be determined, from which a state model of the application program may be developed. A remote access program updates the state model in accordance with user input data received from a user interface program, generates control data in accordance with the updated state model and provides the same to the application program. The state model may be updated in accordance with application data received from the application program, application representation data in accordance with the updated state model are generated and provided to the user interface program for display at, e.g., a remote client computing device. The application program may be a legacy mainframe application to which remote access is provided without the need to modify the source code of the mainframe application.

Method and system for providing a state model of an application program

An example method for providing simultaneous interaction with a plurality of application programs is described herein. The method includes providing a remote access framework for enabling a client to remotely access the application programs over a network, receiving a communication from the client through the remote access framework, and maintaining a state model within the remote access framework. The state model includes respective application states of the application programs. The method also includes, using the state model, linking interactive functionalities of the application programs, and generating display data indicative of a single user interface including the plurality of application programs. The method further includes communicating the display data to the client through the remote access framework.

Method and system for enabling interaction with a plurality of applications using a single user interface

Systems and method for providing remote access to service applications created within an application framework. For each of the controls in the application framework, a wrapper is provided to enable remote-access to the control. An integration component includes proxies that communicate to each the rapper, a proxy manager that communicates to the service application, and a state manager that registers views and event handlers to communicate application state information. A remote access server application receives a connection from a client remote access application executing on the client device, and state information is communicated between the service application and the client remote access application to provide a view of the service application at the client device.

Generalized proxy architecture to provide remote access to an application framework

Systems and methods for providing remote access to an application program. A server remote access program may cooperate with a screen scraping application to provide screen data to a client computing device. The display associated with the application program may be resized or cropped by a server for display on the client computing device. The client may connect to the server using a client remote access program that receives inputs from a user interface program.

Non-invasive remote access to an application program

A method for remotely calibrating display of image data is provided. Using a processor of the client computer display data are determined. The display data are indicative of a luminance dynamic range of the display and of an ambient lighting environment of the display. The display data are then transmitted to a server computer. Using a processor of the server computer display adjustment data are determined in dependence upon the display data. The display adjustment data are then transmitted to the client computer. Alternatively, image data for displaying on the display are received. Adjusted image data are then determined in dependence upon the received image data and the display adjustment data and transmitted to the client computer.

Method and system for remotely calibrating display of image data

A method and system for accessing a data file is provided. At a server computer a request for accessing a data file of a plurality of data files stored in a database is received. The server computer is connected to the database via a first communication link and a second communication link. Metadata associated with the data file in the database are accessed via the first communication link using a first query protocol. In dependence upon the metadata the data file is located in the database. At least a portion of data stored in the data file is then accessed in the database via the second communication link using a second query protocol.

Data communication in a picture archiving and communications system network

The present invention relates to a method and system for processing multi-dimensional signal data to determine frequency dependent features therefrom. The multi-dimensional signal data are transformed into space-frequency or time-space-frequency domain, providing second signal data. At predetermined locations of at least a portion of the one of space and time-space of the second signal data a dominant feature corresponding to a largest value of the second signal data is determined. This is followed by the determination of a wave-vector corresponding to the dominant feature at each of the predetermined locations. Finally, a dip map, a frequency map, and an amplitude map are generated using the wave-vectors. The method and system for processing multi-dimensional signal data to determine frequency dependent features therefrom according to the present invention provide a powerful tool for improved and more detailed evaluation of seismic data using dip, frequency, and amplitude maps, resulting in substantially more accurate geophysical surveys.
