Abstract: An enlarged computer graphic image of borehole data is displayed on a concave three-dimensional surface, preferably a semi-cylindrical shape. Thus providing an enlarged image of a borehole surface where the data is spatially correct in three-dimensions, and which increases the ease with which interpreters can locate geological features such as surfaces, faults, and fractures.

Abstract: A video projection system employing a concave video screen which provides for enhanced depth cueing. A method of designing a variety of shapes of video screen surfaces by varying certain parameters of a common master equation. Video screen surface shapes providing optimum viewing for specific applications.

Abstract: A method for recognizing and comparing features of attribute data expressed in a 3D data survey involves: extracting, mapping, color coding and displaying 3D data for at least one attribute. Preferably, the data is based on tomographic paths. The tomographic paths are defined within a subvolume of instantaneous attribute data having the shape of a sphere. This is accomplished by extracting the subvolume of attribute data having a desired shape, defining multiple tomographic paths extending from a point within the subvolume to its bounding surface, combining instantaneous attribute values encountered along each of the tomographic paths to determine multiple aggregate values, mapping the thus determined aggregate attribute values on the surface of the sphere using a color code, and displaying the color coded sphere. The attribute maps are correlated with preexisting geological or stratographic templates to identify features.

Abstract: An enlarged computer graphic image of seismic data is displayed on a concave three-dimensional surface having a shape corresponding to the shape of selected data extracted from a three-dimensional seismic volume. Thus providing an enlarged image of a seismic surface where the data is spatially correct in three-dimensions, and which increases the ease with which interpreters can locate geological features such as horizons, faults, and channels. An auxiliary paddle screen is provided to display an interactive video image for exploring the volume within the hybrid screen.

Abstract: An improved method for recognizing and comparing features of attribute data expressed in a 3D data survey involves: extracting, mapping, color coding and displaying 3D data for at least one attribute. Preferably, the data is based on tomographic paths. The tomographic paths are defined within a subvolume of instantaneous attribute data having the shape of a sphere or other solid figure. This is accomplished by extracting the subvolume of attribute data having a desired shape, defining multiple tomographic paths extending from a point within the subvolume to its bounding surface, combining instantaneous attribute values encountered along each of the tomographic paths to determine multiple aggregate values, mapping the thus determined aggregate attribute values on the surface of the sphere using a color code, and displaying the color coded sphere.

Abstract: A desktop based projector screen having an inner concave display surface upon which a video image or a series of images is projected with a sense of realism comparable with natural viewing of three-dimensional physical reality. The viewing surface combines three concave sections which are derived from solid figures including a dome, cylinder and a plane.
