Abstract: It is aimed to increase efficiency and simplification of a pixel circuit having a threshold voltage correcting function. A sampling transistor Tr1 is brought into conduction in response to a control signal supplied from a scan line WS and samples a video signal supplied from a signal line SL to a pixel capacitor Cs during a horizontal scanning period.

Abstract: A method for generating time-resolved 3D medical images of a subject by imparting temporal information from a time-series of 2D medical images into 3D images of the subject. Generally speaking, this is achieved by acquiring image data using a medical imaging system, generating a time-series of 2D images of a ROI from at least a portion of the acquired image data, reconstructing a 3D image substantially without temporal resolution from the acquired image data, and selectively combining the time series of 2D images with the 3D image. Selective combination typically involves registering frames of the time-series of 2D images with the 3D image, projecting pixel values from the 2D image frames “into” the 3D image, and weighting the 3D image with the projected pixel values for each frame of the time-series of 2D images.

Abstract: To provide a CAD-system projection method for a further improvement in user convenience by preventing unnecessary dimension lines from being added when a projection drawing is created from a three-dimensional model. A pre-projected projection drawing is used to set, as objects to be projected, a three-dimensional element of a component in an edit state and a scale line added to the three-dimensional line, the three-dimensional element being a projection source of a two-dimensional element in the projection drawing. Thus, a three-dimensional element that is not in the edit state, a dimension line therefore, and a three-dimensional element that is not a projection source of the two-dimensional element in the projection drawing, and a scale line for the three-dimensional line are not projected. Consequently, it is possible to obtain a projection drawing that includes necessary projection lines and a dimension line therefore.

Abstract: Systems and methods for providing smooth level of detail (“LOD”) transition for textures in a graphics applications are disclosed. The texture LOD of a first frame of imagery can be compared to a second texture LOD for a current frame. For areas where the second LOD is higher than the first LOD, an LOD fade from the first LOD to the second LOD can be performed to provide a smooth LOD transition. The LOD fade can be implemented by generating a blend between textures at the first LOD and the second LOD. In one aspect, the blend is generated based on an interpolant value calculated based on the difference between the first LOD and the second LOD. The interpolant value can be incremented in subsequent frames to achieve a desired fade rate for the transition. The fade rate can be variable such that the LOD transition time remains constant.

According to the invention, visual codes are assigned to the fitted function or to the data points of the point set piecewise or pointwise depending on the residual errors, and the fitted function is displayed graphically at an interface, wherein the fitted function is displayed piecewise or pointwise in the form of the assigned visual codes. The invention is preferably used for raster image spectroscopy with laser scanning microscopes.

Abstract: One embodiment of the present invention sets forth a technique for efficiently creating and accessing an A-Buffer that supports multi-sample compression techniques. The A-Buffer is organized in stacks of uniformly-sized tiles, wherein the tile size is selected to facilitate compression techniques. Each stack represents the samples included in a group of pixels. Each tile within a stack represents the set of sample data at a specific per-sample rendering order index that are associated with the group of pixels represented by the stack. Advantageously, each tile includes tile compression bits that enable the tile to maintain data using existing compression formats. As the A-Buffer is created, a corresponding stack compression buffer is also created. For each stack, the stack compression buffer includes a bit that indicates whether all of the tiles in the stack are similarly compressed and, consequently, whether the GPU may operate on the stack at an efficient per pixel granularity.

Abstract: A system and method of capturing, storing, editing and outputting multi-track motion data in a continuous stream on a computer with deterministic timing, where the length of the motion dataset is not limited by computer Random Access Memory. A hard real time periodic motion task takes in data streams from sensors or other computers, stores it in a shared memory area, and streams out the data to other computers so as to actuate motion. A shared memory area stores buffers and flags which indicate what data should be swapped to and from persistent storage. A soft real time periodic task transfers data pages between RAM and persistent storage based on requests from the motion task. Three data pages surround the active point in the motion dataset, four pages are reserved for copying whole blocks of data, and three pages are reserved for data editing. These ten active memory pages define a fixed memory footprint which can handle a deterministic data stream of effectively infinite length.

Abstract: Systems, methods, and apparatus for simulating natural media painting in a digital painting application (or painting simulation module) may provide user interface elements and methods that allow a user to load a brush with non-uniform paint colors by directly sampling the digital canvas. For example, a user may hover the brush over an area on the canvas having a non-uniform color distribution, and the application (or module) may sample the colors of the pixels under the brush, and load the brush with a collection of paint values reflecting the non-uniform distribution of colors in the sample.

Non-uniform paint loading may be applied to stamp-based brush models and/or bristle brush models.

Abstract: Most three dimensional geometric modeling programs employ a feature-based parametric modeling technique. A modification attempted by a user in a feature-based parametric modeling may provide a result different than that expected by the user, since most edits require a “roll back” of a history tree to the state wherein the geometry was originally created. Upon completing the edit, the tree rolls forward, taking into account the changes you have made. A problem arises when a parent feature is destroyed and now a child feature can no longer properly bind. The disclosed invention solves this problem by rolling back the tree to find the last successful bind made by the child, and then roll the model forward such that all downstream binding occurs with the successful bind in tact.

Abstract: A method and apparatus for rendering a computer generated image using a stencil buffer is described. The method divides an arbitrary closed polygonal contour into first and higher level primitives, where first level primitives correspond to contiguous vertices in the arbitrary closed polygonal contour and higher level primitives correspond to the end vertices of consecutive primitives of the immediately preceding primitive level. The method reduces the level of overdraw when rendering the arbitrary polygonal contour using a stencil buffer compared to other image space methods. A method of producing the primitives in an interleaved order, with second and higher level primitives being produced before the final first level primitives of the contour, is described which improves cache hit rate by reusing more vertices between primitives as they are produced.
