Abstract: Embodiments of the present invention are directed towards increasing texture filtering performance for texel components represented by more than 8 bits. As the number of bits per component increases, the number of texels that are processed each clock cycle decreases since more bits need to be processed to produce each filtered result. A filtered result may be accumulated over two or more iterations, with each iteration producing a portion of the filtered result. When only a portion of the components for each texel are used, the unused texel components are not processed. Elimination of unnecessary texel processing for unused texel components may improve texture filtering performance.

The method may include the following steps: estimating, for each vertex of at least a portion of a three dimensional (3D) mesh representing a model, projection parameters associated with a virtual camera that is unique for each vertex; mapping pixels from a two dimensional (2D) image to the vertices, such that each mapping of a pixel is based on the estimated respective virtual camera parameters; and texturing the portion of the mesh with corresponding mapped pixels wherein vertices on the textured portion are selected such that they are visible from a specified viewpoint associated with the 3D mesh.

Abstract: Surfaces without a global surface coordinate system are divided into surface regions having local surface coordinate systems to enable the caching of surface attribute values. A surface attribute value for a surface region may include contributions from two or more adjacent surfaces. Sample points may be arranged at the corners, rather than centers, of surface regions and include prefiltered values based on two or more surfaces. A renderer may sample the surface attribute function using these prefiltered values without accessing any adjacent surfaces, even if the renderer's filter crosses a surface boundary. A multiresolution cache stores surface attribute values at different resolution levels for surface regions of one or more surfaces, which may be discontiguous. Two or more resolution levels may have the same number of sample points but have values based on filters with different areas and spatial frequency limits. Resolution levels may be selected based on geodesic distance on a surface.

Abstract: A procedural texture relates texel coordinates to color values through an arbitrary function, herein called a texel shader. The procedural texture is defined by a dimension, size, texel format and the texel shader. Texel coordinates are an input to the texel shader, which generates a color value for those texel coordinates. A renderer can be implemented either in hardware, such as part of a graphics processor, or in software as a computer program executed by a processor. The renderer samples from the procedural texture in response to texel coordinates, and evaluates the texel shader on demand. Filtering also can be applied automatically to results. The results of the texel shader invocations are stored in a texture cache to take advantage of spatial and temporal locality. Results are shared among threads, processes and the like through the texture cache.

Abstract: An image for a virtual view of a scene is generated based on a set of texture images and a corresponding set of depth images acquired of the scene. A set of candidate depths associated with each pixel of a selected image is determined. For each candidate depth, a cost that estimates a synthesis quality of the virtual image is determined. The candidate depth with a least cost is selected to produce an optimal depth for the pixel. Then, the virtual image is synthesized based on the optimal depth of each pixel and the texture images. The method also applies first and second depth enhancement before, and during view synthesis to correct errors or suppress noise due to the estimation or acquisition of the dense depth images and sparse depth features.

Users input strokes and other image elements using an input device that specifies a 2D view of the element, and the system provides the 3D position of the element based on rules and processes, some of which allow for user input of high level parameters, thereby allowing for intuitive and quick entry of 3D elements, and a 3D scalar field.

The canvas need not be tied to any particular object already in a scene, but the canvas can be dependent on, or a function of, another object. An implicit canvas can be defined by the 3D scalar field.

Abstract: Two-dimensional (2D) animation may be generated from a three-dimensional (3D) mesh by a machine or device that flattens, textures, and modifies the 3D mesh, which results in distorting the texture of the 3D mesh. The machine or device is configured to access and flatten a 3D mesh of 3D vertices. At least some of the 3D vertices of the flattened 3D mesh are texture mapped with a 2D image.

Accordingly, 2D animation may be generated by distorting the 2D image that is mapped onto at least part of the 3D mesh.

Abstract: A system and method for rendering text data in web applications is provided that eliminates redundant processing. Constant resources are pre-computed and work is offloaded from the central processing unit to the graphics processing unit. This is generally accomplished by pre-computing before any rendering. A generic index vertex buffer object is created, and for each font, a glyph texture object and glyph position texture object are created. A frame including text is then rendered in which a glyph string texture object is created. For each character, a glyph index-to-texture and glyph offset to-texture is appended. A glyph texture, glyph position texture and glyph string texture are then bound, and the generic index vertex buffer object using a custom vertex shader is rendered.

Abstract: Systems and methods for reducing bit rates by replacing original texture in a video sequence with synthesized texture. Reducing the bit rate of the video sequence begins by identifying and removing selected texture from frames in a video sequence. The removed texture is analyzed to generate texture parameters. New texture is synthesized using the texture parameters in combination with a set of constraints. Then, the newly synthesized texture is mapped back into the frames of the video sequence from which the original texture was removed. The resulting frames are then encoded. The bit rate of the video sequence with the synthesized texture is less than the bit rate of the video sequence with the original texture. Also, the ability of a decoder to decode the new video sequence is not compromised because no assumptions are made about the texture synthesis capabilities of the decoder.

Abstract: There are both flat and sloped ground surfaces on which the game characters traverse. In areas where a sloped surface changes angle (i.e. where a sloped surface connects to a flat surface), a transitional method has been created to make the adjoining textures on the top surface area of the ground blend together seamlessly. A unique texture is used for this purpose. This texture uses the same material as the flat “ground trim” texture seen on the top of every surface. The texture has a diagonally drawn alpha mask that blends from completely transparent to completely opaque from the bottom right corner of the texture to the top left corner. When this texture is drawn at the ends of each sloped surface where they change angle, the combination of the color channels and the alpha mask line up with adjoining textures to blend them together and create a seamless visual transition.

The one or more computing devices provide the at least partially blurred rendering and subsequently provide for display a completely loaded version of the image.

A DIBR unit 17 applies pixel shifting to each background image constructing the joint background image and also conducts boundary processing relative to the pixel shifting. The joint background image is composed of one or more background images stitched together along their edges on a three-dimensional model.

The amount of shift applied to each pixel is determined based on the depth value of a corresponding pixel of a depth image. The boundary processing is to extract pixels shifted out of the display region of a given background image as a result of pixel shifting and add the extracted pixels to an edge of another background image adjacent to the given background image in the row direction.
