Systems and methods for generating a panorama image. Captured images are coarsely aligned, and then finely aligned based on a combination of constraint values. The panorama image is generated from the finely aligned images.

Method and system for image generation

System and method for rendering virtual objects onto an image.

Method and system for scene image modification

The method for virtual interaction with a three-dimensional indoor room includes: generating a virtual room model, generating a virtual room visual representation, providing the room data to a display device, receiving a virtual object selection, rendering an updated virtual room visual representation based on the virtual object, and providing the updated virtual room visual representation to the display device. The method can optionally include updating virtual room S. A system for virtual interaction with a three-dimensional indoor room includes: a backend platform and a front end application.

Virtual interaction with three-dimensional indoor room imagery

A method and system for generating a virtual representation of a physical scene, including receiving scene data corresponding to the physical scene, processing the scene data to determine scene components and scene priors corresponding to the scene components, generating, by a plurality of neural networks, dense geometric representations based at least in part on the scene priors, where each dense geometric representation corresponds to a scene component in the scene components, generating a virtual model of the physical scene based at least in part on the dense geometric representations, and generating a virtual representation of the physical scene based at least in part on the scene data, the virtual representation being aligned with the virtual model.

A method for determining a visual scene virtual representation and a highly accurate visual scene-aligned geometric representation for virtual interaction.

A system, method, and computer program product for rendering gaseous volumetric objects scenes using an alpha channel. In one described implementation, the method determines a distance between a user to boundaries of a gaseous volume and then stores the distance in an alpha channel to arrive at an alpha value. Then the alpha value can be used as a factor assist in blending scene colors with gaseous colors to render virtually realistic pixels for the gaseous object from the perspective of a user's view of the object. The resulting scenes can then be used to simulate patchy fog, clouds, or other gases of more or less constant density and color.

A method and apparatus for early occlusion culling are provided. For the method of the present invention, a host processor establishes a coarse Z-buffer. The coarse Z-buffer is divided into a series of tiles. Each tile has an associated depth value. The depth values are updated using information fed back from the Z-buffer. The host processor uses the depth values to selectively discard occluded objects before they are rendered.

A variable number of textures are blended together using a single texture as a mask. At least four textures are received. Masks are extracted from one of the received textures and used to blend together the remaining textures. In an embodiment, N masks are extracted from a single texture and used to blend N&plus;1 additional textures. In this embodiment, two of the N&plus;1 textures are initially blended together in accordance with one of the N masks to form an image. Another texture of the N&plus;1 textures is then blended with the image in accordance with another one of the N masks. This iterative blending process continues until all of the N&plus;1 textures have been blended together. In another embodiment, N textures are blended together by multiplying each of the N textures by one of the N masks and adding together the results of the N multiplications.

A method, system, and computer program product are provided for texture tiling with adjacent information. Adjacency information is supplied for one or more potential tiling directions. In one example, adjacency information is supplied for eight potential tiling directions radiating in eight different directions relative to an original texture image. In another example, adjacency information is supplied for three potential tiling directions. The present invention provides a solution that allows the specification of a texture image as a border to another for texture tiling purposes. This means that when texture addressing extends beyond the region within a texture map another texture image is addressed. During texture processing, in mapping a graphics primitive to adjacent border textures, two steps are carried out. The first step evaluates texture coordinate values to determine when texture coordinates are outside a range of a base texture image being texture mapped. The second step determines which adjacent border texture corresponds to the texture coordinates evaluated to be outside the base image. This determination is made using adjacency information which identifies the direction of the adjacent border texture relative to the base image.

Texture tiling with adjacency information

A method, system, and computer program product for filtering textures applied to a surface of a computer generated object permits an application program running on a computer system to significantly increase the graphics capabilities and performance of the computer. Rendering data for a pixel of the object is received from the application program, and a first and second set of texture coordinates is generated. Next, the first and second sets of texture coordinates are used to obtain a first and second texture sample from a texture image. The first and second texture samples are then blended together to produce a texture sample having a greater degree of filtering. This produced texture sample having a higher degree of filtering is stored in a frame buffer for subsequent display. The filtering process of the present invention can be performed either by conducting multiple passes through a graphics pipeline having a single texture unit or by conducting one pass through a graphics pipeline having multiple texture units. The filtering process of the present invention can also be performed by conducting multiple passes through a graphics pipeline having multiple texture units.

A first copy of an object is rendered using a texture sample selected from a texture image. This texture sample is selected from the texture image according to a first set of texture coordinates. The rendered object is stored in a frame buffer. Next, a second copy of the object is rendered using a second texture sample selected from the texture image. The second texture sample is selected from the texture image according to a second set of texture coordinates calculated in accordance with the first set of texture coordinates and one or more Jitter factors. The second set of calculated texture coordinates is displaced from the first set of texture coordinates along an axis of anisotropy. This second rendered copy of the object is then blended with the first rendered copy of the object to produce an object with anisotropic filtering. In embodiments of the invention, more than two copies of the object are rendered and blended together to form an object with anisotropic filtering.
