Abstract: During an analysis technique, a three-dimensional (3D) image of a portion of an individual is iteratively transformed to facilitate accurate determination of detailed multi-point annotation of an anatomical structure. In particular, for a given marker point, in response to receiving information specifying a two-dimensional (2D) plane having an angular position in the 3D image, the 3D image is translated and rotated from an initial position and orientation so that the 2D plane is presented in an orientation parallel to a reference 2D plane of a display. Then, after annotation information specifying the detailed annotation in the 2D plane of the given marker point is received, the 3D image is translated and rotated back to the initial position and orientation. These operations may be repeated for one or more other marker points.

Abstract: In various embodiments, a finite aperture omni-directional camera is modeled by aligning a finite aperture lens and focal point with the omni-directional part of the projection. For example, each point on an image plane maps to a direction in camera space. For a spherical projection, the lens can be orientated along this direction and the focal point is picked along this direction at focal distance from the lens. For a cylindrical projection, the lens can be oriented along the projected direction on the two dimensional (2D) xz-plane, as the projection is not omni-directional in the y direction. The focal point is picked along the (unprojected) direction so its projection on the xz-plane is at focal distance from the lens. The final outgoing ray can be constructed by sampling of point on this oriented lens and shooting a ray from there through the focal point.

Abstract: A method of processing primitives within a tiling unit of a graphics processing system is described. The method comprises determining whether a primitive falls within a tile based on positions of samples within each pixel. If it is determined that the primitive does fall within a tile based on the positions of samples within pixels in a tile, an association between the tile and the primitive is stored to indicate that the primitive is present in the tile. For example, an identifier for the primitive may be added to a control stream for the tile to indicate that the primitive is present in the tile. Various different methods are described to make the determination and these may be used separately or in any combination.

Abstract: Rendering systems that can use combinations of rasterization rendering processes and ray tracing rendering processes are disclosed. In some implementations, these systems perform a rasterization pass to identify visible surfaces of pixels in an image. Some implementations may begin shading processes for visible surfaces, before the geometry is entirely processed, in which rays are emitted. Rays can be culled at various points during processing, based on determining whether the surface from which the ray was emitted is still visible. Rendering systems may implement rendering effects as disclosed.

Abstract: Techniques of simplifying triangular meshes involve performing machine learning on triangle mesh data to produce simplified triangle mesh data representing a simplified triangle mesh having a specified number of triangles. Along these lines, a computer obtains triangular mesh data representing a triangular mesh that approximates an object. For example, a triangular mesh that provides a very good approximation of a human head may have tens or hundreds of thousands of triangular faces and vertices. The computer then inputs this triangular mesh data and a specified number of triangular faces into a machine learning application. The specified number of triangular faces is much less than the number of faces in the triangular mesh data input into the machine learning application.
