Abstract: Techniques for a texture modification feature are described herein. First data identifying a position and a distance of an actor in an environment from a view point is obtained. The actor may correspond to a mesh comprised of a plurality of triangles. Second data identifying a location, an angle, and size for each triangle of the plurality of triangles with respect to a spectrum of pre-defined viewpoints is obtained. A value for each triangle may be determined based on the first data and the second data. The value may represent a level of detail to optimize viewing of each triangle of the actor from a corresponding viewpoint of the spectrum of pre-defined viewpoints. One or more areas of a texture that corresponds to the mesh may be modified prior to applying the texture to the mesh based on the associated values for triangles of the mesh.

Abstract: High quality image rendering can be achieved in part by using inverse transform sampling to direct sampling toward regions of greater importance, such as regions with higher brightness values, to reduce noise and improve convergence. Inverse transform sampling can be achieved more efficiently by reformulating as a ray-tracing problem, using tree traversal units that can be accelerated. A geometric mesh can be generated based on a set of cumulative distribution functions (CDFs) for various rows and columns of pixels in a texture, and individual rays can be traced against this mesh, with those rays having a higher probability of intersection at a point with greater importance, such as a higher brightness value. A probability distribution function to be used for importance sampling can be derived by analyzing partial derivatives of the CDF geometry at the intersection location.

Abstract: In one or more embodiments, techniques are provided for modeling overhead line structures of electric railways that utilize a flexible, reusable structure template to automatically generate a 3D model of the overhead line structure. Each structure template includes a set of points that represent joints of the overhead line structure and components that represent elements of the overhead line structure. A feature definition of each joint and component includes properties, constraints and cell mappings. By mapping key points of reference lines for an overhead line structure to key points in an applicable structure templet for the overhead line structure, and applying the constraints and, in some cases the cell mappings, a 3D model of the overhead line structure is automatically generated. The 3D model may be a “low detail” stick representation for fast modeling, or, using the cell mappings, a “high detail” cell-based representation for very realistic modeling.

Abstract: An interface system generates interfaces for visualizing human-machine interactions including piping systems. The interface system receives, as input, parameters describing a first pipe data object and a second pipe data object. The pipe data objects can be diagrams representing physical piping in an industrial system. Using the parameters of the first and second pipe data objects, the system determines whether images of the pipes in the interface will overlap. When the system renders vector graphic images of the first pipe data object and the second pipe data object, the second pipe data object is rendered with markings that provide a visual indication that the two pipes overlap and are not connected. The interface system further enables a user to edit the piping diagram to combine the first and second pipe data objects into a single combined pipe data object and updates the rendered images for display.

Abstract: Improved texturing processes utilizing smart materials are provided to increase developer productivity when texturing objects within multi-dimensional environments, and particularly, 3D environments. A developer may generate an object, select a smart material to apply, and manipulate the dimensions of the object to cause an aspect ratio of at least one surface having a material applied to change without altering an aspect ratio of a texture tile of the material as rendered on the surface of the object. Texturing of object surfaces from a selected smart material is determined in a shared material space based on a mapping of object vertices that maintain original material qualities (e.g., a defined aspect ratio of the texture) and mitigate discontinuities in a material applied to adjacent surfaces, including those of different objects and when those objects are repositioned.
