Abstract: A method and system provide for automating drawing. A drawing of two or more entities is obtained and a resolution is determined. Based on the resolution, the drawing is quantized into a cell map. The cell map is a collection of multiple cells stored in a contiguous memory. Each of the multiple cells is quantized geometry data for and provides a smallest tangible unit of information about a corresponding entity. Each of the multiple cells is a number that represents domain specific information about the corresponding entity. The quantizing rounds off of values beyond a specified threshold to a resolution tolerance of the resolution. The cell map is utilized to automate modifications to the drawing.

Abstract: A method and system provide the ability to determine a hydrant fire flow. Inputs are obtained A critical element is identified. Based on a physical-based heuristic, a new hydrant fire flow guess is determined. The search direction is evaluated and used to maintain/override (using a heuristic method) the fire flow guess. The new guess is assigned as a hydrant demand. Network pressure and flow values are updated. The constraints are evaluated. The guess is reduced if at least one constraint has been violated and increased of all constraints have been satisfied. The new guess is evaluated for convergence and if not converged, the process repeats.

Abstract: A method and system provide for extracting an isosurface. A set of three-dimensional (3D) asymmetric sampling grids are created based on a sampling resolution and a region of interest. The set of grids cover a 3D scalar field and are tiles made up of tetrahedrons. The 3D scalar field is evaluated based on the set of 3D asymmetric sampling grids to generate a value for each tile, convert the values to cells, and assign an index to each cell. For each cell, the index is utilized to identify, in a lookup table, an enumerated tetrahedron. For each identified enumerated tetrahedron that contains an isosurface crossing, an isosurface connection is estimated between new points of edges of the identified tetrahedron. A mesh is created to connect the new points and utilized as the extracted isosurface.

Abstract: Techniques are disclosed for storing and accessing data in an information model. In some embodiments, data is stored in the information model using assets, components, and relationships, or using any other suitable transformation of the data. Each asset is a container for components. Each component stores data according to a schema that defines the organization of data in the component. Assets and components can be related to other assets and/or other components. A file can be imported into the information model by extracting data from the file, creating assets and components in the information model based on the extracted data, and wiring together the created assets and components. In addition or alternatively, an application can invoke an API to write data to the information model. An application can also invoke the API to query the information model, such as to read data from the information model.

Abstract: A voxel-based design approach enables the creating and modifying of a design model comprising a 3D grid of discrete voxels that is represented by a voxel data structure. The voxel data structure comprises voxel-level entries, each entry corresponding to a voxel based on the 3D location within the 3D grid. The voxel data structure includes a design-level entry for storing design-level performance metrics. The system updates the voxel data structure to reflect user modifications to the design model and renders a visualization of the updated design model. The system displays a per-voxel heat map for the design model for a selected performance metric based on the voxel data structure. The design system displays multiple optimized design solutions based on corresponding optimized voxel data structures. The system generates the multiple optimized design solutions based on a voxel-based optimization technique. The system also performs a voxel-based recommendation visualization technique.

Abstract: A method and system provide the ability to build a game world. A story is obtained that provides a textual narrative of a sequence of events. Plot facilities and a set of constraints are extracted from the story. Each of the plot facilities is a conceptual location where an event happens in the story. Each constraint defines a spatial relation between plot facilities. A map is generated based on the set of constraints by: generating a terrain of two dimensional (2D) polygons that is each associated with a biome type, and assigning each plot facility to a point on the terrain. The assigning complies with a maximum number of constraints and utilizes reinforcement learning (RL) to optimize positions of the points.

Abstract: A method and system provide the ability to utilize three-dimensional (3D) models to perform a predictive task. Multiple 3D models, consisting of non-Euclidean data, are obtained. Each 3D model is translated into a relational graph with nodes and edges. Each relational graph is processed using a graph neural network (GNN) that computes a node representation per node. The node representations are aggregated into a structural representation of the 3D model. Multiple different views of the 3D model are captured and passed through a convolutional neural network (CNN) to compute a view representation of each view. The view representations are aggregated into a single visual representation. The GNN and CNN are trained using a multiview contrastive training objective to maximize agreement between the structural representation and the single visual representation to form final learned representations. The final learned representation is utilized to perform the predictive task.

Abstract: Techniques are disclosed for determining users, tasks, and levels of expertise in fabrication environments. Sensors may be placed in a fabrication environment, instrumented in tools, and/or worn on users. Given labeled features extracted from sensor data, machine learning techniques are used to train models to recognize users, tasks, and levels of expertise. The trained models may then be deployed to determine the users, tasks, and levels of expertise in a fabrication environment based on features extracted from new sensor data. In turn, actions such as displaying guidance or instructional materials, or locking a user out of using certain tools or parts of the fabrication environment, may be taken.

Abstract: Design process that performs geometry synthesis on a 3D model of a product based on a design problem statement and manufacturing constraints associated with a manufacturing machine intended to manufacture the product. The manufacturing constraints may include dimensions for a tool bit, dimensions for a tool head, a set of machining directions of the manufacturing machine, or any combination thereof. For a 5-axis manufacturing machine, the set of machining directions may be determined by a “NormalSearch” algorithm and/or a “HeatSearch” algorithm. The geometry synthesis produces a design solution comprising a final 3D model of the product, whereby each point on the boundary of the final 3D model is determined to be accessible by a tool bit and/or tool head in at least one machining direction of the manufacturing machine. Thus, the design solution for the product is more easily and directly manufacturable by the manufacturing machine.

Abstract: A method and system control a water distribution network. A database is maintained of prior states based on a residential water demand, a tank level, and an energy tariff. A current state of the water distribution network is determined. Rewards are determined and include a tank level constraint, an energy cost, and a toggle count. A query based model is used to determine a set of control points used to control a first prior state. An RL agent is trained based on the prior states and rewards. The RL agent determines a control setpoint (that changes the pump speed) that maintains the tank level, minimizes the energy cost, and complies with the toggle count. The RL agent determines time slots and selects one of the time slots. Hybrid setpoints are generated to control the water distribution network within the selected time slot.
