摘要： A system for controlling symmetry relationships in a three-dimensional (3-D) model is disclosed. The system includes a processor and a memory in communication with the processor. The memory is configured to store processor-executable instructions to identify a prototype object defined within the 3-D model, detect a symmetry object associated on the identified prototype object such that the symmetry object relates to the prototype object based on a differentiation function, quantify a plurality of model parameters associated with the symmetry object such that the plurality of model parameters defines the differentiation function, and couple the prototype object and the symmetry object based such that an update to one of the objects propagates to other object.

摘要： For efficient smooth particle hydrodynamics using more particle information, virtual particles are created. Each virtual particle represents an averaging of properties for the fluid particles in a cell. For density, force, or other calculations for a given fluid particle, the interaction between the particles within a cell are calculated. For calculating the influence of particles outside the cell on the particle in the cell, the virtual particles from the neighboring cells are used. The interaction with these aggregate particles reduces the number of calculations while still including the influence from particles of other cells.

摘要： A three-dimensional model is determined from a two-dimensional sketch. Rather than or in addition to modification of 3D constraints to reduce gaps in the 3D model, 2D constraints are modified. The geometry of the 2D sketch is altered in the view plane (x, y) or 2D input instead of maintaining the geometry of the 2D sketch and only modifying in the view direction (z). Gaps may be reduced through alteration of the 2D geometry.

摘要： Boundary handling is performed in particle-based simulation. Slab cut ball processing defines the boundary volumes for interaction with particles in particle-based simulation. The slab cut balls are used for collision detection of a solid object with particles. The solid object may be divided into a plurality of independent slab cut balls for efficient collision detection without a bounding volume hierarchy. The division of the solid object may be handled in repeating binary division operations. Processing speed may be further increased by determining the orientation of each slab cut ball based on the enclosed parts of the boundary rather than testing multiple possible orientations.
