摘要： A physical process is simulated by storing in a memory state vectors for voxels and a representation of at least one surface. The state vectors include entries that correspond to particular momentum states of set of possible momentum states at a voxel. Interaction operations are performed on the state vectors to model interactions between elements of different momentum states. In addition, surface interaction operations are performed on the representation of the surface. The surface interaction operations model interactions between the surface and elements of at least one voxel near the surface. The elements have a tangential momentum relative to the surface, and the surface interaction operations retain at least a portion of the tangential momentum of the elements. The portion of tangential momentum retained corresponds to a friction parameter. The friction parameter is varied based on changes in pressure near the surface. Finally, move operations are performed on the state vectors to reflect movement of elements to new voxels.

摘要翻译： 通过在存储器状态中存储体素向量和至少一个表面的表示来模拟物理过程。 状态向量包括对应于在体素处的可能动量状态集合的特定动量状态的条目。 对状态向量执行交互操作，以模拟不同动量状态的元素之间的相互作用。 此外，对表面的表示执行表面相互作用操作。 表面相互作用模型在表面附近的至少一个体素的表面和元素之间的相互作用。 元件相对于表面具有切向动量，并且表面相互作用操作保持元件的切向动量的至少一部分。 保留的切向动量部分对应于摩擦参数。 摩擦参数根据表面附近的压力变化而变化。 最后，对状态向量执行移动操作，以反映元素向新体素的移动。
