Designing a modeled volume represented by dexels

摘要

It is provided a computer-implemented method for designing a modeled volume. The method comprises providing a sculpting process on the modeled volume, initial lines, and an initial set of dexels that represents the modeled volume after going through the sculpting process and that is based on the initial lines; then providing new lines by refining the initial lines; and determining a new set of dexels that represents the modeled volume after going through the sculpting process and that is based on the new lines, wherein determining the new set of dexels comprises determining sets of at least one segment representing the intersection between each new line and the modeled volume before going through the sculpting process and then applying the sculpting process on the determined sets of at least one segment. The method improves designing a modeled volume represented by a set of dexels.

1. A computer-implemented method for designing a modeled volume, wherein the method comprises:
with respect to a subject modeled volume, providing: (i) a sculpting process as a series of sculpting operations, (ii) initial lines, and (iii) an initial set of dexels, wherein the initial set represents the modeled volume after undergoing the sculpting process and is based on the initial lines, each dexel of the initial set comprising a set of segments representing an intersection between a respective one of the initial lines and the modeled volume, wherein the intersections of different initial lines are represented by respective different sets of segments, and wherein dexels of the initial set of dexels are associated with sculpting operations of the series that impact the dexels; providing new lines by refining the initial lines, wherein refining the initial lines comprises at least one of (i) increasing the density of the initial lines and (ii) discarding part of the initial lines; and determining a new set of dexels that represents the modeled volume after undergoing the sculpting process and is based on the new lines, wherein determining the new set of dexels comprises: (i) determining sets of segments, each set of the determined sets of segments representing an intersection between a different new line of the new lines and the modeled volume before undergoing the sculpting process, wherein the sets of segments are determined by retrieving history of the modeled volume and (ii) applying the sculpting process on the determined sets of segments using the series of sculpting operations associated with dexels of the initial set, wherein the associated dexels correspond to lines of the initial lines that are kept as part of the new lines.
