Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than those herein described, and those skilled in the art will readily appreciate that the present application may be similarly embodied without departing from the spirit or essential characteristics thereof, and therefore the present application is not limited to the specific embodiments disclosed below.

The terminology used in the one or more embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the one or more embodiments of the application. As used in one or more embodiments of the application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used in one or more embodiments of the present application refers to and encompasses any or all possible combinations of one or more of the associated listed items.

It should be understood that, although the terms first, second, etc. may be used in one or more embodiments of the application to describe various information, these information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, a first may also be referred to as a second, and similarly, a second may also be referred to as a first, without departing from the scope of one or more embodiments of the application. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.

First, terms related to one or more embodiments of the present application will be explained.

Boundary representation: in computer aided design, the boundary representation is a method of preserving information required for how to build a model from its geometry, especially euler topology boundaries, which is often abbreviated as BREP (english full name Boundary Representation). An important feature of the boundary representation is that the information describing the shape includes both geometric information (english name Geometry) and topological information (english name Topology). Topology information describes the connection of vertices, edges, faces on a body, which forms a "skeleton" that the object boundary represents. The geometric information of the body can be seen as muscles attached to a "skeleton". For example, a surface of a body is located on a curved surface, and the data defining this surface equation is geometric information. In addition, the shape of the side, the position of the vertex in three-dimensional space (coordinates of the point), and the like are geometric information, which generally describes the size, dimension, position, shape, and the like of the feature. In the boundary representation, the boundary representation records the geometric information of all geometric elements constituting the body and the topological relation of the interconnection thereof in detail according to the hierarchy of the body-surface-ring-edge-point.

mesh: is an important concept of digital modeling processing. One three-dimensional model is a three-dimensional model in which a plurality of triangles are combined at different angles (common edges or corners), and each triangle at the periphery constitutes a triangular mesh. mesh is typically a discrete result of BREP, which is the type of data required for rendering a display.

Stretching and shaping: a common way of three-dimensional modeling is to manufacture a three-dimensional shape by drawing a cross-sectional shape of a model on a sketch plane and then specifying a stretching height.

Sketch: english is named Sketch and is a two-dimensional graphic associated with a solid model. The function can create a sketch plane in any one of the required planes, and thus a sketch. The concept of constraint is added in the drawn sketch, and the graph in the sketch can be changed by modifying the constraint. Using the sketch tool, a user can draw an approximate curve profile, and after adding an accurate constraint definition, the intent of the design can be fully expressed. The established sketch can also be stretched, rotated and the like by using a solid modeling tool to generate a solid model related to the sketch. When the sketch is modified, the associated entity model is automatically updated.

Hard-fitting: means that in addition to the infrastructure that must be satisfied, a fixed and immovable ornament is added to the surface or inside of the building in order to satisfy the structural, layout, functional, and aesthetic needs of the house.

The conventional way of hard-fitting stretch molding is as follows: firstly, constructing a boundary representation (a boundary representation schematic diagram shown in fig. 2) corresponding to a two-dimensional sketch panel (namely the two-dimensional sketch panel shown in fig. 1) one by one; the corresponding regions in the boundary representation shown in fig. 2 are then stretched one by one according to the projected height (i.e., stretched height) of each region marked in the boundary representation schematic shown in fig. 2. As shown in fig. 3, the left drawing includes a region with a protrusion height of 100, and the right drawing includes a region with a protrusion height of 200, and two stretching molding needs to be performed on the two regions shown in fig. 2 respectively, so as to obtain a schematic diagram of the final stretching molding shown in the right drawing of fig. 3.

Because all the areas shown in fig. 3 are topologically connected together, this stretch modeling approach requires a full computation of the data for each area in the two-dimensional sketch panel and boundary representation each time the design is modified and redrawn. When the design diagram is complex, the number of the areas is increased, so that a great deal of computing resources are consumed for each design and modification of the design diagram, the design and modification process is slower and slower, and the performance cost is higher.

In view of this, an embodiment of the present application provides a processing method for a design drawing, where a plurality of target areas to be stretched may be obtained from a target two-dimensional sketch panel, each target area includes an area identifier, a stretching height, and coordinates of vertices and edges forming each target area, and then the plurality of target areas are encoded based on the coordinates of vertices and edges forming the plurality of target areas, the stretching height, and the corresponding area identifiers, so as to obtain an encoded representation of each target area. In this way, according to the coded representation of each target area, whether each target area is a newly drawn area or not can be determined from the target buffer space storing the coded representation of the stretch model obtained by stretching the plurality of areas drawn in the target two-dimensional sketch panel, if the boundary representation of the stretch model corresponding to the coded representation of the first target area in the plurality of target areas exists in the target buffer space, the boundary representation of the stretch model corresponding to the first target area can be directly obtained from the target buffer space, so that the design diagram corresponding to the target two-dimensional sketch panel is generated based on the boundary representation of the stretch model corresponding to the first target area, the need of stretching the first target area again is avoided, the calculation resources occupied by the boundary representation of the stretch model obtained after stretching the first target area and the calculation are reduced, and the performance cost of the design diagram corresponding to the target two-dimensional sketch panel in the design and modification process is further saved. Specifically, in the present application, a processing method of a design drawing is provided, and the present application relates to a processing apparatus of a design drawing, an electronic device, and a computer-readable storage medium, which are described in detail in the following embodiments one by one.

The target two-dimensional sketch panel is used for drawing a two-dimensional design drawing, and coordinates of vertexes and edges of each target area are drawn on the target two-dimensional sketch panel and can be obtained based on a two-dimensional coordinate system built in the target two-dimensional sketch panel. And each time a target area is drawn, an area identifier for uniquely identifying the target area can be automatically allocated to the target area, and the stretching height of each target area can be set by a designer. Fig. 5 is a schematic diagram of a hard-packed two-dimensional sketch according to an exemplary embodiment of the present application, where the hard-packed two-dimensional sketch shown in fig. 5 includes 18 target areas to be stretched, each target area has a corresponding area identifier, a stretching height (i.e., a protrusion value shown in fig. 5), and coordinates of vertices and edges constituting the target area, where the coordinates of the area identifier and the vertices and edges constituting the target area may not be displayed in the hard-packed two-dimensional sketch, and may be obtained from detailed information of each target area (for example, clicking each target area may display detailed information of each target area).

Step 420, encoding the plurality of target areas based on coordinates of vertices and edges constituting the plurality of target areas, the stretching heights, and the corresponding area identifications, to obtain encoded representations of the plurality of target areas.

The side line may include at least one of a line segment, a circle and an arc, the line segment may be represented by a start point coordinate and an end point coordinate, the circle may be represented by a center point coordinate and a radius, and the arc may be represented by a center point coordinate, a radius, an arc start point coordinate and an arc end point coordinate. Based on the embodiment of the application, line segments, circles and arcs can be encoded.

In some exemplary embodiments, when the plurality of target regions include only edges, encoding the plurality of target regions based on coordinates of vertices and edges that make up the plurality of target regions, a stretch height, and corresponding region identifications, resulting in encoded representations of the plurality of target regions, comprising:

encoding the vertexes of the plurality of target areas based on coordinates of vertexes constituting the plurality of target areas to obtain the encoding of the vertexes of the plurality of target areas;

and encoding each target area in the plurality of target areas based on the line segment codes, the area identifiers, the stretching heights and the preset area codes in the plurality of target areas to obtain the encoding representation of each target area in the plurality of target areas.

As an example, vertices are encoded in x.tofixed (3) -y.tofixed (3), where x and y are the abscissa and ordinate, respectively, of the vertex in a two-dimensional sketch panel, ".tofixed (3)" is used to indicate that the last 3 bits of the decimal point are reserved, and it should be understood that ". ToFixed (3)" is merely an exemplary illustration and does not constitute a limitation on the precision of the vertex coordinates.

As an example, the line segment is encoded in a manner of 'l2d' - (start point encoding) - (end point encoding), where 'l2d' is an example of a preset line segment code, and no limitation is imposed on the preset line segment code. The starting point code is obtained by the method that the starting point of the line segment is obtained according to the method that the vertex is coded, and the end point code is obtained by the method that the end point of the line segment is obtained according to the method that the end point is coded. The coding mode of each target area is 'f2d' -face.id-face.height- (coding of all sides of the target area), wherein 'f2d' is an example of a preset area code, face.id is an area identifier of the target area, face.height is the stretching height of the target area, and all sides of the target area are all line segments forming the target area.

In some exemplary embodiments, when the plurality of target areas include only edges and circles, encoding each target area of the plurality of target areas based on a line segment encoding, an area identification, a stretching height, and a preset area code of each target area of the plurality of target areas to obtain an encoded representation of each target area of the plurality of target areas, including:

when circles exist in the side lines forming the plurality of target areas, acquiring circle center point codes of the circles of the target areas in the plurality of target areas from the codes of the vertexes of the plurality of target areas, and determining the radius of the circles based on the coordinates of the side lines forming the plurality of target areas;

and encoding each target area in the plurality of target areas based on line segment encoding, circle encoding, area identification, stretching height and preset area codes of the plurality of target areas to obtain encoding representation of each target area in the plurality of target areas.

As an example, the circle is encoded in the form of 'c2d' - (circle center point code) -radius. The center point coding can adopt a vertex coding mode, namely, the codes are x.tofixed (3) -y.tofixed (3), x and y are respectively the abscissa and the ordinate of the center point in the two-dimensional sketch panel, the ". ToFixed (3)" is used for indicating that 3 bits after the decimal point is reserved, and the 'c2d' is an example of a preset circle code. It should be understood that ". ToFixed (3)" is only an exemplary illustration and does not constitute a limitation on the precision of the center point coordinates and radius. The coding mode of each target area is 'f2d' -face.id-face.height- (the coding of all sides of the target area), wherein 'f2d' is an example of a preset area code, face.id is the area identifier of the target area, face.height is the stretching height of the target area, and all sides of the target area are all line segments and circles forming the target area.

In some exemplary embodiments, when the plurality of target areas include only edges and arcs, encoding each target area of the plurality of target areas based on line segment encoding, area identification, stretching height, and a preset area code of each target area of the plurality of target areas, to obtain an encoded representation of each target area of the plurality of target areas, including:

when an arc exists in the side lines forming the plurality of target areas, acquiring center point codes, starting point codes and end point codes of circles of the target areas in the plurality of target areas from the codes of the vertexes of the plurality of target areas, and determining the radius of the arc based on the coordinates of the side lines forming the plurality of target areas;

and encoding each target area in the plurality of target areas based on line segment encoding, arc encoding, area identification, stretching height and preset area codes of the plurality of target areas to obtain encoding representation of each target area in the plurality of target areas.

As an example, the arc code is 'ca2d' - (circle center point code) -radius, toFixed (3) -start point code-end point code. The center point code, the starting point code and the end point code can all adopt a vertex code mode, namely, the codes are x.tofixed (3) -y.tofixed (3), x and y are respectively the abscissa and the ordinate of the center point/the circular arc starting point/the circular arc end point in the two-dimensional sketch panel, the · toFixed (3) "is used for indicating that the 3 bits after the decimal point is reserved, and 'ca2d' is an example of a preset circular arc code. It should be understood that ". ToFixed (3)" is only an exemplary illustration and does not constitute a limitation on the center point coordinates, the arc starting point, the arc ending point, and the radius accuracy.

As an example, the encoding mode of each target area is 'f2d' -face.id-face.height- (encoding of all sides of the target area), where 'f2d' is an example of a preset area code, face.id is an area identifier of the target area, face.height is a stretching height of the target area, and all sides of the target area may include a line segment and an arc.

According to the embodiment of the application, the coded representation of the target area is used as the basis for whether the boundary representation of the stretching modeling corresponding to the target area exists in the target cache space, and if the boundary representation of the stretching modeling corresponding to the target area exists in the target cache space, the boundary representation can be directly obtained, so that the calculation resources consumed for carrying out pulling body operation on the target area and calculating the relevant reference of the stretching modeling can be saved.

Step 430, obtaining a boundary representation of the stretch style corresponding to the encoded representation of the first target region from the target buffer space corresponding to the target two-dimensional sketch panel.

The first target area is a target area which exists in a target cache space and is indicated by a boundary indication of a corresponding stretching model in a plurality of target areas, and the target cache space stores the encoding indication of the stretching model which is obtained by stretching the plurality of areas drawn in the target two-dimensional sketch panel.

Step 440, generating a design drawing corresponding to the target two-dimensional sketch panel based on the boundary representation of the stretch build corresponding to the first target region.

In some exemplary embodiments, if there are some target areas that have not been generated within a historical period of time in the plurality of target areas, a stretching operation may be performed based on the encoded representations of the target areas to obtain boundary representations of corresponding stretching builds, so that a design drawing corresponding to the template two-dimensional sketch panel is quickly generated based on the boundary representations of the newly generated stretching builds and the boundary representations of the stretching builds stored in the target cache space. Specifically, based on the boundary representation of the stretch build corresponding to the first target area, generating a design drawing corresponding to the target two-dimensional sketch panel includes:

When a second target area exists in the plurality of target areas, stretching the second target area based on the coded representation of the second target area to obtain a boundary representation of a stretching model corresponding to the second target area, wherein the second target area is a target area which does not exist in the target cache space and is represented by the boundary representation of the stretching model corresponding to the coded representation in the plurality of target areas;

and generating a design diagram corresponding to the target two-dimensional sketch panel based on the boundary representation of the stretching modeling corresponding to the first target area and the boundary representation of the stretching modeling corresponding to the second target area.

The drawing model is a mode of generating a corresponding three-dimensional model based on the shape and the drawing height of a two-dimensional region in a two-dimensional design sketch in the two-dimensional sketch panel shown in fig. 5.

According to the embodiment of the application, the corresponding relation between the coding representation and the boundary representation of the stretching modeling is utilized, only the stretching modeling is carried out on the target area which does not exist in the target cache space, and the calculation cost of the stretching modeling is saved.

In some exemplary embodiments, since the boundary representation of the stretch builds corresponding to the first target region and the boundary representation of the stretch builds corresponding to the second target region are both original representations of the region shape, these representations cannot be directly displayed to the user, and therefore rendering operations based on the data of these original representations are also required. Specifically, generating a design drawing corresponding to the target two-dimensional sketch panel based on the boundary representation of the stretch build corresponding to the first target area and the boundary representation of the stretch build corresponding to the second target area, including:
