Problems solved by technology

[0005] (1) There is no similar software in the prior art that can numerically evaluate the sense of open space;
[0006] (2) Existing software numerically obtains users’ evaluation of the openness of space by directly asking a large number of users to obtain evaluations. The process is time-consuming and laborious; and it needs to organize a large number of users to participate. It is widely used in the daily design process of designers

Embodiment 1

[0080] The present invention realizes based on the following basic principles:

[0081] 1. When space users evaluate the openness of space, it is mainly based on the visual information in their visual threshold.

[0082] 2. According to the visual perception model, the visual information received by space users mainly comes from the reflected light of surrounding material interfaces (such as furniture, walls, etc.), so it contains the information of these material interfaces.

[0083] 3. Effective visual information for the evaluation of spatial openness mainly includes the distance of the material interface, the complexity of the material interface, the material of the material interface, and the color of the material interface.

[0084] 4. Space users do not disperse their attention evenly to the information in the visual threshold, but concentrate more attention around the focal point of sight, and are more likely to ignore the information at the edge of the visual threshol...

Embodiment 2

[0086] The simulation of the openness of the field of view provided by the embodiment of the present invention needs to simulate the user's visual attention distribution, specifically including:

[0087] The simulation of the openness of the visual domain needs to simulate the user's visual attention distribution. Assume that for each viewpoint O, with the viewpoint O as the end point, within the range of three-dimensional angles confirmed according to the set viewing angle, received images from the surface of the evaluated model in the visual domain The n reflected rays of , in the parametric model, are represented as a line segment L connecting the viewpoint and a certain point on the surface of the evaluated model;

[0088] Starting from each viewpoint O, the way to control the distribution of reflected light within the viewing angle is as follows: set the viewing angle as A, take the vector represented by the center of the viewing angle as the normal line, form a visual pro...

Embodiment 3

[0098] The present invention has already been partially adopted by practitioners in the design industry and has commercial cooperation cases. On the facade of an office building with a main orientation to the west (such as Figure 7 a) During the design process, since the lightweight concrete façade needs to be closed to the sun while maintaining the openness of the interior space, the design team divides the standard floor into grids and uses grids for each grid of the entire standard floor. This method visualizes the numerical value and makes a horizontal comparison of several different facade designs (such as Figure 7 b). In the application of this case, the weighted values ​​of transparency, material properties and outdoor light are not adopted. This case has been built (such as Figure 7 c).

Abstract

The invention belongs to the technical field of software design, and discloses an information processing method based on a three-dimensional parameterized model of a building space for a sense of openness in a building, setting a view field and importing the view field into the parametric model that includes information on the interface of surrounding materials. Information data; evaluate the validity of the parametric model based on the positional relationship between the viewpoint and the material interface in the visual threshold, whether the geometric shape of the material interface is complete, and whether the material setting of the material interface is complete; if it is invalid, ask the user to reset the parameterization Model; select the parametric model object in the measurement space, and set the object material; check whether the material setting of the measurement object is complete; output the evaluation results of the openness of the architectural space. The invention enables the designer to numerically calculate and compare the openness of different design schemes in a certain space by using the existing architectural computer model; without the participation of a large number of users, the tediousness and complexity of the evaluation process is reduced, and the Data breach problem.

Description

technical field [0001] The invention belongs to the technical field of software design, and in particular relates to an information processing method based on a three-dimensional model for the sense of openness in architectural space. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: in the process of architectural design, interior design, urban design, etc., it is often necessary to comprehensively evaluate a certain space, and one of the important evaluation indicators is the sense of openness, that is, the space looks Is it big or small. Especially in complex space design, there is a need for an objective numerical evaluation of the openness of space beyond the subjective judgment of the designer, which can be integrated into the current workflow commonly used by designers. [0003] At present, there is no similar software that can numerically evaluate the sense of openness in space. The main reason is that ...
