Problems solved by technology

In addition, when there are more filtering conditions, the depth of the scene tree is increased, which affects the performance of traversing the scene, and may not achieve the effect of quickly filtering and displaying rendering objects.

Abstract

The invention provides a rendering object filtering method and a rendering object filtering device. The rendering object filtering method comprises the steps as follows: defining extended attributes for the rendering objects; generating at least one filter according to conditions for filtering the rendering objects and the extended attributes of the rendering objects; determining whether to add any rendering object to a rendering queue according to the at least one filter and the extended attributes of the rendering object when the rendering object of the multiple rendering objects is filtered. With adoption of the technical scheme, the rendering objects can be filtered rapidly.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional display, in particular, to a filtering method for rendering objects and a filtering device for rendering objects. Background technique [0002] Changing the visibility of rendered objects is the most basic function of a 3D display engine. For example, in a three-dimensional BIM (Building Information Modeling, Building Information Modeling) application, a large number of rendering objects are included in the model, and the rendering objects may occlude each other. In order to view the model easily, it is often necessary to filter and display rendering objects according to floor, major, rendering object category, classification code, etc. [0003] In related technologies, the corresponding rendering object is searched out according to the filter condition. The rendering object has a Bool-type attribute indicating visibility, such as Visible. When Visible is true, the rendering obj...
