The application provides a local information pickup method of a rendering entity. Referring to fig. 1, a method flow diagram of an embodiment of a local information pickup method of a rendering entity according to the present application is shown. The method may be performed by an electronic device, which may be implemented in software and/or hardware. The local information pickup method of the rendering entity comprises the following steps:

The user can render the three-dimensional entity during drawing or design, and the three-dimensional entity is gridded during rendering, so that the geometric features of the three-dimensional entity are lost, and the user cannot pick up the correct local geometric features of the three-dimensional entity.
According to the method, geometric characteristics of a rendering entity (for example, a three-dimensional rendering entity) are deduced reversely through a modeling platform, specifically, when a user clicks the rendered entity through a mouse cursor, an intersection point of the mouse cursor clicking in the entity is determined, due to the existence of a tolerance mechanism, when a plurality of entities are very close to each other, the entity selected by the mouse cursor is not unique within the tolerance range, namely, the plurality of rendering entities can be selected by the mouse cursor, so that a target rendering entity selected by the mouse cursor needs to be acquired, the target rendering entity refers to the entity closest to a viewpoint, the target entity can be determined by utilizing preconfigured priority logic, and the priority logic can be configured according to the distance between the entity and the intersection point and the type of the entity.
