Embodiment 1

[0036] figure 1 It is a schematic flow diagram of the element placement method according to the first embodiment of the present application. The method may be executed by a software and / or hardware device. For example, the device may be an electronic device where a three-dimensional scene editor is located. Such as figure 1 As shown, the content recommendation method includes:

[0037] S101. Receive a user's movement operation on an element.

[0038] In this embodiment, the element is the basic operation unit in the 3D scene editor. For example, the 3D scene editor is an automatic driving scene editor, and the elements can be vehicles, pedestrians, roadblocks, trees, buildings, traffic lights, roads, and other objects that users can use to build an automatic driving scene. For example, the 3D scene editor is an architectural model editor, and the elements can be walls, doors and windows, stairs, furniture, and other object models that users can use to construct architectural mode...

Abstract

The invention discloses an element placement method, device and equipment of a three-dimensional scene editor and a storage medium, and relates to the field of automatic driving. The specific implementation scheme is as follows: receiving a moving operation of a user on an element, wherein the moving operation is used for indicating a target position of the element; determining the intersection point of the ray pointing to the target position from the origin of the camera coordinate system of the three-dimensional scene editor and the ground in the interface of the three-dimensional scene editor as the adsorption position of the element; elements are placed at the adsorption locations. According to the method, the operation complexity of the three-dimensional scene editor is reduced, and the processing efficiency is improved.

Description

Technical field [0001] The embodiments of the present application relate to data processing technology, and in particular to an element placement method, device, equipment, and storage medium of a three-dimensional scene editor, which can be used in the field of automatic driving. Background technique [0002] In modeling scenarios in various fields, scene generation with specific semantics is often achieved by manual editing in the scene editor. In order to simplify the operation threshold of scene editing, the main application scenarios of scene editors have always been based on two-dimensional Flat map. However, for some specific application scenarios, such as multi-storey underground parking lots, roads with high slopes, etc., scene design based on two-dimensional flat maps will not meet the needs of accurately constructing scenes, so scene editing based on three-dimensional space maps appears Especially necessary. [0003] At present, mainstream 3D modeling editors generally...
