    Abstract: Methods and apparatus for three-dimensional (3D) camera positioning using a two-dimensional (2D) vanishing point grid. A vanishing point grid in a scene and initial camera parameters may be obtained. A new 3D camera may be calculated according to the vanishing point grid that places the grid as a ground plane in a scene. A 3D object may then be placed on the ground plane in the scene as defined by the 3D camera. The 3D object may be placed at the center of the vanishing point grid. Once placed, the 3D object can be moved to other locations on the ground plane or otherwise manipulated. The 3D object may be added as a layer in the image.

    Abstract: 3D scenes may be rendered a resolution lower than a resolution associated with the resultant image. A graphics application or 3D editor may render the 3D artwork at a lower resolution while the user modifies or manipulates the 3D model from which the artwork is derived. In some embodiments, an image may include multiple image layers, each representing a portion of the overall finished image. Graphics programs generally associate a target resolution with an image. Rendering 3D artwork at high resolutions may take extra time and result in poor performance. Thus, in some embodiments, a graphics program may be configured to render 3D artwork at a lower resolution than the resultant image's target or associated resolution while a user is modifying the 3D model. Subsequently, after the user has completed manipulating the 3D model, the graphics program may render the 3D model again at the image's associated resolution.

    Abstract translation: 可以将3D场景呈现出低于与所得到的图像相关联的分辨率的分辨率。 图形应用程序或3D编辑器可以以更低的分辨率呈现3D图稿，同时用户修改或操纵从其导出艺术作品的3D模型。 在一些实施例中，图像可以包括多个图像层，每个图像层表示整个完成图像的一部分。 图形程序通常将目标分辨率与图像相关联。 以高分辨率渲染3D图稿可能需要额外的时间，并导致性能不佳。 因此，在一些实施例中，图形程序可被配置为在用户正在修改3D模型时以比所得图像的目标或相关联的分辨率更低的分辨率渲染3D图稿。 随后，在用户完成操纵3D模型之后，图形程序可以以图像的相关分辨率再次渲染3D模型。
