摘要: Embodiments are described herein for determining a stabilization plane to reduce errors that occur when a homographic transformation is applied to a scene including 3D geometry and/or multiple non-coplanar planes. Such embodiments can be used, e.g., when displaying an image on a head mounted display (HMD) device, but are not limited thereto. In an embodiment, a rendered image is generated, a gaze location of a user is determined, and a stabilization plane, associated with a homographic transformation, is determined based on the determined gaze location. This can involve determining, based on the user's gaze location, variables of the homographic transformation that define the stabilization plane. The homographic transformation is applied to the rendered image to thereby generate an updated image, and at least a portion of the updated image is then displayed.
摘要翻译: 本文描述了用于确定稳定平面以减少当将单色变换应用于包括3D几何和/或多个非共面的场景的场景时发生的误差的实施例。 这样的实施例可以用于例如在头戴式显示器(HMD)装置上显示图像时,但不限于此。 在一个实施例中,生成渲染图像,确定用户的注视位置,并且基于所确定的凝视位置来确定与同形变换相关联的稳定平面。 这可以涉及基于用户的注视位置确定定义稳定平面的同形变换的变量。 将同形变换应用于渲染图像,从而生成更新的图像,然后显示更新的图像的至少一部分。
