CURVED SHADOWS IN VISUAL REPRESENTATIONS

摘要

Embodiments of the present disclosure relate to a method for generating a simulated shadow for a digital object on a virtual curved surface in a digital canvas. A base image is generated by removing color from the digital object. An initial shadow image is generated by identifying the virtual curved surface on the digital canvas and projecting the base image onto the virtual curved surface. A plurality of blurred images is generated by blurring the initial shadow image to different percentages of blur for each of the plurality of blurred images. A mathematical function is applied for generating the simulated shadow on the virtual curved surface, wherein the mathematical function interpolates between the initial shadow image and the plurality of blurred images at different points on the virtual curved surface.

1. A method performed by a processor for generating a simulated shadow of a digital object image on a virtual curved surface of a computer-implemented application having a presentation slide, comprising:
generating a base shadow image by removing color from the digital object image; based on the virtual curved surface, generating an initial curved shadow image by projecting the base shadow image onto the virtual curved surface; generating at least a blurred curved shadow image and a partially blurred curved shadow image by differentially blurring the initial curved shadow image; and generating the simulated shadow on the virtual curved surface by sampling, at different points on the virtual curved surface, from one or more of the initial curved shadow image, the blurred curved shadow image, or the partially blurred curved shadow image.
