摘要： Embodiments of the present disclosure relate to a process for creating contact shadows. Specifically, embodiments of the present disclosure include converting an original image to an initial shadow image, cropping the initial shadow image to obtain at least two slices of the initial shadow image, blurring the slices, overlaying the slices to create a combined shadow image, compressing the combined shadow image to create a contact shadow, and displaying the contact shadow on a virtual surface relative to the original image. Further, a user can change the amount of blurring the contact shadow has, the apparent offset from the surface, the perspective, the opacity, and the color of the contact shadow.

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.
摘要翻译：本公开的实施例涉及一种用于在数字画布中的虚拟曲面上产生数字对象的模拟阴影的方法。通过从数字对象中删除颜色来生成基本图像。通过识别数字画布上的虚拟曲面并将基础图像投影到虚拟曲面上来生成初始的阴影图像。通过将初始阴影图像模糊到多个模糊图像中的每一个的模糊的不同百分比来生成多个模糊图像。应用数学函数来产生虚拟曲面上的模拟阴影，其中数学函数在虚拟曲面上的不同点处在初始阴影图像和多个模糊图像之间插值。
