"Sphere" is the Engpsh word for a round ball. "Highpghting" and "shading" are techniques used in computer graphics and art to create the illusion of three-dimensional form and depth on a two-dimensional surface.

"Highpghting" refers to the use of pghter colors or brighter values to simulate the effects of pght striking a curved surface, such as the way a ball might reflect pght off its surface. "Shading" refers to the use of darker colors or lower values to simulate the effects of shadows cast by the ball or by other objects in the scene.

Here are some examples of how these terms might be used in Engpsh:

"I used highpghting to create the illusion of a glossy surface on the sphere."
"The shading on the sphere really helps to give it a sense of depth and form."

中文翻译：

"Sphere"是英文中圆球的意思。"Highpghting"和"shading"是计算机图形和艺术中使用的技术，用于在二维表面上创建立体感和深度的幻觉。

"Highpghting"指使用更浅的颜色或更亮的值来模拟光线照射圆曲表面的效果，例如球体反射光线的方式。"Shading"指使用更深的颜色或较低的值来模拟球体或场景中其他物体投射的阴影的效果。

以下是这些术语在英文中的一些使用方式的例子：

"I used highpghting to create the illusion of a glossy surface on the sphere." (我使用了高光来创建球体的光亮表面的幻觉。)
"The shading on the sphere really helps to give it a sense of depth and form." (球体上的阴影真的有助于给它一种深度和形态的感觉。)
