Product icons / 产品图表

Product icons are the visual expression of a brand’s products, services, and tools. Simple, bold, and friendly, they communicate the core idea and intent of a product. While each product icon is visually distinct, all product icons for a given brand should be unified through concept and execution.

产品图标是品牌的产品、服务、工具的视觉表现。简单、明了、友好的产品图标能够向用户传递出产品的核心理念。虽然每个产品的图标在视觉上是有着不同的表现,但所有的产品图标应该以一种相同的理念和形式进行表现。

Use these guidelines as a starting point to ensure that your product icon colors and key elements reflect your brand identity.

在刚刚开始的就是用这些准则来保证你产品图标的颜色和关键元素能够反映出你的品牌特色。

Material icons

Design approach / 设计原则

Product icon design is inspired by the tactile and physical quality of material. Each icon is cut, folded, and lit as paper would be, but represented by simple graphic elements. The quality of the material is sturdy, with clean folds and crisp edges. The matte-like finish interacts with light through subtle highlights and consistent shadows.

产品图标的设计灵感源自于材料的触觉和材料的物理质量。每个图标都可以使用简单的图形元素进行展现,甚至于可以在纸张的基础上使用剪切,折叠,采光等手法进行图标的复原。材料应该是有着简洁的折痕,和清晰的边缘,并且材料本身的质量应该有足够的结实(不可穿透)。磨砂状的表面是通过微妙的高光和连贯的阴影相互作用形成的。

Product icon grid / 产品图标栅格

The product icon grid has been developed to facilitate consistency and establish a clear set of rules for the positioning of graphic elements. This standardization results in a flexible but coherent system.

使用产品图标栅格是为了方便的建立一套清晰的规则来确定图形元素的位置,以保证图标的统一性。如果你建立了这种标准,那么你就可以根据自己的需求创建一个灵活又统一的图标系统。

Grid / 栅格

Keylines / 关键线

Keyline shapes / 关键线 形状

Keyline shapes are the foundation of the grid. By using these core shapes as guidelines, you can maintain a consistent visual proportion across related product icons.

关键线形状是基于栅格创建的。通过使用核心参考,你可以保证你的产品图标有着统一的视觉比例。

Square / 正方形

  • Height: 152dp
  • Width: 152dp

Circle / 圆形

Diameter: 176dp

Vertical rectangle / 垂直的长方形

  • Height: 176dp
  • Width: 128dp

Horizontal rectangle / 水平的长方形

  • Height:128dp
  • Width:176dp

DP unit grid / 以DP为单位的栅格

Android expects product icons to be provided at 48dp, with edges at 1dp. When you create the icon, maintain the 48-unit measure, but scale it to 400% at 192 x 192 dp (the edge becomes 4dp).

安卓希望产品提供变长为48dp的图标,一个边长的基本单位为1dp。当你创建一个图标,他的一条边长保持在48dp,如果放大四倍,变长则变为192dp(基本单位变为4dp)。

Any scaling done to the original will scale the image up or down proportionally. By maintaining the unit ratio, you preserve sharp edges and correct alignment when the scale is reduced.

对原石尺寸进行等比的放大或缩小时,只要保持基本单元的比例不变,你就能在不同尺寸的情况下,减少因为放大或缩小改变图片而缺失的图标细节,并且保持图标尽可能的清晰正确。

1:1 Unit grid / 1:1 单元栅格

Geometry / 几何

Preset standards have been determined for specific keylines: circle, square, rectangle, orthogonals, and diagonals. This small palette of universal and simple elements has been developed to unify product icons and systemize their placement on the grid.

使用关键线围城的几个基本形状作为预设的标准:圆形、正方形、长方形、正交、对角。通过哪些简单的图形元素和调色板已经可以在栅格上开发统一的产品图标或系统图标了。

Product icon anatomy / 产品图标剖析

Product icon anatomy describes the graphic elements that make up a product icon. The consistency of these elements across icons for a given brand is critical in maintaining a shared visual language. Familiarity with these elements makes it easier to understand characteristics of each logo and subtle differences between them. It will also help educate your eye to recognize the underlying structure of logo designs.

产品图标剖析是解释说明组成产品图标的图形元素。那些图标中一致的元素是维持品牌统一视觉语言的关键。熟悉这些元素可以更容易的理解每个标示和它们之间细微差别的特性。同时也能帮助你的眼睛更好的认识标示设计的底层结构。

Lighting 采光

Within the material environment, virtual lights illuminate the scene and allow objects to cast shadows. A top light cast on material elements creates a contact shadow while highlighting the top and bottom edges. An angled light reinforces the sense of surface across the elements.

在材料环境中,虚拟的灯光照亮场景并使物体投射阴影。有关材料元素的俯视投光创建一个有联系的阴影同时突出了顶部和底部边缘。倾斜的光线增强了元素表面的效果。

Top / 顶部

Shadows 阴影

For a product icon, the top light from above casts a soft shadow surrounding an element lightly on the top and left. The shadow is slightly heavier below and to the right. This shadow is always contained within the icon’s silhouette.

对于一个产品图标,通过顶部照射下来的光线所产生的阴影是围绕着元素周围,并且左侧和顶部是比较淡,而右侧和底部的阴影则略深。这个阴影始终在这个图标的轮廓内显示,不能超出轮廓。
