NINEIDEA：简单来说，产品设计渲染效果有这几个好处。
提前 “看到” 真实效果：不用等做出实物，电脑里就能把设计变成超逼真的图片 / 视频，比如手机的金属质感、汽车的烤漆光泽，甚至放在客厅里啥样，一眼看明白，避免 “想的和做的不一样”。
省钱省时间：早期改设计不用砸钱做模型，改改参数、调调材质，几分钟就能看到新效果，比如想试试红色还是蓝色外壳，渲染一下秒切换，省了打样的钱和时间。
沟通神器：设计师跟老板、客户、工程师说不清的时候，一张渲染图甩过去，“看，我想做的就是这样！”，减少 “你懂我意思吧” 的无效沟通，比如耳机的佩戴角度、按钮位置，一看就懂。
抠细节神器：能把设计放大 100 倍看，比如缝隙是不是太宽、曲面过渡自然不，甚至光影有没有 BUG，提前发现问题，比如 “手机摄像头模组反光太丑”，渲染时就能调。
提前 “卖” 产品：还没量产呢，就能做出广告级效果图、使用场景视频（比如杯子装咖啡在阳光下的样子），帮市场部门提前宣传，甚至拿给用户调研 “这版你想买吗”，提前预判市场反应。
说白了，渲染就像给设计开了个 “预览外挂”，让大家提前验货、提前改、提前卖，少踩坑、少花钱，效率拉满！
NINEIDA: Simply put, product design rendering effects have several major benefits.
Seeing the real effect in advance: without waiting to make a physical object, the design can be turned into super realistic pictures/videos on the computer, such as the metallic texture of a phone, the gloss of a car’s paint, and even what it looks like in the living room. It is easy to understand at a glance, avoiding “thinking and doing differently”.
Save money and time: In the early stages of designing, there was no need to spend money on making models. By changing parameters and adjusting materials, new effects could be seen in just a few minutes. For example, if you want to try the red or blue shell, you can switch between rendering in seconds, saving money and time on prototyping.
Communication tool: When a designer can’t explain clearly to their boss, client, or engineer, they throw a rendered image over and say, “Look, this is what I want to do!” to reduce ineffective communication of “you know what I mean, right?” For example, the wearing angle and button position of the headphones can be understood at a glance.
Detail picking tool: It can magnify the design by 100 times, such as whether the gaps are too wide, whether the curved transitions are natural, and even whether there are any bugs in the light and shadow. It can detect problems in advance, such as “the reflection of the phone camera module is too ugly”, which can be adjusted during rendering.
Sell “products in advance: Even before mass production, you can create advertising grade renderings and usage scenario videos (such as what a cup of coffee looks like in the sunlight) to help the marketing department promote in advance, and even conduct user research on” Do you want to buy this version “to predict market reactions in advance.
Simply put, rendering is like opening a “preview cheat” for design, allowing everyone to inspect, modify, and sell in advance, avoiding pitfalls and spending less money, and maximizing efficiency!
