Urban Night Illustration

由专筑网刘庆新编译

一个月前我首次建立Sketchup模型的时候就想制作一个城市夜景渲染图。我选中的区域是有着半透明玻璃的塔建筑和塔建筑下面有路灯的街道。昨晚我建立了模型，整晚都在用Kerkythea进行渲染。今天早上我花了8小时在PS中进行后期处理，是我有史以来花时间最长的一次。而且我还采用了一种非传统的视角，将塔楼的顶部和底部都切掉了。我将近景选在塔楼立面的半透明玻璃。下面是渲染图的分步操作。

因为模型的尺寸和灯的数量，我并没有提到我的电脑制作昏暗灯光的流程，Kerkythea渲染就花了一整夜时间才完成。

I’ve been wanting to do this illustration ever since I first built the Sketchup model a month ago. A couple of areas that I focused on was the semi-transparent glass in the tower and activating the streets down below. I set up the model last night and let it render in Kerkythea over night. I began post processing in PS this morning and finished about 8 hours later. In terms of time spent on post processing, this image is up there as one of the longest that I have done. I also chose a view that is somewhat unconventional in the sense that both the top and the bottom of the tower are cut off. I wanted the shot tighter on the tower facade focusing on the semi-transparent glass. The image is broken down further below.
Because of the size of the model and the amount of lights, not to mention the weak processing power of my computer, the Kerkythea rendering took all night to finish and then some.

Kerkythea Initial Rendering/Kerkythea初始渲染

在PS中，我首先创建了塔楼的半透明玻璃。开始我并不确定怎样操作，但是经过几次尝试，我渐渐得到了我想要的效果。流程非常简单，也许将来我会详细给大家解释。

Once in Photoshop, I first looked at creating a semi-transparent glass for the tower. I wasn’t real sure how it would turn out, but after some experimenting, I was able to get the look close to what I was imagining. The workflow is incredibly easy. I will see if I can put together a detailed explanation in the near future.

一旦玻璃看上去大体完成，我开始给建筑背景添加合适的纹理。我使用Google街道图找到大部分建筑立面，因为建筑在背景中是很小的，我不需要高像素的图。因此，街道画面会更充分。

Once the glass was looking half way decent, I moved to finding the correct textures for the background buildings. I used Google street view to find most of the building facades. Because the buildings are so small in the background, I didn’t need high resolution images. Therefore, the street view screen shots were more than sufficient.

接下来我开始制作街道。之前我只创建过很小的城市渲染图，发现制作一个成功的城市渲染图的关键在于有一个活跃的街道场景。后面的时间我就花在这里，但是我喜欢添加大量人物来完成这个“活跃的街道场景”图。

I next moved to the street. I have created only a few urban illustrations in my day, but I have found that the key to a successful urban rendering is having an active street life. In other words, adding brightly lit streets with lots of activity and movement. I ran out of time towards the end of the day, but I would have liked to add loads of people to complete the “active street life” vision.

最后一步包括花几个小时对所有窗户进行灯光渲染。虽然手头有电脑，但是我不能使用Kerkythea来制作灯光，不只是因为我没有这么高的电脑技能，即使有这个本领我也要花无休止的时间来准备Kerkythea模型，还要在建筑中放置所有的灯光。所以我手工对灯光进行一个个渲染操作。幸好这不是什么动脑筋的活儿，我可以边看锦标赛边添加光线。

The final step involved me spending hours painting light in all of the windows. With the computer that I have, there is no way that I could have rendered light using Kerkythea. Not only do I not have the computing power, but it would have taken me forever to prepare the Kerkythea model and place all of the lights within the buildings. Instead, I just painted in the lights one by one. Luckily, it’s mindless work which means I was able to watch the playoffs and paint at the same time.
