Marc Joseph, trên trang  Young Architect, đã có bài viết nêu ra 12 điều bất cập khi là 1 "renderman".Khi mà ảnh 3D render vẫn được coi như là cách thức hiệu quả nhất để "liên lạc" với chủ đầu tư, việc diễn hoạ có vẻ như đang bị lạm dụng quá mức đến nỗi nhiều người quên mất vấn đề cốt lõi về tạo hình. Post nguyên bài này cho anh em tham khảo.

(Marc Joseph, from Young Architect)

1. You Will Lose Track of Time - Bạn sẽ mất thời gian
You can really get lost in your modelling. A whole work day can go by without you even realizing it. Worst of all, you can spend hours on a task that you expected to take a half an hour. In the end, you will find yourself staying later into the night while your coworkers punch out at 6.

Seen at Young Architect. More reasons after the break.

2. More Demands on Your Time - Phải đáp ứng nhiều yêu cầu hơn
There seems to be a very unfair expectation that employers have on the amount of time that it takes to complete a digital model. I have seen employers consistently assign a brand new 3D model to be completed and rendered for print in a two day period. While that may not seem like a short amount of time, we can easily forget that a considerable amount of time is going to be spent tweaking the vantage points and materials. Also, the employer will inevitably be requesting changes to the design or look once they see your progress prints.

3. The Employer Doesn’t Have Knowledge of the Software - Các nhà quản lý lại không hiểu biết về phần mềm.
There in lies maybe the biggest problem. Most of your supervisors will be older and have not been personally exposed to modelling software. They often feel as though computers have made things more instant or automated, when the truth of the matter is that computers have really just complicated things.

So as mentioned above, the employer will give you these assignments and constantly make changes to the model before you are done. Often times, the changes that they request will require near full remodels, so they can really be detrimental to getting renderings complete. This brings me to my next point

4. You Will Find Yourself Re-doing Things Over and Over - Bạn sẽ thấy mình làm đi làm lại một việc
As you present various schemes and changes to your clients, you will find that you will have to model the same things over and over again. It is not unusual to have to go through 3-5 different drawing files in one day.

5. You Have to Sweat the Details - Bạn phải vật lộn với một đống chi tiết
Aside from actually constructing the forms that make up the building massing, you also need to concentrate on those tedious details. Reflections, shading, material colors, mullions… you name it, are all items that must be coordinated into your rendering in order for it to come off as a believable form. Clients have little capacity for imagination and you really need to paint as clear of a picture as possible. The details are going to take up most of your time.

6. You Are On Your Own: No One Else Can Help You - Không ai có thể giúp bạn - bạn phải tự làm thôi
Unfortunately, digital models practically have individual signatures embedded into them. What I mean is that it is easy to tell that one person modelled one drawing and another person was the author of another. When you are presenting multiple schemes, the same person really needs to be developing each one. It is the only way to deliver a professional presentation to a client. This means that none of your colleagues can help you out with the work load.

7. You May Have Knowledge in One Software But Not Another - Bạn có thể có hiểu biết tốt với một phần mềm nhưng cái khác thì không
There are so many different 3D software out there. I could name nearly ten of them but there are constantly new programs coming out that trump the others. I personally was used to using Formz when I came out of school. My first firm used 3D Studio Max and expected me to hit the ground running. I ended up having to learn the new interface while trying to keep up with my assignments. This led to longer nights at work that I would have rather spent back home of at happy hour.

8. You Lose Your Personal Space - Bạn sẽ mất đi không gian riêng tư do thường xuyên bị "soi"
Because your boss will be wanting to make those changes, he is basically going to be sitting on your lap and punching holes in your LCD screen. They just get sucked into your computer screen while you are still sitting at your desk! They will be putting their faces 3 inches away from your screen so they can inspect your work and you will most likely get familiar with the smell of their breath. To make matters worst, they will just stand there while you are frantically making their changes, even though it may take you 10 minutes to do so. You really just have to sit there and take it because its hard to tell your boss to buzz off.

9. You Won’t Be Working on Important Tasks - Bạn sẽ không được tham gia những nhiệm vụ quan trọng
So while you are making pretty pictures, your friends in the office will be doing real work. Creating presentation images is indeed important and you will still be a valuable member of the team, but, in the end this won’t amount to anything more than an image that makes your client “oooh and ahh.”

10. You Will Learn Less - Bạn sẽ ít được trau dồi kiến thức chuyên môn
This is similar to the last point. While you are modelling, you won’t be doing any detailing, space planning, or structural coordination. Really, you are going to be missing out on all of those “important tasks” that will make you a more complete architect. There is no 3d Modelling section on the exams.

11. You Will Be Under-appreciated - Bạn sẽ không được đánh giá đúng
Because you won’t be involved in those other tasks that really result in a final set of working documents, your contribution won’t be recognized as much. 3D modelling is expected to be a simple automated process and the crazy amount of time you pour into your assignments will be diminished by your employers high expectations.

12. Professionals Do It Better - Dân chuyên nghiệp họ làm tốt hơn nhiều.
Seriously, they do. You could spend a solid month on a model and it won’t look as good as when a professional renderer works a day or two on the project. You don’t have the skill-set or the digital library to trump the professionals. From personal experience, I have seen a professional rendering firm model the entire Dubai Waterfront Development overnight…from scratch. These are the images that you have probably seen for a few years now, including the early images of the new world’s tallest building. That’s right, they were done in a span of one night! Could you possibly compete with that?
