Rendering – Industrial Machine

Some people like to make photo-realistic images out of 3D models. It’s very cool to see something I’ve made in SketchUp turn into something which looks real.

I enjoy making models in SketchUp. When I am modeling something which already exists, I am effectively reverse engineering the object. In doing that, often I can understand better how it works and why it works that way.

Rendering is something very different. Changing the characteristics of the surfaces and changing the light sources makes the picture more realistic, informative or interesting. The process is iterative in that a light source can create another light source in the form of a reflection. Then that reflection’s presence has to be accounted for by the program. There is judgment and subtlety involved in preparing a rendering. The computing power and time is huge, and while it’s not too hard to do a decent job, doing an excellent job is very challenging. Then, if you are doing it in a 3D animation, each frame of the animation must be rendered, and that takes even longer.

In this example, I was planning a future workshop layout and I wanted to see how I might fit a knife belt sander into the plan. I only needed a rough model for this purpose, but as I tend to do, I went overboard and made it as close to perfect as I could. I posted it as part of a contest in the SketchUcation forums.

Similarly, there’s a rendering of a wrist watch which I modeled here.

Good work. You might probably see the same item as your industrial machine here LSG Industrial
