Yes, that’s right!! You really can see into the future!
And while clairvoyance can have its negative aspects (as in premonitions, omens, creepy “sixth sense” experiences, etc.), the kind of clairvoyance I can offer is definitely a positive experience.
How can I help you see the future? Through the medium of photorealistic 3D renderings! (of course).
Seeing the future isn’t easy. You have to begin with at least a vague idea of what you WANT to see in the future — some people might call that a dream. But starting from just the barest outline, we can work together to turn that outline (also known as a floorplan) into a 3D model with walls, doors, windows, and a roof. As the vision of the future becomes clearer, we can shade it in, giving it colors and textures, lighting it naturally and/or artificially, even landscaping, furnishing, and decorating it!
Eventually, a clear picture of your architectural future will begin to emerge. Your dreams will have taken shape, and you’ll be able to see your new or remodeled home as clearly as if you were standing in it — before a single shovelful of dirt has been dug or a single piece of drywall hung. Now THAT’s practical magic!
I’ve created 3D models of existing homes where I’ve measured and photographed the actual house in order to make an accurate model of it, and it’s always rewarding to feel like I’ve faithfully captured the essence of a house or a room. I’ve also created many 3D models for architects and builders far removed from my little corner of the world — buildings I will never see and so have no particular connection to or investment in (other than doing a great rendering for my client).
But there’s an entirely different feeling that accompanies creating a 3D version of someone’s dream — AND THEN SEEING IT ACTUALLY BUILT IN REAL LIFE. It’s sort of eerie — a sense of deja vu — to see something that has existed only in my mind and on my computer become bricks and mortar and sinks and toilets. It’s hard to describe, but it really does feel like I’ve seen into the future.
I had this experience recently in my own home when we had our 1935-vintage bathroom remodeled. I created detailed 3Ds of what I wanted the finished room to look like — and then got that eerie feeling as I saw my renderings slowly come to life as the remodel progressed.
Now maybe this shouldn’t come as such a surprise — I did design it, after all, so what did I expect them to build? But it happens every time with projects like this — I feel that somehow I’ve been able to glimpse the future and capture it in pixels.
Have you ever wished that you could see into the future? I can help.
All the marketing gurus say that every company needs a “big, audacious idea” as its driving mission and reason for doing what it does every day. Here’s mine for CastleView 3D:
Make 3D renderings as indispensable as blueprints or construction documents for any construction or remodeling project.
Before the blueprint was invented in the mid-1800s as a way of making copies of construction drawings, every architectural plan had to be painstakingly hand-drawn. But the new “technology” was quickly adopted as an obvious improvement on the old ways. Everyone could see the benefit — so why not use it?
My hope is that this same tale will someday be told about 3D CAD modeling and rendering for architectural designs. The technology exists — why not use it to best advantage?
Yet there still seems to be resistance to the widespread adoption of 3D rendering as a standard procedure in architectural design. Just today I got a call from a prospective client who was having trouble visualizing his new home from the plans his architect had drawn up. He asked the architect for 3D images, “like the ones I see on HGTV,” but the architect refused, saying he just didn’t do those. Luckily this guy was smart enough not to take “no” for an answer — always the mark of a true pioneer! And his internet search led him to me.
Despite the inevitable holdouts (probably folks who don’t have the time or inclination to learn 3D rendering techniques), I predict that some day soon 3D renderings will become a must for all architects and home designers — not an extra or an add-on, but simply an accepted cost of doing business, like producing blueprints or construction documents. I believe this will happen because savvy consumers will come to demand and expect it.
Nowadays, why should anyone expect a customer to be satisfied with a flat, 2-dimensional blueprint or plan, when we have the technology and expertise to show them their project in mouthwatering 3D detail?
My big, audacious idea is the driving force behind what I hope to accomplish with this blog and my other marketing communications — educating consumers of building and design services about their options. I want them to understand that 3D renderings aren’t just some TV magic on home design shows like “Hidden Potential”, but that they’re available to anyone who understands the value in “seeing it before you build it.”
“3D Renderings for All!” is my new motto.
When I’m discussing a project with a new client, I often get asked what the difference is between a “render” (or “rendering”) and a “raytrace.” Sometimes I use all three terms interchangeably, which I’m sure can be confusing. But are they actually different? If so, how?
Answers to these questions could (and do) fill entire books and webpages, but I’ll attempt a very simple explanation here (which will still be way too technical for a lot of folks!).
Computer rendering* is a general term for producing an image from a model constructed with 3D modeling software. 3D modeling involves creating a mathematical representation of a three-dimensional object. Once the model, or mesh, is created, it is possible to take a “camera view” of the object from any angle (hence the term 3D). The information from the 3D model is transferred to a rendering program to be processed and output as a digital image file, typically using a simple rasterization or scanline rendering method. Current processors can produce this type of rendering quickly and efficiently, pretty much in real time, and it is what is used in most computer gaming.
Raytracing is a specific type of rendering technique. The name refers to the way the computer creates the final image — by analyzing the light sources in the scene and computing the paths of the rays (photons) produced by those lights. The result is a very realistic image including reflections and caustics (light refractions through glass), resulting in lighting and shadows that are close to what would be observed in the real world. Raytracing algorithms simulate light realistically as it bounces between different objects, calculating the exact color of each pixel based on its material properties and the amount of light it is receiving. In raytracing, many different algorithms can factor into the computation of a pixel’s final shade, including the material’s absorption, reflection, transparency, translucency, and refraction characteristics.
Raytracing actually proceeds opposite to the way light normally travels, because it works backward, only calculating the paths of photons that actually intersect the camera’s view frame. Although this makes the process more efficient than if it actually traced the path of every photon emitted from every light source in the scene, it does not always yield the most realistic results. Other methods which combine both eye-based and light-based ray paths, such as photon mapping and bidirectional path tracing, can yield superior results, especially in scenes involving indirect lighting or caustics.
Rendering is generally less time- and computer-resource-intensive than raytracing. However, technology is improving rapidly and real-time raytracing will soon be an accessible reality.
So, are you still with me? What does all this technical stuff mean for someone who wants computer images of their new home or remodeling plans? An example can demonstrate the differences best. Here is a comparison of a render versus a raytrace of the same room. The first image is a Chief Architect rendered camera view of a great room and entryway with curving staircase. The second image is one I posted the other day, a raytraced image of the same space.
In the rendering, you can see that there is some differential shading of surfaces depending on their angle and the amount of light they are receiving. But overall the scene looks fairly flat. The lighting in the raytraced image is much more realistic — sunlight coming through the windows, reflections on the polished wood floor, and a greater sense of depth and dimension.
You can view another render-vs-raytrace example here.
Renders are fine for the initial stages of a project, when rough approximations of the look and feel of the space are sufficient for planning purposes. But once the major decisions have been made, final raytraces are what really bring the space to life and promote confidence in the material and design choices.
So there you have an oversimplified explanation of the differences between rendering and raytracing. I was enchanted and enthralled the first time I produced a simple rendering with my beginner-level Home Designer software. But once I learned how to create raytraces with Chief Architect’s POVray, and later on with Kerkythea and Thea Render, it was impossible to feel satisfied with anything less realistic again.
My sincere apologies to anyone who is more expert in this area than I am. I’m an intelligent, educated person, but thinking about the technical explanations for all this makes my brain hurt. I’ve done my best to distill a very complicated topic down to a few paragraphs. However, I realize I’m in way over my head here, and I’d be delighted to hear a more correct or complete explanation of the differences in the Comments.
I wanted to share a 3d rendering I’ve had in my inspiration file for awhile. I don’t know who did this, and the only identification I saved with the image is that it’s from a site called Renderings.com.
I love the attention to detail in this image. The lighting is excellent, and the lens flare effect (I think that’s what it’s called) is very effective. The modelling is virtually flawless. The fabrics on the sofa look very realistic to me, as does the stone floor.
In fact, if I didn’t tell you this was a rendering, you probably would have thought it was a photo. And that’s the holy grail for people like me who love photorealistic renderings. When someone tells me one of my images “looks just like a photograph,” I consider that the highest compliment!
I went back to the Renderings.com site to see if I could find out who created this rendering, but the site has changed quite a bit and I wasn’t able to find this particular image. The company specializes in renderings for high-end real estate marketing. There are many other great 3D images on their site of large apartment complexes, condos, and resorts, including some impressive animations. Check this one out:
What are some reasons for NOT using 3D images for your project?
There aren’t any.
You might think cost could be a reason. If so, then either:
For help with #1, read How to estimate the value of 3D visualization, A Picture is Worth a Thousand Words, Deep thoughts on 3D Biz, or 3D Rendering with Chief Architect. These posts from seasoned 3D designers and artists should make the cost to value ratio abundantly clear.
For help with #2, contact me at CastleView 3D, and if I’m not the right person for your project, I can refer you to one of the other professionals I know.
So you can see that there really are no valid reasons not to utilize 3D renderings and raytraces for your building, remodeling, or decorating project, unless you’re the type of person who enjoys big — and possibly unpleasant — surprises.
3D images are a valuable asset for improving communication, ultimately saving you time, money, AND sleepless nights!
I recently got a call from a friend. He and his wife are planning to put their house on the market soon, and are sprucing it up to get it ready to sell. It’s a beautiful, unique builder’s home, situated high on a hill with an incredible view. But the home was built in the 1980s, and some features have never been updated.
Their concern right now is the master bath. It’s a lovely space with skylights, lots of mirrors, and a garden tub. It has “good bones.” But the cabinets and countertop are mauve-colored laminate.
In case you don’t know what “mauve” is (and trust me, you are not the only one), consider this definition from Wikipedia: “Mauve (rhymes with “stove”) is a pale lavender-lilac color, one of many in the range of purples. Mauve is more grey and more blue than a pale tint of magenta would be… Sometimes mauve can be considered a dirty pink or a shade of purple. Mauve can also be described as pale violet.”
Well thanks, Wikipedia — that really clears things up.
I think “grayish pink” actually comes closest in this case. Mauve was a very popular color for decorating in the 1980s, particularly in business offices and dentist’s waiting rooms, and especially when combined with gray or teal. (Did I mention that this bathroom has a gray tub and sinks?) When my friends first bought the house, the same charming mauve laminate was also on all the kitchen cabinets and the dining room built-ins! Mauve overload! Luckily all of that was replaced early on.
My friends want to bring their bathroom into this millenium, but without spending a lot of money on it — just enough to make the bath a selling feature rather than a liability. So they asked for my assistance in envisioning what a coat of paint over the laminate, a new solid surface countertop with vessel sinks, and new carpeting could do for the space. CastleView 3D to the rescue!
After measuring the space and taking photos, I created a 3D model of their bath using Chief Architect. I added the vessel sinks and Corian countertop they wanted, “painted” the mauve laminate cabinets a neutral shade of ivory, and put in a new carpet. The raytraced images below show how much these small changes will improve and enhance their bath. Goodbye, mauve!
