Let\u2019s begin with a question: what is the end goal of photoreal computer-generated imagery (CGI)? To create imagery so lifelike you almost can\u2019t distinguish it from an actual photograph. An increasing number of companies and design agencies of all sizes now rely on CGI, more specifically 3D rendering services<\/a>, to communicate ideas or concepts with stakeholders, and eventually market the final products to consumers at large. This doesn\u2019t mean conventional photography has been completely abandoned. Still, it\u2019s safe to say that the vast majority of product images you see today are computer-generated, or at least a combination of CGI and real photographs.<\/p>

Are all CGI photorealistic? Not always. It all depends on the style you want. Some digital artists excel at generating a product visualization identical to the actual physical object, while others specialize in stylized imagery for cinematic and dramatic flair. At Cad Crowd, you\u2019ll find professionals capable of both approaches, giving you the best blend of photorealism and artistic touches.<\/p>

Hallmarks of great product visualizations<\/h2>

Why not just take some photographs, then? Seems like a no-brainer question considering how simple it is to fire up the camera and take some product snapshots. But you must remember that to produce any product image at all, photography needs the product to exist in the first place. In an NPD (New Product Development) project<\/a> <\/strong>where the design is yet to exist, CGI has the clear advantage.<\/p>

\u200bFlexibility is another major advantage of CGI services, as 3D rendering offers the freedom to visualize otherwise photographically impossible cutaways, exploded component views, the inner mechanism of a product, microscopic close-ups, etc. At the same time, thanks to the \u201cvirtual\u201d nature of 3D rendering, you can modify and reuse the image without having to rely on the physical product. For instance, if you plan to offer a product in dozens or more color combinations or variants, a digital artist can get them all done much faster than even a professional photographer.<\/p>

\u200bA marketing head start is also an upper hand you can\u2019t take for granted. The ability to market a product (because you have a photorealistic visualization of it already made) before the actual launch date or even before the mass-manufacturing process begins gives you a massive head start to gain a real competitive advantage. And if you\u2019re confident enough about the product quality at this point, no one is stopping you from taking pre-orders or crowdfunded investments.<\/p>

\u200bCad Crowd gives you easy access to some of the world\u2019s most talented CGI professionals and digital artists<\/a> with the know-how and the experience in 3D product renderings of any category, whether electronics, mechanical, medical, or industrial, or any combination of those. Truly effective photorealistic visualizations aren\u2019t the stuff of amateurs. <\/p>

It takes an in-depth understanding of how 3D modeling, the physics of light behaviors, familiarity with surface textures, and, yes, camerawork, among others. It\u2019s a specialized trade best left to professionals armed with insights, artistic touches, and certainly the right tools to bring about and put together these ingredients to craft top-quality product visualizations.<\/p>

Precise 3D modeling<\/h3>

Rendering doesn\u2019t happen without 3D modeling. Every design must first be 3D modeled using CAD software. However, not every visualization project starts from scratch. For example, if the product already exists and you want a CGI version of it, we can build the model based on photographs using the photogrammetry technique or a 3D scanner to generate the basic shape and layout. <\/p>

The resulting model from either method is geometrically accurate, but it just doesn\u2019t have enough detail (yet) for photorealistic rendering. It still needs some refinements in materials, textures, and colors to make it more presentable. Keep in mind that scanning and photogrammetry only cover the product’s surface area. In case the rendering has to showcase the inner mechanism, such as in an exploded view format, disassembly might be required.<\/p>

\u200bWhether we start with an existing product or a mere concept from a napkin sketch, the bulk of the 3D modeling work services<\/a> is done using advanced tools like Autodesk Fusion, SolidWorks, Blender, Rhinoceros 3D, and Shapr3D, to name a few. Software choice is indeed important, although the professional sitting in front of the computer still makes all the difference between top-notch accurate models and poorly built assets. And the more accurate and detailed the 3D models are, the better the final 3D rendering will be.<\/p>

Material details and texture mapping<\/h3>

On top of the bare 3D model of a product, there need to be material details and surface properties. Your product, or at least its outer body, might be made of wood, plastic, metal or metal alloy, leather, glass, etc. Each material comes with its own set of characteristics, which ultimately affects the degree of realism during the latter stages of the process.<\/p>

For instance, polished and brushed stainless steel have different degrees of reflectiveness and shine; when exposed to light in the rendering phase, the materials generate unique lighting effects and create distinct visuals. The sense of photorealism is also heavily affected by the lighting configuration itself, but this is to be discussed later.<\/p>

\u200bStill on the subject of accurate geometry, \u201chard edges\u201d deserve specific attention here. With the exception of parts\/components that are actually intended to be sharp, like glass corners or the actual edge of a knife or razor, most objects in the real world have no hard edge. A lot of products tend to avoid such a thing simply because it makes an object uncomfortable to hold and use at best, and is a safety hazard at worst. When the geometry drawing seems to suggest that an object comes with hard edges, like the corners of a square, they\u2019re usually rounded off.<\/p>

If you take a close look at the edge of a tabletop, it\u2019s likely beveled for comfort. Not even a speed square has a perfect 90-degree angle anywhere on it. In 3D modeling services<\/a>, it\u2019s easy to fall into the trap of making anything geometrically precise. No one is against accuracy, although in this particular case, the precision can backfire. Softening hard edges is the right thing to do, not only because they\u2019re not recommended in manufacturing, but beveled edges (no matter how unnoticeable they may seem) do make the rendering more realistic.<\/p>

\u200bOn top of the material, there\u2019s another defining layer in the form of texture. We use only high-resolution textures and shades to best reproduce the real-world look and feel of an object\u2019s surface properties. As briefly mentioned earlier, the same material can have different textures. Stainless steel, or metal in general, isn\u2019t the only material with this peculiarity. Plastic can be clear, matte, or perhaps colored; leathers might be smooth or coarse; woods come with different grain patterns, and so forth. We apply texture to the material surface using either a texture mapping technique, which basically utilizes a projection of a texture onto the surface of the 3D model, or digital painting.<\/p>

\u200bRemember that 3D modeling isn\u2019t just for the product. The environments must be modeled, too. Say your product is a bottle opener. You have the option to display the object as a stand-alone visualization against a plain backdrop, or put it in a scene along with other accompanying objects, for example in a kitchen setting. The former is excellent if you want to showcase the product in a close-up view, whereas the latter (commonly referred to as lifestyle rendering<\/em>) delivers a better realism effect. A product placed in its natural environment looks more believable.<\/p>

Lights and shadows<\/h3>

Now come the most important rendering factors of them all: lights and shadows. Yes, the 3D models are clearly visible on the computer screen already, but they\u2019re not exactly photorealistic, aren\u2019t they? The problem is, there can be thousands of different lighting setups, and an even bigger problem is that most of them won\u2019t deliver the desired realism effects. One of the great misconceptions in 3D rendering services<\/a> <\/strong>is that more lighting creates better visualization. You can\u2019t be any more wrong than that. Let\u2019s refer back to our previous example of a bottle opener. First, we need to consider the rendering scene you need. A bottle opener can be displayed in an indoor space (a kitchen, living room, a tent) or an outdoor area (the backyard, the beach, the back of a pickup truck). Either way, the product won\u2019t look out of place so long as the lighting is set to complement the environment.<\/p>

\u200bAn indoor space often makes use of artificial lighting such as an overhead lamp or a portable rechargeable LED emergency lantern, especially if it\u2019s placed in a tent. An overhead lamp can be in the form of a chandelier, ceiling-mounted, or pendant light. A portable lantern also offers models with different brightness levels and color temperatures. It\u2019s worth mentioning that an indoor space can have windows to let natural light sources come through. As for the outdoor area, your main source of light is the sun, but the intensity varies depending on time of day, season, and weather. You wouldn\u2019t want a product visualization made for sunset and sunrise to look the same. The point is, you have loads of options to do the lighting setup.<\/p>

\u200bShadows are just as important and complex. They define contrast and depth, without which the realism effect suffers a great deal. Shadows must be the direct consequence of the presence of light. However, different light sources and setups should not and cannot cast the same shadows. The intensity, direction, reflection, absorption, and refraction of light as they hit an object determine the nature of the shadows. <\/p>

For example, a spotlight hitting directly at an object will cast sharp, defined shadows; on the contrary, if the object is placed next to a glass window that merely allows sunlight to come through from the outside, its shadows are typically softer and diffused. The window size and whether the glass is tinted further increase the complexity. Adding to the intricacy are the object\u2019s materials and surface textures that play a role in how light behaves as it bounces off them.<\/p>

\u200bOne might argue that shadows are nothing but byproducts of lighting. It does hold some truth in the sense that every light casts shadows. That said, in the world of 3D rendering at least, shadows actually enrich the scene and bring forth the perception of space. They might look like dark blotches under and behind an object, but nonetheless integral elements of photorealism design project services<\/a>. We can\u2019t have light without shadows, but it also doesn\u2019t mean we can\u2019t manipulate them to work to the benefit of the visualization.<\/p>

\"photorealistic-cgi-product-rendering-best-practices\"<\/figure>

\u200bThere\u2019s no denying that different light sources, types, and positioning result in a large variation of shadow quality. They\u2019re among the hallmarks of the nuances and complexities of real-world settings. The digital artists at Cad Crowd understand the challenges as well as the importance of dealing with light setups in 3D rendering applications. At the same time, we\u2019ve been honed by years of experience in product design CGI to imitate and reproduce the physics of how light and shadows intertwine as features in photorealistic rendering.<\/p>

Key, fill, and rim<\/h3>

Nothing screams top-quality product 3D renderings and visualization services<\/a> better than true-to-life lighting. We might use a three-light studio setup to simulate the human\u2019s natural perception of an object, in this case your product. Such a setup allows us to mimic a large variety of light sources and configurations in a realistic fashion to the point where it tricks the viewers\u2019 minds into thinking that they\u2019re looking at an actual photograph. As the name suggests, the setup consists of three light sources: key, fill, and rim (backlight).<\/p>
