Quick guide to recognizing pitfalls of realistic 3D visualization
Implementing 3D representations is useful in various fields, for example, to promote products under marketing strategies, and of course, to attract customers and achieve sales in the field of real estate.
But even more important than implementing 3D renderings, is implementing it well. Using a flawless photorealistic 3D visualization is essential to get the response you expect from your audiences.
For example, to show a property to potential buyers outside your city, you have probably used photographs at some time. But organizing photo sessions require too much time and effort, and the results do not provide all the sensations or awaken the emotions necessary for your client to fall in love with the property. Even the perspective of a photograph can make you feel that something is not quite right. Those margins of error can be eliminated by professionally implementing 3D visualization.
You can do it! To help you, we share a list of common mistakes made by newbies in the use of 3D visualization, which can help you prevent and avoid them:
- Floaters and Intersections: One of the first bugs that immediately catches your eye is objects that intersect and float. Even untrained eyes can tell if something isn't in the right place, and 3D objects floating in the air are more than obvious.
- Perspective Distortion: Setting a wrong focal length leads to perspective distortion in 3D viewing. Also, this is a classic rookie mistake. The main consequence of this error is the display of bent and twisted objects that do not look as they normally do in real life. The fisheye effect in 3D renderings is the first indicator of perspective distortion. To avoid this, it is important to know a simple rule: the focal length cannot be less than 24mm.
- Actual scale mismatch: Novice 3D visualizers often place objects in a scene without paying attention to the manufacturers' dimensions. As a result, they get small chairs with huge table lamps or armchairs stretched out to the size of a living room rug. The solution to this problem is quite easy, and it is based on the standard manufacturing dimensions of the drawings. The second step is to compare the product parameters to other objects in the 3D rendering scene and make sure they all match the actual sizes.
- Low-quality 3D models: The easiest way to screw up 3D product renderings is to use low-quality models. There are many 3D objects available online, so it is important to choose only the best ones. Inexperienced creators can recognize them by some essential properties, as high-quality 3D models have impeccable geometry, smooth surfaces, and carefully crafted details.
- Poor textures: Low texture resolution is another reason why 3D renderings fail. Blurred patterns and unrecognizable details on object surfaces identify this error. Low-quality textures don't allow your customers to recognize what kind of materials the displayed objects were made from, plus it makes all surfaces look unnatural and flat.
- Unnatural light intensity: 3D renderings can be marred by too much or too little light effects, or improper use of the same effects based on light sources. To avoid this, it is important to give a different level of brightness to all light sources to differentiate the main and secondary lighting. Also, remember that the shadows should fall in the opposite direction from the main light, which is the same for all elements in each scene. Objects that are closer to the light source have to be brighter than those that are farther away.
