Physically Based Rendering

Brief Definition

Physically Based Rendering The use of Physically Based Renderers (PBR) always includes elements and simulation that mirror real physical processes.

So, basically, "physically based" means an implementation of natural physical models that are valid outside rendering techniques. It is based on observable physical laws and principles according to which the light propagates in our world. When it comes to components or materials, each of them has its own characteristics that affect the scattering and reflection of light thereon.

PBR is also known as an unbiased rendering method that does not introduce biases and distortions in the evaluation of lighting. Thanks to this ability, it is often used to generate a pattern image, which is compared with other visualization methods.

In short, game development community now has a standard method that implements actual material quality and description and contributes a natural lightening system. It allows creating a materially accurate photographic image.

Why Physically Based Rendering

Modern game today cannot be made without physically based rendering. PBR allows designers to create a beautiful picture and add efficiency to a game by using small means. In other words, such rendering makes the game attractive and less resource-intensive. PBR actually reduces the number of polygons and creates the volume of a model using the lighting.

The main diversity between non-physically based and physically based visualization is that the last resemble the world’s environment. Once the model is placed, and the lightening structure is set, a person can immediately receive a comprehensive volumetric item.

Benefits of PBR

First of all, it should be stressed that it’s not enough to know the theoretical part of a physically based rendering to be able to provide qualified services. 3D-Ace is a team of experts with many years of experience in PBR and a large number of successfully implemented projects.

3D-Ace is a professional CG studio that can contribute to your project by production of photorealistic physically-based renders that reduce the production expense in comparison with other rendering techniques.

Since 2009, we've developed numerous projects in 2D and 3D, including models and props for Unity and Unreal Engine as well as AR/VR/MR-ready 3D models. Contact us!
