No matter, if it's architecture, gaming, advertising, or the product design industry, the demand for realistic visuals is higher than ever. Compared with physical prototyping, which is expensive and inflexible, realistic renders prove cost-effective alternatives and offer immersive experiences.
For instance, architects can visualize exteriors before starting construction and effectively communicate their vision to investors for constructive feedback. Similarly, 3D photorealistic rendering is bridging the imagination and reality gap in almost all industries. If you want to expand your knowledge regarding this technique, read this guide, which delves deeper into its dynamics.
Part 1. What is Photorealistic 3D Rendering?
It is considered a technique to generate lifelike images and animations using 3D rendering software and physically based virtual lights, materials, and camera angles. Simply put, photorealistic rendering is a digital technique that uses 3D models and rendering engines to generate an image that looks exactly like an actual photograph.
With the aim of mimicking photography, it creates high-resolution 3D images from detailed 3D models. Moreover, this technique involves precise adjustments of texture, lighting, and colors to develop as realistic a final image as possible. Additionally, it includes how light falls on an object, how it interacts with surfaces, and how the texture of an object changes.
Part 2. What is the Best Software for Photorealistic Rendering?
Upon knowing what photo realistic rendering means, it's time to explore some of the popular renderers which will let you craft photorealistic images.
1. Autodesk 3ds Max
This software is designed for 3D modeling, rendering, animation, and visualization to help you create stunning game environments and virtual reality experiences. In terms of 3D modeling, it facilitates retopology tools, smart extrude, modifier stack workflow, mesh, and surface modeling. Plus, it provides color management, a physical camera, an integrated Arnold renderer, a scene converter, and open shading language support to craft realistic images.
2. V-Ray
With the aim of creating photorealistic images and whatever you envision, it's another good photo realistic render software. It uses adaptive ray-tracing techniques and property scene intelligence to generate photorealistic imagery. Besides, it calculates the distribution of light and physical properties of material while utilizing cutting-edge Gaussian splats tech to create 3D environments. Furthermore, it can be integrated with other 3D software such as Maya, Blender, Nuke, and Sketchup.
3. Corona
For high-end architectural visualization, Corona is specifically designed with a simple setup for artists and powerful features. Through GPU rendering with vantage, it renders images within seconds while utilizing vantage live link and export capabilities. Plus, it gives LightMix to let you adjust the color and intensity of lights within the frame. Moreover, it provides extensive post-processing tools that eliminate the need to shift towards third-party software and enhance rendered images.
4. Blender
Blender is free and open-source 3D computer graphic software that comes with unbiased rendering path-tracer engines for ultra-realistic rendering. This renders photorealistic supports VR rendering, PBR shaders, HDR lighting, CPU & CPU rendering, and viewpoint preview. In addition, it has Cycles, which is a Blender's ray-traced-based production render engine. Cycles can accurately simulate varied shading, lighting, geometry, volumes, textures, cameras, and effects.
Part 3. How to Create Photorealistic Rendering?
Achieving a photorealistic 3D rendering demands a combination of precise processes, which are discussed ahead stepwise. Upon knowing clients' expectations, references, and basic sketches, you can begin your creative journey through the following process:
1. Modeling
Start by crafting a three-dimensional geometric model with the help of initial notes and sketches. In this context, you need to create an object's model while ignoring its physical properties for a while. You can utilize rotation, extrusion, rotation, and polygonal modeling techniques while getting help from software like Blender and 3ds Max.
2. Texturing
After building a realistic foundation, apply high-quality textures and realistic materials to the 3D model. For this purpose, you can create PBR (Physically Based Rendering) materials or get free or paid materials from online libraries. Besides, you need to properly unwrap UVs to avoid distortion in texture. It is advised to present some imperfections like glare and reflections; otherwise, the image will look too ideal and unrealistic.
3. Lighting
The next step is to add lighting, which is considered the most difficult stage because your assigned parameters will affect the entire perception of the model. Here, you need to precisely adjust the brightness level, temperature, light tone, shadow depth, and sharpness on the realistic render.
According to different situations, basic lighting setups (sun and sky for direct lighting) and HDRI lighting (rainy, cloudy, snowy) are applied to create a certain mood. Moreover, at this stage, you must focus on camera placements and decide what angle will be displayed to viewers.
4. Rendering
Most of the time, it is considered the final stage, where the 3D model is calculated with other parameters to craft a hyperrealistic image. During this process, 3D models acquire colors, realistic shadows, fine lines, and reflections based on the other objects in the scene, making every pixel of the image refined. For this, rendering engines perform huge calculations based on predefined algorithms, which makes the process time-consuming.
5. Post-Processing
If you find imperfections in the rendered image or it needs special effects, enter the post-processing stage. Here, photorealistic rendering results can be imported into software like Adobe Photoshop or After Effects. Afterward, you can adjust saturation, hue, contrast, background, or whatever is needed.
Pro Tips: Improve the 3D Photorealistic Rendering Efficiency
