#1.7 SideFX Houdini
SideFX Houdini is used for creating visual effects, animations, simulations, and 3D models in a variety of industries, including architecture and design. Its node-based structure allows for maximum flexibility and precision when adjusting objects, interactions, or effects. Using procedural modeling, one can create complex parametric models that can be easily modified in the future. The program offers broad capabilities for creating various types of simulations, including fluids, fire, smoke, and others.
SideFX Houdini integrates well with other software products, including Autodesk Maya and Cinema 4D. With Houdini, users can create tools for making interactive interfaces to control objects and effects in real time for other programs such as 3ds Max and Unreal Engine.
In architectural CGI, the program provides effective solutions for photorealistic 3D rendering.
#2. Rendering Engines
A render engine is a plugin for creating visual effects and rendering images. In a way, the engines “explain” to the primary software how to set the lighting, shadows, textures, materials, and other elements in a 3D scene. Some of the 3D modeling and visualization programs have their own built-in render engines.
Depending on the type of rendering engine, one can get different results in terms of quality, speed, and settings. Let’s take a closer look at the most popular 3D rendering engines.
#2.1 V-Ray
This is a widely used engine developed by the Chaos Group. It is utilized in architectural visualization, advertisements, the film industry, and many more. V-Ray boasts numerous advantages. First of all, it has algorithms for both CPU (processor-based) and GPU (graphics card-based) rendering. The plugin is known for its ability to produce exceptionally photorealistic results. What’s more, it offers tremendous opportunities for adjusting various parameters, which helps one greatly in transforming visions into 3D images with 100% precision. Plus, V-Ray offers a distributed rendering option that allows one to render different parts of a scene by different computers simultaneously. It has rich capabilities for balancing the speed and physical accuracy of the result. And finally, it has large collections of optimized materials and models.
As a plugin, V-Ray is integrated with many 3D visualization programs, such as 3ds Max, Maya, Cinema 4D, SketchUp, and others.
