Rendering is the final step in the 3D pipeline, generates 2D image or animation from a 3D scene. These are steps of determining how light interacts with objects in the scene to look realistic from surface color to shadows dropping.
Types of Rendering
Real-time Rendering: Used in applications such as video games and simulations where the image being shown updates as soon as one of several factors changes (the rotation of an object or camera). But, as an inevitable trade-off speed comes at the sacrifice of realistic input so it sidelined.
Offline Rendering: films, as well as some high-quality animations — the offline rendering produces very realistic picture but can sometimes takes hours or days to complete on a single machine. Utilize a render farm like ours for better performance!
How Rendering Works
Blender rendering engines (such as Cycles or Eevee) work by simulating light. They model the way light moves from sources, reflects off surfaces, and merges with the materials to produce realistic lighting, shadows, and textures.
Global Illumination (GI): A tech used from in rendering to imitate how light bounces off surfaces giving you softly, realistic shadows and indirect lighting.
Ray Tracing: A rendering technique to deliver realistic results by tracking the path of light rays on a per-pixel basis for true reflections, refractions, and shadows.
Advantage of Rendering in Design and Animation
Realism: Rendering can produce photorealistic scenes, thus it is an optimal solution for architecture, product visualization or film.
These enable visualization and designers can experiment with materials, lighting, and environments to visualize their designs long before they are built.
