8 Best Free Linux Renderers

One of the many strengths of Linux is its good range of open source software for artists, photographers, animators, and designers. With inexpensive hardware, free software, and a modicum of talent and inspiration, anyone can create professional-looking computer graphics.

Rendering is the process of generating an image from a model (or a collection of models, known as a scene file) using computer software. This entails the computer software to perform calculations to translate the scene from a mathematical approximation to a 2D image. To generate the image, the scene file contains objects in a defined language or data structure, containing geometry, lighting, shading, texture, and viewpoint. This data is processed by the rendering software to generate a raster image file or a digital image. There are three main computational techniques used by rendering software; scanline, raytracing, and radiosity. Rendering is a CPU-intensive process, so some software also makes use of the Graphics processing unit (GPU) to speed up the process. Images can be rendered by a single computer or with a network of computers that work on a different part of the image.
