MiniLight is described as 'minimal global illumination renderer. It is primarily an exercise in simplicity. But that makes it a good base and benchmark (in some sense) for development and experimentation. And it just might be the neatest renderer around (on average, about 650 lines)' and is an app in the Development category. There are more than 25 alternatives to MiniLight for a variety of platforms, including Windows, Mac, Linux, Autodesk 3ds Max and Sketchup. The best alternative is Adobe Dimension. It's not free, so if you're looking for a free alternative, you could try LuxCoreRender or POV-Ray. Other great apps like MiniLight are Keyshot (Paid), V-Ray (Paid), appleseed (Free, Open Source) and RenderMan (Free Personal).
Arion is the hybrid-accelerated and physically-based light simulator developed by RandomControl. It inherits all our expertise in light simulation and makes it run on steroids, thanks to our very unique approach to massive CPU+GPU+LAN computation.
As an interactive, photorealistic renderer, Shaderlight redefines traditional rendering workflows. Simple to learn and easy to use, it features ‘progressive’ rendering that lets you see your image develop as you work so you can visualize your ideas in no time.
PhotoView 360 is the new visualization and rendering solution from Solidworks. Its a highly interactive environment for viewing your designs as well as for creating photorealistic renderings that you can use to showcase your designs.
