2. Modeling Approach

Blender primarily utilizes a polygonal modeling approach, where objects are made up of vertices, edges, and faces. This method is excellent for creating organic and freeform shapes, making it highly effective for character modeling, digital sculptures, and concept art. Additionally, Blender includes sculpting tools that allow artists to manipulate meshes in a way similar to working with clay. While it does not support NURBS modeling natively, its subdivision modeling techniques make it possible to create smooth and detailed objects.

Rhino, in contrast, is built around NURBS (Non-Uniform Rational B-Splines), which allows for highly precise and mathematically accurate modeling. NURBS is essential for designing objects that require exact measurements, such as engineering components, furniture, and architectural elements. Unlike polygonal modeling, which is more approximation-based, NURBS models ensure smooth curves and surfaces without relying on subdivided polygons. This makes Rhino ideal for industries where precision is a necessity rather than an option.

3. Rendering & Visualization

Blender comes equipped with two powerful rendering engines: Cycles and Eevee. Cycles is a physically based path-tracing engine that delivers highly realistic renders, making it an excellent choice for architectural visualization, product design, and cinematic scenes. Eevee, on the other hand, is a real-time render engine that allows users to see their scenes with realistic lighting and shadows instantly, making it ideal for animations and game asset previews. Both rendering engines are highly customizable and support advanced features like ray tracing, global illumination, and volumetrics.

Rhino does not have a built-in real-time rendering engine like Blender’s Eevee, but it supports a variety of third-party renderers such as V-Ray, KeyShot, and Enscape. These integrations allow Rhino users to create stunning photorealistic images for architectural presentations, interior design, and product visualization. Since Rhino is commonly used in CAD workflows, rendering in Rhino is often done through external plugins that offer more flexibility in material application and lighting.

4. Parametric & Procedural Modeling

Blender has recently introduced Geometry Nodes, a system that enables procedural modeling, allowing users to create highly customizable and non-destructive workflows. This makes it a powerful tool for generative design, where objects can be created and modified using mathematical inputs. While Blender does not have a traditional parametric modeling system, add-ons such as Sverchok help bridge the gap by offering parametric capabilities similar to Rhino’s Grasshopper.

Rhino, however, is widely recognized for its Grasshopper plugin, which is one of the most advanced parametric modeling tools available. Grasshopper allows users to design complex structures, algorithmic patterns, and responsive architectural forms without manually modeling every component. The ability to control models through parameters makes it an invaluable tool in computational design, particularly in architecture and engineering.
