What is 3D Rendering Software?

3D Design and 3D modeling and CAD software like AUTOCAD and AUTODESK help interior designers create their space in 2D and 3D. These are saved in various file formats before they are processed to get the final architectural rendering that resembles the real world. 3D Rendering is the final step of the design process – whether you are an interior designer, architect, or a general CAD user. 3D Renders are the bread and butter of any design professional and so it is of utmost importance that interior designers and architects choose the best 3D rendering software for their designs and projects.

If you’re an architect or interior designer, you’ve probably worked with 3D rendering services, and rendering tools to get high-quality images of your designs. But this means you probably also know about the challenges with many of the 3D rendering software on the market today.

That’s why we’re going to help you choose a better 3D rendering software, so you can create amazing 3D renders without hassles like:

  • Extremely low speeds with most rendering solutions
  • Heavy CPU and GPU usage
  • Poorly-defined textures
  • Expensive licenses
  • The complex user interface of BIM 
  • And more.

But first, we’ll review a few key pieces of information that are important to know when it comes to 3D rendering.

3D rendering software

What is 3D Rendering?

A 3D render is essentially a 3-dimensional image data stored inside a computer. 3D rendering is usually used to create realistic two-dimensional images of architecture or interior designs made on design software before any real-life work has been done.

To correctly depict a photorealistic 3D render, you need to use special rendering engine-based software that can understand and capture the 3D elements in your scene. You can also add specific lighting, texture, or even motion blur effects to help make the rendered image even more realistic.

Types of 3D Rendering

There are typically three methods of creating 3D renders – wireframe, surface, and solid. Each method constructs the 3D renders in a different way, and the editing methods differ between each type. Therefore, it is always best to stick to any one style of rendering and not combine them.

A wireframe model creates a skeletal description of a 3D object. It doesn’t contain any surfaces – it consists only of points and lines joined together by curves, which cover the shape of the object. Wireframe models can be created by positioning planar objects anywhere in a three-dimensional space. There are some three-dimensional wireframe objects that have continuous linetypes, meaning the 3D rendering artist needs to draw and position every object separately independently. That is the reason wireframe rendering usually takes the longest time to complete.

Surface modeling is a more elegant method of creating 3D renders. This process defines both the surfaces and the edges of a three-dimensional object, which can then be rendered into a panorama, 360 degree & virtual reality, and more. Although this is distinct from the wireframe process, it is similar in that it also makes use of a mesh. This mesh is a polygonal mesh with planar faces, which limits the accuracy of the depiction of curvilinear surfaces.

Finally, solid modeling is the fastest and convenient method for 3D rendering. This process starts by using the elementary geometric shapes in three dimensions – like boxes, cones, cylinders, spheres, wedges, and concentric circles in donut shapes. Each of these shapes can then be added and subtracted from one another to produce more complicated shapes and architecture. Some experts can up their game by dragging a 2D object on a fixed path or make it rotate around a fixed axis. You can also create solids by sweeping a 2D object along a path or revolving it about an axis.
