3D Rendering Software

With the exponential progress in rendering technology, it has become mandatory to use the best representation techniques to showcase your design process. Over ten years ago, 3d rendering was a less explored field and only used by affluent clientele and established architectural firms.

But times have changed now, where even the most minor design, such as a room makeover, demands a high-quality realistic 3d representation not only by the clients but by designers themselves to understand and design the space better.

What is 3D Rendering Software?

To create stunning 3d renderings or visuals, you will need the help of software or a platform that will assist you in making 3d models and rendering them. The genesis of 3d architectural rendering starts with basic technical drawings made in CAD software such as ArchiCAD.

These CAD drawings are converted to 3d models. After the 3d models are produced, designers or 3d visualizers add textures, lights, and camera angles that give the model a realistic feel.

Finally, the rendering process is initiated where the rendering software, along with the hardware system, takes the parameters assigned and generates real rendered images of the model. These images can be viewed in different formats – individually or stitched together to direct an architectural walkthrough.

Types of 3D Rendering

There are three main types of rendering techniques that 3d rendering software partake in – surface, solid, and wireframe. You can choose the rendering you need based on your requirements.

1. Solid rendering

This rendering used geometric shapes like cylinders, cones, spheres, etc. You can combine all these shapes to make even more complex architectural forms.

2. Surface rendering

Surface rendering used a polygonal mesh made of millions of planar faces depending on the complexity of your model. This type of rendering is used to create panoramas.

3. Wireframe rendering

As the name suggests, the 3d model is made of lines and points intersecting with curves that trace the object’s shape.

Why Use 3D Rendering Software for Interior Design?

3d visualizations generated from various 3d rendering software can help you get your point across without needing additional explanation. Your clients will view your photorealistic renders and quickly understand what they will get and at what cost. You can add more human elements to your renders, like a throw on the sofa, and make your image more “lived-in” to give an edge and make it look more realistic.
