3D rendering is the final stage of creating a 3D image. It involves forming a photorealistic image or a non-photorealistic image out of a 3D model. This process comes after 3D modeling which entails the use of software to create a mathematical representation of a product. The model formed is therefore in the form of connected shapes. Rendering then provides this model with physical properties such as texture; thus giving a realistic image of how it will look like a real-life object. This image can be viewed properly through a 360 product viewer.
3D rendering, like modeling, works with the use of the software. Different software programs are used on different models and tasks. For example, creating video games and animations employ the use of applications or software programs that are more powerful and complex than the ones used by architects. Rendering artists should explore the various rendering applications available to find the most suitable one for their work. 3D rendering programs are designed to interface with modeling programs hence making 3D object creation easier. VRAY is one of the most used rendering software used to create realistic 3D objects by use of ultra-realistic light. Some of the most used software in rendering include Hypershot, Octane render and Keyshot.
Uses of 3D Rendering.
Architecture: 3D rendering applies to a variety of fields. In architecture, it allows architects to express themselves by showing in detail what they have to offer.
Interior design: Interior design is about experimenting with different things until you find what works. Using graphic design and 3D rendering is an effective and cheap way to experiment.
Manufacturing industry: To give consumers an idea and glimpse of future products, manufacturers use 3D models. 3D rendering makes these models look like the real product, and therefore buyers can have a clear idea of what they are buying.
3D rendering also applies in areas such as marketing and advertising and video gaming.
Steps in Rendering
3D rendering occurs in the following stages.
- Understand your task.
This is the most crucial part of 3D creation. Ensure that you clearly understand what your client needs. Use the provided sketches and pictures with different camera angles to guide you.
- Modeling
As discussed earlier, rendering requires models. Find the most effective software that will help you create your model. Pay attention to every detail.
- Apply texture
Texture makes digital models look real. Ensure that you pick the most appropriate texture type and settings for your model.
- Lighting Techniques.
In the real world, lighting plays a crucial role in photography and how photographs look. This same concept applies to the digital world. There are various lighting techniques available such as spotlight, Omni light, and ambient light. Pick one that best suits your task.
- Revision.
The first draft is not always perfect. Go through your model again making the necessary adjustments on texture, lighting, and scene until you are satisfied with the results. This stage will also allow you to make any necessary changes.
In conclusion, 3D rendering is not only an essential part of graphic design; it is also the fun and exciting part that gives life to digital creations.
