Dive into the basics of 3D rendering before assisting for its services.

The higher level picture of 3D rendering and 3D visualization is simple – it infuses life in images.

A lot of effort goes into architectural visualization, selecting the best type of 3D modeling for a use case and developing the final product which must be phenomenal to justify the effort. The effort in 3D rendering can only be optimized when one knows the basics and difference between the types of rendering available.


3D rendering found its use in such varied forms that it has evolved as a new branch of animation. Being a deeper part of Computer Aided Design, it assists in better visualization and designing. Reasons behind 3D Modeling becoming popular are quite evident from the results. It holds the potential of making a product design efficient, less time-consuming and flawless.

It has found its application in movies, manufacturing, architecture science, healthcare, fashion industry and more. Each specific application of 3D rendering works on some basic set of principle. 3D modeling process assists technology to transform art into reality.

Different techniques of 3D Rendering

The techniques used for 3D rendering are entirely a designer’s choice but the individual must pay a serious thought of picking up the right technique. Knowing the end-result needs, time or precision, helps designers make the best choice. Each technique has its benefits and is of primal choice for certain set of results.

  1. Scanline

    If time is short and rendering needs to be precise, Scanline technique is the most suitable option.  The acceleration with which Scanline rendering works is perfect for both practical and real-time needs. It goes beyond the simple polygon or pixel level rendering. It renders the entire scene as a set of horizontal lines. As an algorithm for visible surface determination, each polygon is rendered on the y-axis coordinates and then each scan line is determined. The Scanlinemakes the entire process of 3D rendering fast backed with quality results; making it the perfect technique for real-time needs.

  2. Raytracing

    Are you in a time frame that supports refined extensive results? Raytracing technique is most suitable for your job. Working at pixel level of 3D modeling, the rays of light are traced back to the object from the camera and each pixel placement, texture, hue, depth and more elements are defined in an algorithm. These pixel level images are called raster images. Multiple angles at the pixel level of the virtual object are overlapped to develop a final image which comes out to be astounding, to say the least. To sum up, raytracing is a time-consuming technique but offers super refined results nonetheless.

  3. Radiosity

    Closely related to ray tracing, Radiosity offers an expedited solution for calculating the light propagation of a scene. Basically, Radiosity technique focuses on the 3D rendering of product surfaces. The algorithm is developed to store illumination values of each surface of the object. Today, radiosity rendering works on stochastic methods, GalerkinRadiosity that simulates the photon propagation.It is the most suitable way to render real-life colors to the objects and also handle the appropriate shadow development.

Differentiating between the basics of Rendering on the basis of time

A 3D rendering technique transforms the lines and points of a simple 3D image and infuses life into them. How it does that varies as per the use case requirement. The rendering tool works on the mathematical relationships of these images and converts them into lifelike images.

The mathematical representation works to render texture, shape, colors, shadows and more to the image, making it stand apart from the regular 3D image. Before picking up the rendering technique one needs to understand its basics.

  1. Real-Time Rendering

    Real-time rendering is used when instantaneous results are required. The gaming industry has been highly benefited by this. Using the high computational power graphics hardware, rendering can translate up to 120 frames per second which is great for gaming.Real-time rendering has delivered very realistic results so far. The real-time computational power of the CPUs is saved by using some pre-computed images or template images.

  2. Offline Rendering

    Offline rendering is appropriate for tasks where wide time-frames are available. Multi-core CPUs work together to deliver excellent results. Animation movies need the highest quality of 3D rendering as the results matter. Multiple frames need to be rendered with the highest quality for the end result to be amazing.


3D rendering has benefited the gaming and filmmaking industry with its high level of control to develop artistic images of visualized ideas. The basics of 3D rendering give a designer deep insight of what techniques and software must be chosen to deliver exceptional results within the desired timeframes.
