CAD Rendering Services are the go-to organization for near reality images of your product. We use CAD software to create and produce digital images of products and designs that are as “close-to-reality” as the finished product.

CAD Rendering Services creates a realistic digital representation of products that can be used to engage customers via Amazon, eBay, Shopify etc. Picture-realistic images are produced from CAD files that have been converted to a 2D or 3D-Model. They are then edited and finessed to provide an artistic vision of the final product. If you are interested, contact us.

The image produced can be either photo-realistic or non-photo-realistic and is called a “render”. The term “rendering” refers to the artistic process of generating a photo-realistic image from a 2D or 3D model through CAD Rendering Software Applications.


CAD rendering services are used in many industries such as Cinematography, Architecture, Video Gaming, Simulation Programmes and TV visual effects, as well as being used by Biomedical Professionals, Engineering Illustrators, Structural Engineers, and Manufacturing Industries.


Features are what characterizes and distinguishes a rendered image and relate to algorithms and techniques of the rendered image.
Some of the features and their definitions are:

  • Non-Photo-realistic Rendering: This is when an image is rendered in an artistic style and is made to look like it was drawn or painted.
  • Reflection: The image looks as though it is reflected in the mirror.
  • Bump Mapping: This is a method of simulation for bumpiness on the surfaces.
  • Texture Mapping: This involves the application of detail onto surfaces.
  • Shadows: Shadows are a special effect whereby light is added and its effect over objects projected.
  • Soft Shadows: This is almost similar in nature to Shadows. However, the darkness is not total because there is only a partial obstruction or obscuring of the light.
  • Fogging: Also known as a participating medium. It refers to how the brightness of light is lessened or becomes less intense, distinct, and bright when it passes through an atmosphere or air that is not clear.
  • Shading: This refers to the varieties of colour and brightness in response to light
  • Translucency: Refers to how light is transmitted in a highly shattered form through solidified objects
  • Transparency: This also refers to how light is transmitted through solidified objects. The transmission of light here is, however, in a sharp form. Transparency can pertain to optics, graphics, or opacity.
  • Refraction: How light bends in relation to transparency
  • Diffraction: The bending and interference of light moving through an object.
  • Motion Blur: With this feature, objects or the rendered image are made to appear blurry. This blurred effect is a result of high-speed motion. It can also be as a result of the camera settings.
  • Depth of Field: This feature also makes images and objects blur. The camera is focused on the object but cannot focus on the background when there is a significant distance between them.
  • Indirect Illumination: Alternatively known as global illumination. This is when the reflection of other surfaces lightens and illuminates a second surface. The illumination here is not direct.
  • Caustics: This is also a type of indirect illumination: It is when a highlight of an object is as a result of the reflection off another shiny and bright object or the focus of light via another object that is transparent.

Photorealistic Rendering Technique

There are various rendering techniques that can be employed individually or combined depending on the required end result. It is a time-consuming process for CAD software applications to trace every photon – every particle of light.

Therefore, various techniques have been developed that will speed up the process and will still efficiently provide the same end result. These techniques are Scan Line Rendering or Rasterization, Ray Casting, Ray Tracing, and Radiosity.

  • Rasterization: 

    Scan-line rendering does not use advanced optical effects and geometrically translates objects to an image plane. It essentially maps objects from a scene and does not impose a way to handle the colour, texture, or lighting.

  • Ray Casting: 

    Based on the geometry and a few optical effects, it takes in the scene from an independent angle and calculates what that scene or image requires. It uses the Monte-Carlo technique (the use of randomness to produce results {add link here to something like Wikipedia) so as to reduce inaccuracies.

  • Ray Tracing: 

    This technique is an almost similar mode of operation to Ray Casting. It also uses the Monte-Carlo Technique and a more advanced level of optical simulation. It produces a more realistic effect at a greater speed.

  • Radiosity: 

    This technique calculates the movement of light as it moves from the source and illuminates the surfaces. It is not usually recognized as an independent type of technology because the surfaces the light illuminates are rendered from a combination of other CAD Rendering Techniques.

CAD Rendering Service works collaboratively with other techniques to give you enhanced 2D or 3D designs. Geometric Optics and Visual Perception are two such techniques.
