Card Bevelling processes

3D surface

Bevelling is one of the finishing processes done on images. You can apply card beveling to add depth to your images. The image produced has a similar shape to a bevelled wooden, plastic or metallic edge. It produces 3 D shapes of objects. When there are consistent shadows and lights, the object produced will appear to be having volume.

What is the effect produced by the bevel effect?

Typically, a bevel filter used in performing the following steps.

  • Determining the drawn object’s outline
  • Extruding 2D objects to produce a 3D dimensional object
  • Bevelling the edges of 3D objects
  • Illuminating 3D objects to obtain the locations of shadows and highlights

Steps followed in the bevelling processes

Step 1: This step is very easy. In this step, the object’s shape is determined directly by the transparency or the images channel. The image mask is used where the transparency is inadequate or available.

Step 2: In this step, a 3D object is created by assigning a height inside the shape. Bevelling of the edges is done once the 3 D is produced. The edges of the images are cut to remove the corners. It can also have a complex shape such as rounded. The height of the 3D object is configurable.

Step 3: This is the last step. This is where the lighting effects are computed on the 3D shape produced. This process is not hard but involves many variables. The result depends on the lighting source used, the viewer’s position and the material used in making the 3D object. A typical bevel uses a single lighting source (preferably white colour). This colour is helpful in keeping the colours of the beveled images close to the actual or original object.

To improve the results of the bevel, you should observe the following points

  • Use bevel sparingly: Just as the saying goes, “Too much of something is poisonous,” you should avoid overusing bevel. Doing this might distract the viewer’s attention.
  • Use bevel consistently: having inconsistent bevelled objects can confuse your brain. Any object should be used consistently. This should apply even you have multiple images that are undergoing the same process.
  • Combining bevel with shadows:This process is known for producing a 3D aspect similar to that of shadows. A shadow should be added to the object when there is light shining is being used. It is done to reinforce the 3D feeling as well as helping the brain in positioning the different objects in space.
