Simple Normal Mapper

Simple Normal Mapper is intended to assist 3D computer graphicians in applying the normal mapping technique. Widely used in video games, this method can add more details and depth to a 2D image by altering the lighting in level oscillations, creating the false effect of a 3D picture.

The application is capable of processing common image file types, namely PNG, JPEG and JPG and save the generated normal map in the same formats. Its forthright approach makes it very easy to use, making us believe that it is mostly intended for beginner graphic designers.

One of its main advantages is that it enables you to view the input and the output within the same window, for comparison purposes. Along with the adjustable zoom level, this helps you preview the result and make the necessary modifications before saving the file to your computer.

The sampling radius and the height amplitude are customizable parameters whose values significantly affect the output appearance.

As mentioned above, the application is very easy to use, only requiring you to open the input file, modify the processing parameters and press the 'Render' button to view the outcome. All your actions are displayed in a dedicated 'Log' section.

On the downside, drag and drop is not supported, so you must load a file the old fashion way, using the 'Open new image' option in the 'File' menu. Another inconvenient is that you cannot process more than one picture at a time.

While it could use some enhancements, Simple Normal Mapper can prove useful to anyone who wants to normal map a 2D image. With live previewing and adjustable rendering parameters, it is worth having within reach for image processing.
