• Bitmaps are always orientated horizontally and vertically.
• Vector based applications such as Corel Draw and Adobe Illustrator treat images as
collections of vectors and shapes.
• Drawing in 3D adds a third axis to the X and Y-axis used in 2D. The Z-axis allows a third
dimension, to create objects with a 3-dimensional thickness, or shape.
• Rendering is one of the major sub-topics of 3D computer graphics, and in practice always
connected to the others.

• Natural light is used, augmented or even combated by using a number of different
techniques.

• Online tools are code driven and full of features to help someone build the perfect colour
scheme.
• The Macintosh PICT (Macintosh Picture) format is associated with applications on the
Macintosh and is one of the best supported formats on that platform.
• Microsoft Windows Imaging (WIM) files are compressed packages that contain a number
of related files. The format of a WIM file is optimized for maximum compression with LZX,
for fast compression with XPRESS, or uncompressed.
