Difference between 2D and 3D design.

2D design refers to creating images or graphics that exist only in two dimensions: height and width. This includes drawings, paintings, and digital graphics such as icons, logos, and user interface designs. In 2D design, the artist or designer creates the illusion of depth and perspective using techniques such as shading, colors, and gradients.

On the other hand, 3D design involves creating objects that have height, width, and depth. These objects can be viewed from any angle, and they are often used in video games, movies, and virtual reality experiences. 3D design typically involves creating models using specialized software that allows the designer to manipulate the object in a virtual space. The process may also involve adding texture, color, and lighting effects to create a realistic-looking 3D object.

The key difference between 2D and 3D design is the level of depth and dimensionality. Additionally, 3D design allows for more complex and realistic designs to be created, such as detailed characters or intricate architectural models.

2D design are typically created on a computer screen or on paper. These designs are usually created using software such as Adobe Illustrator or Photoshop. They can be used for a wide variety of purposes, including creating logos, designing websites, or illustrating characters for games.

3D design, on the other hand  can be used for a variety of purposes, such as creating animated movies, designing video games, or even prototyping products in the manufacturing industry. 3D design requires more advanced software such as Maya, Blender, or ZBrush.

The benefits of creating 3D characters from 2D designs 

One of the biggest benefits of creating 3D characters from 2D designs is that it allows for a more immersive gaming experience. When players are able to see the character from all angles, they can appreciate the design more fully and feel more connected to the game world. Additionally, 3D characters can be animated in a way that 2D characters cannot, allowing for more lifelike movements and expressions.

Another benefit is that 3D models can be reused in different contexts, such as in cutscenes or marketing materials. This can save time and money in the long run.

Common challenges - how to make 2d pictures into perfect 3d models
