Extrude planar

In 3D computer graphics, extrude planar means to create a 3D object from a 2D planar object by extending it along a specified direction. The resulting 3D object is called an extrusion.

The process of extruding a planar object is typically done by specifying the following:

• The 2D planar object to be extruded.
• The direction along which the extrusion will be performed.
• The distance or height to which the extrusion will extend.
• The profile of the extrusion.

The profile of the extrusion can be a simple shape, such as a rectangle or a circle, or it can be a more complex shape, such as a text string or a logo.

The extrusion process can be used to create a wide variety of 3D objects, such as boxes, cylinders, cones, and even more complex shapes.

Here are some examples of extruded planar objects:

• A box is created by extruding a rectangle along a vertical direction.
• A cylinder is created by extruding a circle along a vertical direction.
• A cone is created by extruding a circle along a vertical direction and then tapering the sides.
• A text string is created by extruding a 2D text string along a vertical direction.

The extrusion process is a powerful tool that can be used to create a wide variety of 3D objects. It is a common operation in many 3D computer graphics software packages.
