viewdef

Viewdef is a term used in the context of computer graphics and rendering, particularly within certain software or pipelines. It generally refers to a definition or specification of a "view" within a 3D scene. This view encompasses all the necessary parameters to determine how a particular part of the scene will be rendered or displayed to the user.

Key components of a viewdef often include camera parameters such as position, orientation, field of view, and projection type (e.g., perspective or orthographic). It also defines the clipping planes that determine which parts of the scene are visible and which are cut off. Additionally, a viewdef might specify render targets, such as the resolution of the output image, and any associated render states or effects that should be applied during rendering.

In essence, a viewdef acts as a blueprint for rendering a specific perspective of a virtual environment. Different viewdefs can be created to represent various viewpoints, such as the primary camera, a minimap, a rearview mirror, or a character's first-person perspective. Managing and switching between these viewdefs allows for dynamic camera control and diverse visual representations within an application. The exact implementation and terminology can vary between different graphics engines and frameworks.
