A game engine's primary function in relation to game graphics is to render the game world and objects. This involves converting 3D models and textures into a 2D image that can be displayed on the player's screen.

Procedural generation is a technique for creating game worlds and objects algorithmically, rather than manually. It is not a rendering technique, as it does not directly generate images.

A shader is a program that defines the appearance of materials in a game world. It specifies how light interacts with the material, resulting in effects such as reflection, refraction, and shading.

A physics engine is not a type of game engine. It is a software library that simulates the physical properties of objects in a game world, such as gravity, collision detection, and motion.

Rendering is the process of converting 3D models and textures into a 2D image. This is done by a graphics processing unit (GPU), which calculates the color and position of each pixel in the image.

Custom scripting languages are not a common feature of modern game engines. Instead, most engines use standard programming languages such as C++ or C#.

A texture is a 2D image that is applied to a 3D model to define its appearance. Textures can include details such as color, shading, and patterns.

Procedural light is not a common type of lighting used in game graphics. Procedural techniques are typically used for generating textures and objects, not for lighting.

Modeling is the process of creating 3D models for a game. This can be done using a variety of software tools, such as 3D modeling software or game engines themselves.

Inverse kinematics is not a type of animation. It is a technique used to calculate the joint angles of a character model based on a desired pose.

A physics engine is used to simulate the physical properties of objects in a game world, such as gravity, collision detection, and motion. This allows for realistic interactions between objects and characters.

Scripts are not a type of game asset. They are pieces of code that define the behavior of objects and characters in a game.

Streaming is the process of loading and unloading game assets as needed. This allows for large game worlds and complex scenes to be rendered without having to load all of the assets into memory at once.

Isometric cameras are not a common type of camera used in game graphics. They are typically used in strategy games and RPGs to provide a top-down view of the game world.

A user interface (UI) in game graphics serves multiple purposes. It allows players to interact with the game, displays game information, and manages the game's settings.
