Emma is learning GLSL for her graphics programming class. She comes across a concept that describes a specific type of data structure used in her shaders. What is a vector in GLSL?

• A function for rendering

• A single float value

• A 2, 3, or 4 component container for basic types

• A type of shader

In a graphics programming class, Ethan is learning about GLSL and comes across a feature called swizzling. He wonders what swizzling allows him to do in his shader programs.

• Creating loops in shaders

• Defining new data types

• Accessing vector components in a flexible way

• Changing the shader type

In a graphics programming class, Evelyn is learning about GLSL and comes across the 'out' keyword. She wonders what its purpose is in shader programming.

• To manage shader programs

• To create uniforms

• To define output variables

• To declare input variables

In a graphics programming class, Rohan is learning about GLSL. His instructor explains that a uniform is a special type of variable used in shaders. What is a uniform in GLSL?

• A type of shader

• An input variable

• A global variable unique per shader program

• A local variable
