The following types are used in WebGL 接口。

WebGL 1

These types are used within a WebGLRenderingContext .

类型	Web IDL 类型	描述
`GLenum`	`unsigned long`	Used for enums. See also the list of constants .
`GLboolean`	`boolean`	A `布尔` .
`GLbitfield`	`unsigned long`	A bit field that stores multiple, logical bits. Used for example in `WebGLRenderingContext.clear()` .
`GLbyte`	`byte`	8-bit twos complement signed integer.
`GLshort`	`short`	16-bit twos complement signed integer.
`GLint`	`long`	32-bit twos complement signed integer.
`GLsizei`	`long`	Used for sizes (e.g. width and height of the drawing buffer).
`GLintptr`	`long long`	Special type for pointer arithmetic.
`GLsizeiptr`	`long long`	Special type for pointer arithmetic.
`GLubyte`	`octet`	8-bit twos complement unsigned integer.
`GLushort`	`unsigned short`	16-bit twos complement unsigned integer.
`GLuint`	`unsigned long`	32-bit twos complement unsigned integer.
`GLfloat`	`unrestricted float`	32-bit IEEE floating point number.
`GLclampf`	`unrestricted float`	Clamped 32-bit IEEE floating point number.

WebGL 2

These types are used within a WebGL2RenderingContext . All WebGL 1 types are used as well.

类型	Web IDL 类型	描述
`GLint64`	`long long`	Signed 64-bit integer number.

WebGL extensions

These types are used within WebGL extensions .

类型	Web IDL 类型	描述
`GLuint64EXT`	`long long`	Unsigned 64-bit integer number.
