The following types are used in WebGL interfaces.
The following types are used in WebGL interfaces.
These types are used within a WebGLRenderingContext.
| Type | Web IDL type | Description |
|---|---|---|
GLenum | unsigned long | Used for enums. See also the list of constants. |
GLboolean | boolean | A boolean value. |
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. |
These types are used within a WebGL2RenderingContext. All WebGL 1 types are used as well.
