Type alias IGLBufferUsage

A GLenum specifying the intended usage pattern of the data store for optimization purposes. Possible values:

gl.STATIC_DRAW: The contents are intended to be specified once by the application, and used many times as the source for WebGL drawing and image specification commands.
gl.DYNAMIC_DRAW: The contents are intended to be respecified repeatedly by the application, and used many times as the source for WebGL drawing and image specification commands.
gl.STREAM_DRAW: The contents are intended to be specified once by the application, and used at most a few times as the source for WebGL drawing and image specification commands.

When using a WebGL 2 context, the following values are available additionally:

gl.STATIC_READ The contents are intended to be specified once by reading data from WebGL, and queried many times by the application.
gl.DYNAMIC_READ The contents are intended to be respecified repeatedly by reading data from WebGL, and queried many times by the application.
gl.STREAM_READ The contents are intended to be specified once by reading data from WebGL, and queried at most a few times by the application
gl.STATIC_COPY The contents are intended to be specified once by reading data from WebGL, and used many times as the source for WebGL drawing and image specification commands.
gl.DYNAMIC_COPY The contents are intended to be respecified repeatedly by reading data from WebGL, and used many times as the source for WebGL drawing and image specification commands.
gl.STREAM_COPY The contents are intended to be specified once by reading data from WebGL, and used at most a few times as the source for WebGL drawing and image specification commands.
