MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

WebGL2RenderingContext.getIndexedParameter()

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The WebGL2RenderingContext.getIndexedParameter() method of the WebGL 2 API returns indexed information about a given target.

Syntax

any gl.getIndexedParameter(target, index);

Parameters

target
A Glenum specifying the target for which to return information. Possible values:
  • gl.TRANSFORM_FEEDBACK_BUFFER_BINDING: Returns a WebGLBuffer.
  • gl.TRANSFORM_FEEDBACK_BUFFER_SIZE: Returns a GLsizeiptr.
  • gl.TRANSFORM_FEEDBACK_BUFFER_START: Returns a GLintptr.
  • gl.UNIFORM_BUFFER_BINDING: Returns a WebGLBuffer.
  • gl.UNIFORM_BUFFER_SIZE: Returns a GLsizeiptr.
  • gl.UNIFORM_BUFFER_START: Returns a GLintptr.
index
A GLuint specifying the index of the target that is queried.

Return value

Depends on the requested information (as specified with target).

Examples

var binding = gl.getIndexedParameter(gl.TRANSFORM_FEEDBACK_BUFFER_BINDING, 0);
