The WebGL2RenderingContext.getIndexedParameter() method of the WebGL 2 API returns indexed information about a given target.
getIndexedParameter(target, index)
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.When using the OES_draw_buffers_indexed WebGL 2 extension, the following values are available additionally:
gl.BLEND_EQUATION_RGB: Returns the RGB blend equation for the draw buffer at index.gl.BLEND_EQUATION_ALPHA: Returns the alpha blend equation for the draw buffer at index.gl.BLEND_SRC_RGB: Returns the source RGB blend function for the draw buffer at index.gl.BLEND_SRC_ALPHA: Returns the source alpha blend function for the draw buffer at index.gl.BLEND_DST_RGB: Returns the destination RGB blend function for the draw buffer at index.gl.BLEND_DST_ALPHA: Returns the destination alpha blend function for the draw buffer at index.gl.COLOR_WRITEMASK: Returns an array containing color components are enabled for the draw buffer at index.index
A GLuint specifying the index of the target that is queried.
Depends on the requested information (as specified with target).
const binding = gl.getIndexedParameter(gl.TRANSFORM_FEEDBACK_BUFFER_BINDING, 0);
