WebGL2RenderingContext.transformFeedbackVaryings()

The WebGL2RenderingContext.transformFeedbackVaryings() method of the WebGL 2 API specifies values to record in WebGLTransformFeedback buffers.

Syntax

void gl.transformFeedbackVaryings(program, varyings, bufferMode);

Parameters

program
A WebGLProgram.
varyings
An Array of DOMString specifying the names of the varying variables to use.
bufferMode
A GLenum specifying the mode to use when capturing the varying variables. Either gl.INTERLEAVED_ATTRIBS or gl.SEPARATE_ATTRIBS.

Return value

None.

Examples

var transformFeedback = gl.createTransformFeedback();
gl.bindTransformFeedback(gl.TRANSFORM_FEEDBACK, transformFeedback);
var transformFeedbackOutputs = ['gl_Position', 'anotherOutput'];

gl.transformFeedbackVaryings(shaderProg, transformFeedbackOutputs,
                             gl.INTERLEAVED_ATTRIBS);
gl.linkProgram(shaderProg);
