WebGL2RenderingContext.transformFeedbackVaryings()

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

Syntax

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

Parameters

program
A WebGLProgram.
varyings
An Array of DOMString specifying the 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);
