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
ArrayofDOMStringspecifying the the names of the varying variables to use. bufferMode- A
GLenumspecifying the mode to use when capturing the varying variables. Eithergl.INTERLEAVED_ATTRIBSorgl.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);
