Check the Browser compatibility table carefully before using this in production.
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
ofDOMString
specifying the the names of the varying variables to use. bufferMode
- A
GLenum
specifying the mode to use when capturing the varying variables. Eithergl.INTERLEAVED_ATTRIBS
orgl.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);
