Can we find neckpoints having face coordinates i.e. faceCoo.x, y, z and detectface.rx, ry, rz?

Hi,

You have to:

• match a 3D model with the user's face like in the Matrix Facefilter tutorial
• the 3D model is moved with the detectstate
• you take the coordinates of the point matching the neck for example and you multiply it with the wordmatrix.

I suggest you, before working with this library, to learn basics of 3D programming. You can start here: http://webglacademy.com/ or there: http://learningwebgl.com/blog/?page_id=1217

Thanks a lot

The tutorial was awesome.
how to get coordinates of points matching the neck? and where is the wordmatrix?

Hi,

I am sorry but this is not a beginner 3D forum. Your question is not about faceFilter.
I have a lot of work, I put detailed explanation about all detectFace properties, and there are many commented demos to have examples. I don't have time to explain basic 3D concepts like projection or the worldmatrix. You have to learn them by yourself.

okay, sorry & thank you

The script.js here http://webglacademy.com/courses.php?courses=0_1_20_2_3_4_23_5_6_7_10#20
is lagging while scrolling.

Hi,

This is because you are running a very heavy shader (I suppose you are in the last steps and you have clicked on RUN button).
So your resources are so busy that it makes the DOM slow.
In order to force the computer to not fully use the resources for the shader, you can replace window.requestAnimationFrame(animate); on script.js by:

 window.requestAnimationFrame(tickAnimate);

and declare tickAnimate just after animate by:

var tickAnimate=function(timestamp){
   setTimeout(animate.bind(null, timestamp), 5); //5 is short time in ms where the browser is idle so it can refresh easily
}
