Hello thanks for your interest. My code:
function Maquette(){
var positions = new Float64Array(4 * 3);
var A={x:0,y:3.5,z:0};
var B={x:1.500,y:-1.000,z:0};
var D={x:-1.500,y:-1.000,z:0};
var E={x:0,y:-1.000,z:1.500};
positions[0] = A.x;
positions[1] = A.y;
positions[2] = A.z;
positions[3] = B.x;
positions[4] = B.y;
positions[5] = B.z;
positions[6] = D.x;
positions[7] = D.y;
positions[8] = D.z;
positions[9] = E.x;
positions[10] = E.y;
positions[11] = E.z;
var indices = new Uint16Array(4 * 3);
// back triangle AEB
indices[0] = 0;
indices[1] = 3;
indices[2] = 1;
// left triangle EAD
indices[3] = 3;
indices[4] = 0;

indices[7] = 2;
indices[8] = 1;
// bottom triangle BAD
indices[9] = 1;
indices[10] = 0;
indices[11] = 3;
