3D renderer only has a 2D implementation of `quad`

[unjust]

Trying to pass z coordinates to quad for 3d rendering doesn't work, there is no implementation for 12 args (which would contain z)

p5.js/src/webgl/3d_primitives.js

Lines 1027 to 1064 in 9851414

	p5.RendererGL.prototype.quad = function(x1, y1, x2, y2, x3, y3, x4, y4) {
	var gId =
	'quad|' +
	x1 +
	'|' +
	y1 +
	'|' +
	x2 +
	'|' +
	y2 +
	'|' +
	x3 +
	'|' +
	y3 +
	'|' +
	x4 +
	'|' +
	y4;
	if (!this.geometryInHash(gId)) {
	var _quad = function() {
	this.vertices.push(new p5.Vector(x1, y1, 0));
	this.vertices.push(new p5.Vector(x2, y2, 0));
	this.vertices.push(new p5.Vector(x3, y3, 0));
	this.vertices.push(new p5.Vector(x4, y4, 0));
	this.uvs.push(0, 0, 1, 0, 1, 1, 0, 1);
	this.strokeIndices = [[0, 1], [1, 2], [2, 3], [3, 0]];
	};
	var quadGeom = new p5.Geometry(2, 2, _quad);
	quadGeom
	.computeNormals()
	._makeTriangleEdges()
	._edgesToVertices();
	quadGeom.faces = [[0, 1, 2], [2, 3, 0]];
	this.createBuffers(gId, quadGeom);
	}
	this.drawBuffers(gId);
	return this;
	};

It would be my first issue, but I can attempt to fix.

@unjust great! You can find an example of how to parse the arguments in both forms at once in the bezier function just below:

p5.js/src/webgl/3d_primitives.js

Lines 1069 to 1108 in 9851414

	p5.RendererGL.prototype.bezier = function(
	x1,
	y1,
	z1, // x2
	x2, // y2
	y2, // x3
	z2, // y3
	x3, // x4
	y3, // y4
	z3,
	x4,
	y4,
	z4
	) {
	if (arguments.length === 8) {
	x4 = x3;
	y4 = y3;
	x3 = y2;
	y3 = x2;
	x2 = z1;
	y2 = x2;
	z1 = z2 = z3 = z4 = 0;
	}
	var bezierDetail = this._pInst._bezierDetail || 20; //value of Bezier detail
	this.beginShape();
	for (var i = 0; i <= bezierDetail; i++) {
	var c1 = Math.pow(1 - i / bezierDetail, 3);
	var c2 = 3 * (i / bezierDetail) * Math.pow(1 - i / bezierDetail, 2);
	var c3 = 3 * Math.pow(i / bezierDetail, 2) * (1 - i / bezierDetail);
	var c4 = Math.pow(i / bezierDetail, 3);
	this.vertex(
	x1 * c1 + x2 * c2 + x3 * c3 + x4 * c4,
	y1 * c1 + y2 * c2 + y3 * c3 + y4 * c4,
	z1 * c1 + z2 * c2 + z3 * c3 + z4 * c4
	);
	}
	this.endShape();
	return this;
	};

#3329

[unjust]

Apologies if my closing and opening another pull request messed things up.
This is the fix #3358

I don't see this issue in any milestone so lmk if I should just ignore the issue for now
