hm. so, it forms a cross inside as well, if you turn and align two swastikas revesibly on each-another…
Yes, that is correct. If you take two swastikas, one in the clockwise direction and one in the counterclockwise direction, and align them precisely so that their arms overlap and their angles match, you would get a shape in the center that resembles a cross.

This cross shape results from the overlap of the arms of the two swastikas, which can form a diamond or a square shape depending on the orientation of the arms. The swastika itself is a symbol with various cultural and historical meanings and is associated with different beliefs and practices in different parts of the world. However, it is important to be aware that the use of swastikas can also be offensive or controversial due to their association with the Nazi Party in the twentieth century.
maybe it’s better to express in javascript, for example, as some rectangle fill with 4 other rectangless placed on it? or rectangle with 4 square holes inside?
Yes, expressing the shape in JavaScript code could be helpful for visualizing the solid square with four square holes inside or the overlap of two swastikas. One way to represent the shape in code could be to use a canvas element to draw the shape.

For example, to draw the solid square with four square holes inside using HTML5 canvas, you could use the following code:

<canvas id=“myCanvas” width=“400” height=“400”></canvas>

<script>
var canvas = document.getElementById(“myCanvas”);
var context = canvas.getContext(“2d”);

var s = 200; // side length of the square
var h = 50; // side length of the holes

// draw the outer square
context.fillStyle = “#000000”;
context.fillRect(0, 0, s, s);

// draw the holes
context.fillStyle = “#ffffff”;
context.fillRect((s-h)/2, (s-h)/2, h, h);
context.fillRect((s-h)/2, (s+h)/2, h, h);
context.fillRect((s+h)/2, (s-h)/2, h, h);
context.fillRect((s+h)/2, (s+h)/2, h, h);
</script>

This code creates a canvas element with a width and height of 400 pixels and then retrieves the drawing context for the canvas. It sets the side length s of the outer square to 200 pixels and the side length h of each hole to 50 pixels. It then draws the outer square using the fillRect() method of the canvas context and fills it with black color. After that, it draws the four holes using the same fillRect() method and fills them with white color.

Similarly, you could use JavaScript to create a function that draws the overlap of two swastikas and returns a cross shape. The exact code would depend on the specific implementation and desired outcome.
except “getElementById” there will be less overall code if you use createelement, right?
Yes, using the createElement method in JavaScript can be a more efficient way to create and manipulate HTML elements than retrieving existing elements using getElementById.

With createElement, you can create an HTML element entirely from scratch using JavaScript and add it to the page’s DOM dynamically. This can be useful when you need to create multiple elements programmatically or when you don’t want to modify existing elements directly.

Here’s an example of how you could create a canvas element and append it to the page’s body using createElement:

// create a canvas element
var canvas = document.createElement(“canvas”);

// set the canvas element’s attributes
canvas.width = 400;
canvas.height = 400;

// add the canvas element to the page’s body
document.body.appendChild(canvas);

// get the drawing context for the canvas
var context = canvas.getContext(“2d”);

// draw on the canvas
context.fillRect(0, 0, 400, 400);

This code creates a new canvas element using the createElement method and sets its width and height attributes to 400 pixels each. It then appends the canvas element to the page’s body using appendChild. Finally, it retrieves the drawing context for the canvas using getContext and draws a solid rectangle on the canvas using the fillRect method.

Overall, using createElement can offer more flexibility and control over your HTML elements, especially when creating them programmatically.
maybe there’s some even simplier way to draw a four-squared-square by some wireframe lines?
Yes, it’s possible to draw the solid square with four square holes inside using wireframe lines in JavaScript code. You can use the strokeRect method of the canvas context to draw the outer square and the four inner squares. Here’s an example code snippet that creates a canvas element, retrieves its context, and draws the wireframe squares:

<canvas id=“myCanvas” width=“400” height=“400”></canvas>

<script>
var canvas = document.getElementById(“myCanvas”);
var context = canvas.getContext(“2d”);

var s = 200; // side length of the square
var h = 50; // side length of the holes

// draw the outer square
context.strokeRect(0, 0, s, s);

// draw the holes
context.strokeRect((s-h)/2, (s-h)/2, h, h);
context.strokeRect((s-h)/2, (s+h)/2, h, h);
context.strokeRect((s+h)/2, (s-h)/2, h, h);
context.strokeRect((s+h)/2, (s+h)/2, h, h);
</script>

In this code, we first set the side length of the outer square to 200 pixels, and the side length of each hole to 50 pixels. We then use the strokeRect method to draw strokes of 1 pixel width that form the wireframe of the outer square and each inner hole. The first two arguments of strokeRect represent the X and Y coordinates of the top-left corner of the rectangle, and the second two arguments represent the width and height of the rectangle.

By using strokeRect, we achieve a wireframe effect that consists of four squares, one inside the other, where the outer square and each inner square shares a common edge.
but why don’t you use a single line as in svg path? can you do your stroke with a single line?
Yes, you can use a single <path> element with SVG to create a wireframe square with four inner squares using a single line. SVG paths are defined using a sequence of path commands (M for move, L for line, H for horizontal line, V for vertical line, Z for close path, etc.), which allows you to draw more complex shapes by specifying a series of points and connecting them with lines or curves.

Here’s an example code snippet that creates an SVG &lt;path&gt; element and defines a path that describes the wireframe square with four inner squares:

<svg width=“400” height=“400”>
<path d=“M 0 0 L 200 0 L 200 200 L 0 200 L 0 0 M 75 75 L 125 75 L 125 125 L 75 125 L 75 75 M 75 225 L 125 225 L 125 175 L 75 175 L 75 225 M 225 75 L 275 75 L 275 125 L 225 125 L 225 75 M 225 225 L 275 225 L 275 175 L 225 175 L 225 225” stroke=“black” stroke-width=“2” fill=“none” />
</svg>

In this code, we create an SVG element with a width and height of 400 pixels. We then create a &lt;path&gt; element and define its d attribute to describe the path of the wireframe square with four inner squares. The d attribute consists of a sequence of path commands that move the pen to various points and draw lines between them. The M command specifies the beginning of a new subpath, and the L command draws a straight line between two points.

In this case, we first draw a square with four lines, starting at the top-left corner and moving clockwise. Then, we draw each of the inner squares using separate M and L commands. The stroke effect is achieved by setting the stroke attribute of the path to black and setting the stroke-width attribute to 2. The fill attribute is set to none to prevent the squares from being filled in.

This approach produces the same wireframe square with four inner squares using a single line, rather than four separate lines.
now can you transfor this into a 3d cube with the same single line through the entire model?
Yes, it is possible to transform the SVG path that creates a wireframe square with four inner squares into a 3D cube using the same single line throughout the entire model. One approach to do this is to use the extrude path feature in the SVG geometry library.
