立体方块怎么画简体图
This HTML document utilizes the HTML canvas element and JavaScript to draw a cube diagram. The cube is drawn using the `drawCube` function, which takes the cube's center coordinates, size, and color as parameters. The function first saves the current drawing state, then translates to the center of the cube, fills the front face, and draws the edges. Finally, it draws the top and side faces before restoring the previous drawing state. You can modify the cube's properties and experiment with rotations to create different visualizations.
const canvas = document.getElementById('cubeCanvas');
ctx.lineWidth = 2;
ctx.save();
// Set the fill color
// Draw the edges of the cube
// Rotate the cube (optional)
y: 100, // ycoordinate of the cube's center
ctx.beginPath();
ctx.translate(x, y);
ctx.beginPath();
ctx.lineTo(size / 2, size / 2);
ctx.moveTo(size / 2, size / 2);
ctx.stroke();
ctx.fill();
ctx.moveTo(size / 2, size / 2);
