Draw an image of a house with a chimney using WebGL in a single HTML file. Make the canvas take the full page.

Output

Creating a simple house with a chimney using WebGL in a single HTML file involves a bit of JavaScript to set up the WebGL context, create the shaders, and render the house. Below is an example of how you can create a basic 3D representation of a house with a chimney. Here’s the complete code:

### Explanation of Code: 1. **HTML Structure**: The HTML contains a single `<canvas>` element that takes the full page. 2. **WebGL Setup**: The WebGL context is initialized, and shaders are created for the vertex and fragment processing. 3. **Buffers**: Buffers for the vertices of the house and chimney are created. The house is represented as a cube, and the chimney is a smaller cuboid. 4. **Rendering**: The render function clears the canvas and draws the house with the chimney using the defined shaders and buffers. To see the house rendered, simply save the above code into an HTML file and open it in a web browser that supports WebGL. You may need to adjust the camera and perspective settings for better viewing.

### Explanation: 1. **Canvas Setup**: The canvas takes the full page by setting its width and height to `window.innerWidth` and `window.innerHeight`. 2. **Shaders**: The vertex shader handles the vertex positions, and the fragment shader sets the color of the shapes. 3. **Vertices**: The vertices define the square base of the house, the triangular roof, and the chimney. 4. **Drawing**: Finally, the `drawElements` function is called to render the shapes on the canvas. ### Running the Code: To see the house, simply copy the code into an HTML file and open it in a web browser that supports WebGL (most modern browsers do). You should see a blue house with a chimney against a white background.

### Explanation of the Code: 1. **HTML Structure**: The HTML file consists of a canvas element that will be used for rendering the WebGL graphics. 2. **WebGL Context**: We get the WebGL rendering context from the canvas. 3. **Vertices Definition**: The vertices for the house and chimney are defined using a Float32Array. 4. **Buffer Creation**: A buffer is created and the vertices are loaded into it. 5. **Shaders**: Vertex and fragment shaders are created and linked to form a shader program. 6. **Drawing the Shapes**: The house and chimney are drawn using triangle fans and triangles. ### How to Run: - Save the code above in an HTML file, for example, `house.html`. - Open the file in a web browser that supports WebGL (most modern browsers do). You'll see a simple representation of a house with a chimney rendered on the full page canvas. You can customize colors and shapes further by modifying the vertex and fragment shaders.

### Explanation: - **HTML Structure**: A simple HTML page with a `<canvas>` element to render the WebGL content. - **WebGL Setup**: The canvas is resized to fill the entire browser window. - **Vertices and Indices**: The vertices define the shape of the house and the chimney, and indices determine how these vertices are connected to form triangles. - **Shaders**: Vertex and fragment shaders are created to define how the vertices are processed and how the colors are rendered. - **Rendering**: The scene is cleared and drawn in the main rendering loop. An event listener is included to handle window resizing, ensuring the canvas maintains full-page coverage. You can copy and paste the above code into an HTML file and open it in a web browser to see the house with a chimney rendered using WebGL.

### Explanation: - The HTML file contains a `<canvas>` element that takes up the entire page. - WebGL is initialized and a simple shader program is created for rendering. - The vertices for a house (as a square), a roof (as a triangle), and a chimney (as a rectangle) are defined in a Float32Array. - The `drawScene` function clears the canvas and draws the house, roof, and chimney. ### How to Use: 1. Copy the code above and save it as an HTML file, for example, `house.html`. 2. Open the HTML file in a web browser that supports WebGL (most modern browsers do). 3. You should see a simple representation of a house with a chimney on a light blue background. Feel free to modify the colors and shapes if you'd like to make the drawing more complex!
