Rendering OBJ to HTML

Overview: Convert 3D models into interactive, web-friendly HTML pages with embedded resources.

Step-by-Step Guide:

Set Up the Output Directory

Path outputDirectory = Paths.get("YOUR_OUTPUT_DIRECTORY");
Path pageFilePathFormat = outputDirectory.resolve("obj_result.html");

Create Viewer Instance

try (Viewer viewer = new Viewer("YOUR_DOCUMENT_DIRECTORY/SAMPLE_OBJ")) {
    // Code for rendering will go here
}

Configure HTML View Options

HtmlViewOptions options = HtmlViewOptions.forEmbeddedResources(pageFilePathFormat);

Render the OBJ Document
```
viewer.view(options);
```

Explanation: The HtmlViewOptions class ensures resources are embedded directly within HTML, providing a seamless viewing experience.

Rendering OBJ to JPG

Overview: Convert 3D models into high-quality JPEG images for easy sharing and display.

Step-by-Step Guide:

Set Up the Output Directory

Path outputDirectory = Paths.get("YOUR_OUTPUT_DIRECTORY");
Path pageFilePathFormat = outputDirectory.resolve("obj_result.jpg");

Create Viewer Instance

try (Viewer viewer = new Viewer("YOUR_DOCUMENT_DIRECTORY/SAMPLE_OBJ")) {
    // Code for rendering will go here
}

Configure JPG View Options

JpgViewOptions options = new JpgViewOptions(pageFilePathFormat);

Render the OBJ Document
```
viewer.view(options);
```

Explanation: The JpgViewOptions class handles conversion settings, including output path and image quality.

Rendering OBJ to PNG

Overview: Transform 3D models into PNG format, perfect for maintaining transparency in images.

Step-by-Step Guide:

Set Up the Output Directory

Path outputDirectory = Paths.get("YOUR_OUTPUT_DIRECTORY");
Path pageFilePathFormat = outputDirectory.resolve("obj_result.png");

Create Viewer Instance

try (Viewer viewer = new Viewer("YOUR_DOCUMENT_DIRECTORY/SAMPLE_OBJ")) {
    // Code for rendering will go here
}

Configure PNG View Options

PngViewOptions options = new PngViewOptions(pageFilePathFormat);

Render the OBJ Document
```
viewer.view(options);
```

Explanation: The PngViewOptions class configures PNG file generation, ideal for graphics requiring transparency.

Rendering OBJ to PDF

Overview: Convert 3D models into professional PDF documents suitable for distribution and printing.

Step-by-Step Guide:

Set Up the Output Directory

Path outputDirectory = Paths.get("YOUR_OUTPUT_DIRECTORY");
Path pageFilePathFormat = outputDirectory.resolve("obj_result.pdf");

Create Viewer Instance

try (Viewer viewer = new Viewer("YOUR_DOCUMENT_DIRECTORY/SAMPLE_OBJ")) {
    // Code for rendering will go here
}

Configure PDF View Options

PdfViewOptions options = new PdfViewOptions(pageFilePathFormat);

Render the OBJ Document
```
viewer.view(options);
```

Explanation: The PdfViewOptions class ensures accurate rendering into a portable and widely accepted PDF format.
