using (Viewer viewer = new Viewer("sample.obj"))
{
HtmlViewOptions options = HtmlViewOptions.ForEmbeddedResources("output.html");
//options.CadOptions = CadOptions.ForRenderingByScaleFactor(0.7f); // Render image and reduce it by 30%
//options.CadOptions = CadOptions.ForRenderingByWidthAndHeight(400,400); // Render image and set output size to 400x400
//options.CadOptions = CadOptions.ForRenderingByWidth(500); // Render image, fix width by 500 px and recalculate height
//options.CadOptions = CadOptions.ForRenderingByHeight(500); // Render image, fix height by 500 px and recalculate width
viewer.View(options);
}
The following screenshot shows the output HTML file opened in a browser.
Convert OBJ to JPG
