如何更改 3D 场景的观察点

问题： 如何更改 3D 场景的观察点。

提示： 要做到这一点，您可以使用 ObserverPoint 类来更改观察点，要更新观察点，您需要创建一个 CadRasterizationOptions 对象并将其添加到转换选项中。

示例：

ObjImage objImage = (ObjImage)Image.load(inFile);

CadRasterizationOptions objRasterizationOptions = new CadRasterizationOptions();

PngOptions pngOptions = new PngOptions();
pngOptions.VectorRasterizationOptions = objRasterizationOptions;

objRasterizationOptions.PageHeight = 1600;
objRasterizationOptions.PageWidth = 1600;
objRasterizationOptions.DrawType = CadDrawTypeMode.UseObjectColor;

objRasterizationOptions.ObserverPoint = new ObserverPoint(45, 45, 45);
objImage.save(inFile + "1.png", pngOptions);

objRasterizationOptions.ObserverPoint = new ObserverPoint(45, -45, -45);
objImage.save(inFile + "2.png", pngOptions);

objRasterizationOptions.ObserverPoint = new ObserverPoint(-45, -45, -45);
objImage.save(inFile + "3.png", pngOptions);
