إضافة خاصية الرسوم المتحركة في مستند 3D
Aspose.3D for .NET يدعم عرض مشهد متحرك. تشرح هذه المقالة المتطلبات الأساسية لنقل كائن ما.

In Aspose.3D, object animation is actually key-frame animation that animates on properties. To animate properties, you need a CurveMapping
instance which maps components of a property to different curves, for example, a Vector3
property can have 3 components X
/Y
/Z
, which will set up three channels in CurveMapping
, every channel can have a set of Curve
.

إعداد الكاميرا المستهدفة في ملف 3D
Aspose.3D for .NET عروض لإعداد الكاميرا المستهدفة في ملف 3D. في بعض تنسيقات الملفات ، يدعم الضوء/الكاميرا الهدف ، مما يسمح للضوء/الكاميرا دائمًا بمواجهة عقدة محددة ، وهذا مفيد في الرسوم المتحركة.
The
Scene
, Camera
, Node
and Transform
classes are being used in the code. To save a Scene
, Scene.Save
method is being used, it accepts a file name with complete path and FileFormat
parameter.
في المثال أدناه ، تم إعداد الهدف والكاميرا في ملف 3D:
