Matrix3D problem

Anonymous — Tue, 04 Mar 2008 13:09:30 GMT

Hello, Guys.

In Arx the class AcGeMatrix3d has methods like 'setToTranslation', 'setToRotation'. In .NET this are now readonly properties. Does anyone know how to set this in .NET?

I would really appreciate the help, friends.

The properties are read-only because the managed Matrx3d is a struct/value type (e.g., its fields cannot be modified).

Matrix3d m = Matrix3d.Identity;

// Set translation:

m *= Matrix3d.Displacement( new Vector3d( x, y, z )); // x,y,z translation

// Set rotation (rotate by PI/2 around WCS Z axis)

m *= Matrix3d.Rotation( Math.PI/2.0, Vector3d.ZAxis, Point3d.Origin );
