2‑D Transformations
The Windows graphics stack provides a set of 2‑D transformation APIs that can be used with Matrix3x2F, CanvasDrawingSession, and GDI+.
- Translate –
Matrix3x2F.Translation - Scale –
Matrix3x2F.Scale - Rotate –
Matrix3x2F.Rotation - Skew –
Matrix3x2F.Skew
Matrix3x2F m = Matrix3x2F.Identity;
m = Matrix3x2F.Rotation(angle) * Matrix3x2F.Scale(sx, sy) * Matrix3x2F.Translation(tx, ty);3‑D Transformations
For 3‑D graphics, Windows provides Matrix4x4 and the Direct2D/Direct3D integration.
- Perspective –
Matrix4x4.CreatePerspectiveFieldOfView - Look‑At –
Matrix4x4.CreateLookAt - Rotation –
Matrix4x4.CreateFromYawPitchRoll
Matrix4x4 view = Matrix4x4.CreateLookAt(cameraPos, target, up);
Matrix4x4 proj = Matrix4x4.CreatePerspectiveFieldOfView(fov, aspect, nearZ, farZ);Live Sample: Interactive Transformation Demo
