Vector4
Example
Vector4 je vektor duple preciznosti sa 4 komponente. To je tip skladištenja za kontrolne tačke mreže (gde w = 1.0 za pozicije) i za normalne podatke u VertexElementNormal slojevima (gde w nije korišćen).
Example: com.aspose.threed
import com.aspose.threed.*;
Vector4 point = new Vector4(1.0, 2.0, 3.0, 1.0);Example
| Signature | Description |
|---|---|
Vector4() | Initializes a vector with the specified x, y, z, and w component values |
Vector4(x: double, y: double, z: double, w: double) | Calls Vector4(x, y, z, w) on this Vector4 instance. |
Javna polja
Vector4 koristi javna polja za pristup komponentama (ne metode getter/setter):
Example
Example
import com.aspose.threed.*;
Mesh mesh = new Mesh();
// Add control points (w=1.0 for positions)
mesh.getControlPoints().add(new Vector4(0.0, 0.0, 0.0, 1.0));
mesh.getControlPoints().add(new Vector4(1.0, 0.0, 0.0, 1.0));
mesh.getControlPoints().add(new Vector4(0.5, 1.0, 0.0, 1.0));
mesh.createPolygon(0, 1, 2);
// Convert to Vector3
Vector4 v4 = new Vector4(1.0, 2.0, 3.0, 1.0);
Vector3 v3 = v4.toVector3(); // Vector3(1.0, 2.0, 3.0)
// Construct from Vector3
Vector3 pos = new Vector3(5.0, 0.0, 0.0);
Vector4 homogeneous = new Vector4(pos); // w = 1.0
