Examples with Vector4d org.spongepowered.math.vector.Vector4d used on opensource projects

Example 1 with Vector4d

use of org.spongepowered.math.vector.Vector4d in project SpongeCommon by SpongePowered.

the class SpongeTransformation method transformDirection.

@Override
@NonNull
public Vector3d transformDirection(@NonNull final Vector3d original) {
    final Vector4d transformed = this.directionTransformation.transform(original.normalize().toVector4(1));
    final Vector3d result;
    if (this.performRounding) {
        result = new Vector3d(GenericMath.round(transformed.x(), 14), GenericMath.round(transformed.y(), 14), GenericMath.round(transformed.z(), 14));
    } else {
        result = transformed.toVector3();
    }
    return result.normalize();
}

Example 2 with Vector4d

use of org.spongepowered.math.vector.Vector4d in project SpongeCommon by SpongePowered.

the class SpongeTransformationBuilder method mirror.

@Override
@NonNull
public SpongeTransformationBuilder mirror(@NonNull final Axis axis) {
    if (Objects.requireNonNull(axis) == Axis.Y) {
        throw new IllegalArgumentException("The Y direction cannot be mirrored.");
    }
    final Vector4d scale = Vector4d.ONE.sub(axis.toVector3d().toVector4(0).mul(2));
    this.transformation = this.transformation.scale(scale);
    this.directionTransformation = this.directionTransformation.scale(scale);
    // Flip the x or z mirror if that's the axis.
    this.flipx = this.flipx ^ axis == Axis.X;
    this.flipz = this.flipz ^ axis == Axis.Z;
    return this;
}
