### Create WordArt with 3D Effects

Source: https://context7.com/aspose-slides/aspose.slides-for-java/llms.txt

Applies various effects like shadow, glow, and 3D bevels to text within a shape. This example demonstrates setting font properties, text transformations, and 3D formatting. Ensure the `Presentation` object is disposed after use.

```java
import com.aspose.slides.*;
import java.awt.Color;

Presentation pres = new Presentation();
try {
    IAutoShape shape = pres.getSlides().get_Item(0).getShapes()
        .addAutoShape(ShapeType.Rectangle, 100, 100, 400, 150);
    ITextFrame tf = shape.getTextFrame();

    Portion portion = (Portion) tf.getParagraphs().get_Item(0).getPortions().get_Item(0);
    portion.setText("WordArt Demo");
    portion.getPortionFormat().setLatinFont(new FontData("Arial Black"));
    portion.getPortionFormat().setFontHeight(36);

    // Outer shadow
    portion.getPortionFormat().getEffectFormat().enableOuterShadowEffect();
    portion.getPortionFormat().getEffectFormat().getOuterShadowEffect()
        .getShadowColor().setColor(Color.BLACK);
    portion.getPortionFormat().getEffectFormat().getOuterShadowEffect().setBlurRadius(4.73);
    portion.getPortionFormat().getEffectFormat().getOuterShadowEffect().setDirection(230);

    // Glow
    portion.getPortionFormat().getEffectFormat().enableGlowEffect();
    portion.getPortionFormat().getEffectFormat().getGlowEffect().getColor().setR((byte) 255);
    portion.getPortionFormat().getEffectFormat().getGlowEffect().setRadius(7);

    // Arc text transform
    tf.getTextFrameFormat().setTransform(TextShapeType.ArchUpPour);

    // 3D bevel on shape
    shape.getThreeDFormat().getBevelTop().setBevelType(BevelPresetType.Circle);
    shape.getThreeDFormat().getBevelTop().setHeight(12.5);
    shape.getThreeDFormat().setDepth(3);
    shape.getThreeDFormat().setMaterial(MaterialPresetType.Plastic);

        .addEffect(box, EffectType.PathFootball, 
                   EffectSubtype.None, EffectTriggerType.AfterPrevious);

    // Custom user-path motion on button click
    IShape btn = sld.getShapes().addAutoShape(ShapeType.Bevel, 10, 10, 20, 20);
    ISequence seq = sld.getTimeline().getInteractiveSequences().add(btn);
    IEffect fx = seq.addEffect(box, EffectType.PathUser, 
                               EffectSubtype.None, EffectTriggerType.OnClick);

    IMotionEffect motion = (IMotionEffect) fx.getBehaviors().get_Item(0);
    Point2D.Float[] pts = (Point2D.Float[]) Array.newInstance(Point2D.Float.class, 1);
    pts[0] = new Point2D.Float(0.076f, 0.59f);
    motion.getPath().add(MotionCommandPathType.LineTo, pts, MotionPathPointsType.Auto, true);
    pts[0] = new Point2D.Float(-0.076f, -0.59f);
    motion.getPath().add(MotionCommandPathType.LineTo, pts, MotionPathPointsType.Auto, false);
    motion.getPath().add(MotionCommandPathType.End, null, MotionPathPointsType.Auto, false);
