Master Basic Rendering Techniques

Step 1: Setting up the Scene

In this first step, we’ll create a 3D scene and set up a camera and lighting.

protected static Camera setupScene(Scene scene) {
    // Code for setting up camera and lighting
    // ...
    return camera;
}

Step 2: Creating a Plane

Now, let’s add a plane to our scene with a specified color.

Node plane = scene.getRootNode().createChildNode("plane", (new Plane(20, 20)).toMesh());
applyMaterial(plane, new Color(0xff8c00));
plane.getTransform().setTranslation(0, 0, 0);
((Mesh)plane.getEntity()).setReceiveShadows(true);

Step 3: Adding a Torus

Next, we’ll introduce a torus to our scene with a transparent material.

Mesh torusMesh = (new Torus("", 1, 0.4, 50, 50, Math.PI*2)).toMesh();
Node torus = scene.getRootNode().createChildNode("torus", torusMesh);
applyMaterial(torus, new Color(0x330c93)).setTransparency(0.3);
torus.getTransform().setTranslation(2, 1, 1);

Step 4: Incorporating Cylinders

Now, let’s add cylinders to the scene with different rotations and materials.

// Code for adding cylinders with specific rotations and materials
// ...

Step 5: Configuring the Camera

In the final step, we’ll configure the camera to get the desired view of the scene.

Camera camera = new Camera();
scene.getRootNode().createChildNode(camera);
camera.setNearPlane(0.1);
camera.getParentNode().getTransform().setTranslation(10, 5, 10);
camera.setLookAt(Vector3.ORIGIN);
return camera;

Congratulations! You’ve successfully mastered basic rendering techniques for 3D scenes in Java using Aspose.3D.
