Lesson Content/Board Summary

3D Modelling With Paint 3D: Purpose Of Paint 3D

Purpose of Paint 3D

Paint 3D is a creative application that allows users to create and manipulate 3D objects and scenes easily. Its main purposes include:

1. Creating 3D Models: It enables users to design and build three-dimensional shapes and objects from scratch or by modifying existing ones.
2. Editing 2D Images: While primarily for 3D, it also offers tools for basic 2D image editing and drawing.
3. Adding 3D Effects to 2D Images: Users can combine 2D images with 3D objects to create mixed-reality scenes.
4. Easy Sharing: It facilitates sharing created 3D models and scenes with others, often integrated with online communities.
5. Educational Tool: It serves as an excellent introductory tool for learning about 3D design concepts due to its intuitive interface.

Description of 3D Modelling and its Uses

3D modelling is the process of developing a mathematical representation of any three-dimensional surface of an object (either inanimate or living) via specialized software. The product is called a 3D model.

Uses of 3D modelling include:

1. Gaming: Creating characters, environments, and objects for video games.
2. Animation and Film: Designing characters, props, and special effects for movies and animated series.
3. Architecture: Visualizing building designs and interior layouts.
4. Engineering: Prototyping and designing products, machinery, and components.
5. Medical Imaging: Creating detailed models of organs and body parts for study and surgical planning.
6. Product Design: Developing new products and packaging.

Elements of Paint 3D User Interface

The Paint 3D user interface includes several key elements:

1. Menu Bar: Contains options like New, Open, Save, Share, and Print.
2. Toolbar: Located at the top, it provides access to various tools such as Brushes, 2D shapes, 3D shapes, Stickers, Text, Effects, Canvas, and Magic Select.
3. Canvas: The main working area where 2D and 3D objects are created and manipulated.
4. Sidebar/Panel: Appears on the right side, displaying options and settings specific to the selected tool (e.g., brush type, colour, thickness).
5. View Cube: Allows users to change the viewing angle of the 3D canvas.
6. Undo/Redo Buttons: For reversing or re-applying actions.

Tools for 3D Modelling in Paint 3D

Paint 3D offers various tools to create and manipulate 3D objects:

1. 3D Shapes: This tool allows users to create basic 3D objects like cubes, spheres, cones, cylinders, and capsules. It also includes a 3D doodle tool for freehand 3D drawing.
2. 3D Doodle:
   1. Sharp Edge 3D Doodle: Used to draw 3D objects with straight, sharp edges.
   2. Soft Edge 3D Doodle: Used to draw 3D objects with smooth, rounded edges.
3. Brushes: Although primarily for 2D, brushes can be used to add textures and colours to 3D objects.
4. Stickers: Allows applying 2D images as textures onto 3D models.
5. Text: Enables adding 2D or 3D text to the scene.
6. Magic Select: An intelligent tool that helps to quickly select and cut out parts of a 2D image to turn them into 3D objects.
7. Rotation and Movement Controls: Tools to rotate, resize, and move 3D objects in the X, Y, and Z axes.

Teacher Guide for Using This Lesson Plan

Before the lesson, ensure all computers or digital devices have Paint 3D installed and are in good working condition. Test the projector or interactive whiteboard if you plan to use one for demonstrations. Begin by engaging students with questions about 3D objects to activate prior knowledge. Clearly demonstrate each tool and interface element before allowing students to practice. During the practical activity, circulate around the classroom to provide individual support and address any technical issues. Emphasise safety when handling digital devices. Students should copy the Board Summary notes after the practical application and evaluation to consolidate their learning. Encourage creativity and exploration while ensuring they meet the basic objectives of identifying tools and creating simple 3D forms. Check for understanding frequently through questions and observation of their practical work.
