Drawing three-dimensional (3D) shapes involves creating the illusion of depth on a flat surface.

In this class, we will look at the video on how light hits an apple and creates a shadow. Then, we will learn how to draw and color objects so that each object looks three-dimensional, even though it’s on a two-dimensional piece of paper. 

Here's a step-by-step guide to help you draw basic 3D shapes:

1. Understand Basic Shapes:

• Start with basic 2D shapes, like squares, circles, rectangles, or triangles. Familiarize yourself with drawing these shapes accurately.

2. Add Depth with Perspective:

• Understand the concept of perspective. In one-point perspective, all lines converge to a single point on the horizon. In two-point perspective, two vanishing points are used.

3. One-Point Perspective Cube:

• Let's start with a simple cube using one-point perspective:

• Draw a square as the front face of the cube.

• Choose a vanishing point on the horizon line.

• Draw lines from each corner of the square to the vanishing point.

4. Two-Point Perspective Cube:

• For a cube in two-point perspective:

• Draw a vertical line for one corner of the cube.

• Add two vanishing points on the horizon line.

• Draw lines from the top and bottom of the vertical line to each vanishing point.

5. Cylinder:

• Draw an ellipse for the top or bottom of the cylinder.
• Connect the corresponding points on the ellipse with straight lines to create the sides.
• Add shading to enhance the 3D effect.

6. Sphere:

• Draw a perfect circle as the base of the sphere.
• Add shading to give it a rounded appearance.
• Consider where the light source is and shade accordingly.

7. Pyramid:

• Start with a square as the base of the pyramid.
• Draw lines from each corner of the square to a single point at the top.

8. Practice with Objects:

• Choose everyday objects with simple shapes (e.g., a box, a can, or a book).
• Observe how light interacts with the surfaces and replicate it in your drawing.

9. Use Value and Shading:

• Create depth by adding shading. Understand how light and shadow play on the surfaces of your 3D shapes.

10. Experiment and Refine:

• Don't be afraid to experiment with different shapes and perspectives. Practice regularly to refine your skills.

Tips:

• Pay attention to the size and spacing of objects as they recede into the distance.
• Consistency in your chosen perspective is key for a realistic look.
• Use guidelines lightly and erase them as needed.

Remember, practice is essential for mastering the art of drawing 3D shapes. As you become more comfortable, you can tackle more complex forms and scenes.
