3D Cube

Level 1: Single Cube

Explore the structure of a 3D cube by rotating it interactively. This exercise helps you understand how cubes look from different angles, which is essential for drawing boxes, buildings, and other rectangular forms in perspective.

How to Use

1. Click and drag on the cube above to rotate it
2. Observe how the faces change as you rotate
3. Notice which faces are visible from different angles
4. Study how the transparent faces overlap

Key Observations

• A cube has 6 faces - front, back, left, right, top, bottom
• When rotated, you can see up to 3 faces at once
• The edges of the cube remain parallel in proper perspective
• Transparency helps you see the structure behind the visible faces

Practice Tips

• Try to visualize the hidden faces before rotating
• Notice how angles change as you rotate
• Pay attention to which edges converge in perspective
• Use this as a reference when drawing boxes, buildings, or rooms

Level 2: Multiple Cubes

Now explore a scene with multiple cubes of different sizes arranged in 3D space. This helps you understand how cubes relate to each other and how size affects perspective.

How to Use

1. Click and drag to rotate the entire scene
2. Observe how different sized cubes appear in perspective
3. Notice how smaller cubes appear further away
4. Study the spatial relationships between cubes

Key Observations

• Size variation helps create depth perception
• Cubes maintain their structural integrity regardless of size
• Position affects how cubes appear in relation to each other
• The main cube (center) serves as an anchor for the composition

Practice Tips

• Try to identify each cube's faces in the complex scene
• Notice how size affects visibility of faces
• Use this as reference for drawing scenes with multiple objects
• Practice isolating individual cubes when drawing complex compositions

Level 3: Cube with Overlapping Shape

Explore how a cube interacts with other shapes in 3D space. The main cube is overlapped with a secondary shape (circle or triangle) that can be randomly changed to study different spatial relationships.

How to Use

1. Click and drag to rotate the scene
2. Click the 🎲 button to randomize the secondary shape
3. Observe how different shapes overlap and intersect with the cube
4. Study how transparency helps visualize the relationships

Key Observations

• Shape interaction creates interesting visual compositions
• Overlap helps understand depth and spatial relationships
• Transparency allows you to see how shapes intersect
• Randomization provides endless practice variations

Practice Tips

• Try to identify which parts of each shape are visible
• Notice how different shapes create different intersection patterns
• Use this as reference for drawing complex compositions
• Practice predicting what the random shape will look like before clicking

Next Steps

Once you're comfortable visualizing the cube, try:

• Drawing cubes from memory at different angles
• Understanding how cubes transform into other rectangular forms
• Applying cube perspective to architectural drawing
