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

Click and drag on the cube above to rotate it
Observe how the faces change as you rotate
Notice which faces are visible from different angles
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

Click and drag to rotate the entire scene
Observe how different sized cubes appear in perspective
Notice how smaller cubes appear further away
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

Click and drag to rotate the scene
Click the 🎲 button to randomize the secondary shape
Observe how different shapes overlap and intersect with the cube
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
