## 3D Primitives

### Sphere

```python theme={null}
Sphere(radius=1, resolution=(20, 20), **kwargs)
```

Creates a 3D sphere.

**Parameters:**

* `radius` (float): Sphere radius
* `resolution` (tuple): (u\_res, v\_res) mesh resolution

**Example:**

```python theme={null}
sphere = Sphere(radius=1.5, resolution=(40, 40), color=BLUE)
```

### Cube

```python theme={null}
Cube(side_length=2, **kwargs)
```

### Cone

```python theme={null}
Cone(base_radius=1, height=2, **kwargs)
```

### Cylinder

```python theme={null}
Cylinder(radius=1, height=2, **kwargs)
```

## Surfaces

### Surface

```python theme={null}
Surface(
    func,
    u_range=[-1, 1],
    v_range=[-1, 1],
    resolution=(10, 10),
    **kwargs
)
```

Creates a parametric surface.

**Parameters:**

* `func`: Function (u, v) → \[x, y, z]
* `u_range`: Range for parameter u
* `v_range`: Range for parameter v
* `resolution`: Mesh resolution

**Example:**

```python theme={null}
import numpy as np

surface = Surface(
    lambda u, v: np.array([u, v, u**2 - v**2]),
    u_range=[-2, 2],
    v_range=[-2, 2],
    resolution=(30, 30)
)
```

### ParametricSurface

```python theme={null}
ParametricSurface(func, **kwargs)
```

## 3D Axes

### ThreeDAxes

```python theme={null}
ThreeDAxes(
    x_range=[-6, 6, 1],
    y_range=[-5, 5, 1],
    z_range=[-4, 4, 1],
    **kwargs
)
```
