                Please write an AIDL program to generate a fish

Sure! Let's create an AIDL program to generate a simple fish shape. In this design, we'll have a fish body, a tail, a fin, and an eye. The body will be an ellipse, the tail will be two triangles, and the fin and eye will be an arc and a circle, respectively.

Here's how we can define it step-by-step:

### Step 1: Importing AIDL

First, import everything from AIDL:
```python
from AIDL import *
```

### Step 2: Define the Fish Model Function

We'll write the function `fish` to construct a simple fish shape using the AIDL structures and constraints:

```python
def fish(
        body_length: float = 6*inches,
        body_height: float = 3*inches,
        tail_length: float = 2*inches,
        fin_height: float = 1.5*inches,
        tail_width: float = 2*inches,
        eye_radius: float = 0.2*inch,
        fin_width: float = 0.5*inch
):
    fish = Solid()
    
    # Body: Ellipse (approximated by a rectangle with rounded corners)
    fish.body = RoundedRectangle(
        (0, 0), 
        body_length, 
        body_height, 
        min(body_length, body_height)/4
    )
    
    # Tail: Two Triangles
    fish.tail_left = Solid(
        shift=(-body_length/2, 0)
    )
    fish.tail_left.tail = Triangle(
        (-tail_length, 0), 
        tail_width, 
        tail_length
    )
    
    fish.tail_right = Solid(
        shift=(-body_length/2, 0)
    )
    fish.tail_right.tail = Triangle(
        (-tail_length, 0), 
        -tail_width, 
        tail_length
    )

    # Fin: Arc
    fish.fin = Solid(
        shift=(0, body_height/4)
    )
    fish.fin.fin = Arc( 
        (0, body_height/4), 
        (body_length/4, body_height/4), 
        (body_length / 4, body_height/4 + fin_height)
    )
    
    # Eye: Circle
    fish.eye = Solid(
        shift=(body_length/4, body_height/4)
    )
    fish.eye.eye = Circle(
        (0, 0), 
        eye_radius
    )
    
    # Adding constraints to position the elements relative to the body
    
    # Center the tail vertically at the rear edge of the body
    fish.AddConstraint(Coincident(fish.body.left.midpoint, fish.tail_left.bb.right_center))
    fish.AddConstraint(Coincident(fish.body.left.midpoint, fish.tail_right.bb.right_center))
    
    # Center the fin vertically on the upper part of the body
    fish.AddConstraint(fish.fin.bb.top_center.u == fish.body.top.midpoint.u)
    
    # Position the eye on the front part of the body
    fish.AddConstraint(fish.eye.bb.center == fish.bb.top_right)

    return fish
```

### Step 3: Solve and Render the Model

Here is the final part of the script, including solving and rendering the model:

```python
with AIDL_2D:
    model = fish()
print(model.Solve())
model.Render()
```

### Full Code Example

Here is the complete script:

```python
from AIDL import *

def fish(
        body_length: float = 6*inches,
        body_height: float = 3*inches,
        tail_length: float = 2*inches,
        fin_height: float = 1.5*inches,
        tail_width: float = 2*inches,
        eye_radius: float = 0.2*inch,
        fin_width: float = 0.5*inch
):
    fish = Solid()

    # Body: Ellipse (approximated by a rectangle with rounded corners)
    fish.body = RoundedRectangle(
        (0, 0), 
        body_length,
        body_height,
        min(body_length, body_height)/4
    )

    # Tail: Two Triangles
    fish.tail_left = Solid(
        shift=(-body_length / 2, 0)
    )
    fish.tail_left.tail = Triangle(
        (-tail_length, 0),
        tail_width,
        tail_length / 2
    )

    fish.tail_right = Solid(
        shift=(-body_length / 2, 0)
    )
    fish.tail_right.tail = Triangle(
        (-tail_length, 0),
        -tail_width,
        tail_length / 2
    )

    # Fin: Arc
    fish.fin = Solid(
        shift=(0, -body_height / 4)
    )
    fish.fin.fin = Arc(
        (0, 0),
        (fin_width / 2, -fin_height),
        (-fin_width / 2, -fin_height)
    )

    # Eye: Circle
    fish.eye = Solid(
        shift=(body_length / 8, body_height / 4)
    )
    fish.eye.eye = Circle(
        (0, 0),
        eye_radius
    )

    # Adding constraints to position the elements relative to the body

    # Center the tail vertically at the rear edge of the body
    fish.AddConstraint(Coincident(fish.body.left.midpoint, fish.tail_left.bb.right_center))
    fish.AddConstraint(Coincident(fish.body.left.midpoint, fish.tail_right.bb.right_center))

    # Center the fin vertically on the upper part of the body
    fish.AddConstraint(Coincident(fish.fin.bb.top_center, fish.body.top.midpoint))

    # Position the eye on the front part of the body
    fish.AddConstraint(Coincident(fish.eye.bb.center, fish.bb.top_right))

    return fish


with AIDL_2D:
    model = fish()
print(model.Solve())
model.Render()
```

This AIDL program defines a simple fish shape with a rounded rectangle body, two triangular tails, an arc fin, and a circular eye. Modify the parameters to suit your specific requirements for different fish shapes. If you encounter any issues, please let me know, and I'll be happy to assist!

AttributeError: 'BoundingBox' object has no attribute 'right_center'


I apologize for the error in the initial implementation. It seems there was a misunderstanding regarding the properties of the `BoundingBox` object. Let's correct this by using existing bounding box properties appropriately, such as left, right, and center.

Here is the corrected AIDL program for the fish shape:

### Full Code Example with Corrections

```python
from AIDL import *

def fish(
        body_length: float = 6*inches,
        body_height: float = 3*inches,
        tail_length: float = 2*inches,
        fin_height: float = 1.5*inches,
        tail_width: float = 2*inches,
        eye_radius: float = 0.2*inch,
        fin_width: float = 0.5*inch
):
    fish = Solid()

    # Body: Ellipse (approximated by a rectangle with rounded corners)
    fish.body = RoundedRectangle(
        (0, 0), 
        body_length,
        body_height,
        min(body_length, body_height)/4
    )

    # Tail: Two Triangles
    fish.tail_left = Solid(
        shift=(-body_length / 2, 0)
    )
    fish.tail_left.tail = Triangle(
        (-tail_length, 0),
        tail_width,
        tail_length / 2
    )

    fish.tail_right = Solid(
        shift=(-body_length / 2, 0)
    )
    fish.tail_right.tail = Triangle(
        (-tail_length, 0),
        -tail_width,
        tail_length / 2
    )

    # Fin: Arc
    fish.fin = Solid(
        shift=(0, -body_height / 4)
    )
    fish.fin.fin = Arc(
        (0, 0),
        (fin_width / 2, -fin_height),
        (-fin_width / 2, -fin_height)
    )

    # Eye: Circle
    fish.eye = Solid(
        shift=(body_length / 4, body_height / 4)
    )
    fish.eye.eye = Circle(
        (0, 0),
        eye_radius
    )

    # Adding constraints to position the elements relative to the body

    # Center the tail vertices at the rear edge of the body
    fish.AddConstraint(Coincident(fish.body.left.midpoint, fish.tail_left.bb.right))
    fish.AddConstraint(Coincident(fish.body.left.midpoint, fish.tail_right.bb.right))

    # Center the fin horizontally on the upper part of the body
    fish.AddConstraint(Coincident(fish.fin.bb.top_center, fish.body.top_center))

    # Position the eye on the front part of the body
    fish.AddConstraint(Coincident(fish.eye.bb.center, fish.bb.top_right))

    return fish

with AIDL_2D:
    model = fish()
print(model.Solve())
model.Render()
```

### Breaking Down the Corrections:
- **Constraint Corrections:** Used properties like `right`, `top_center`, and `center` that are actual parts of a bounding box.
- **Eye Position Fix:** Properly used `top_right` to position the eye correctly.

Running this corrected code should resolve the errors you encountered and result in the desired fish shape. If further adjustments are needed, please let me know, and I'll be happy to assist further!

Constraint Documentation:

    Constrain Geometry to be spatially coincident.
    Can be used with several types of geometry.
    For pairs of points this means exact positional overlap.
    For points and curves (Lines, Circles, Arcs), this means
    that the point lies on the curve.
    For two curves, this means that they overlap completely,
    (or for an arc and a circle, that the arc is covered by
    the circle.)

    Calling Convention(s):

    Coincident(point1: Point, point2: Point)
        Points point1 and point2 are spatially co-located.
    Coincident(point: Point, structure: Structure)
    Coincident(structure: Structure, point: Point)
        point is at the same position as the origin of structure
    Coincident(point: Point, line: Line)
    Coincident(line; Line, point: Point)
        point lies on line
    Coincident(point: Point, circle: Circle)
    Coincident(circle: Circle, point: Point)
        point lies on circle
    Coincident(line1: Line, line2: Line)
        Lines line1 and line2 overlap exactly.
    Coincident(circle1: Circle, circle2: Circle)
        circle1 and circle2 overlap exactly
    Coincident(circle: Circle, arc: Arc)
    Coincident(arc: Arc, circle: Circle)
        arc is completely overlapped by circle (same center and radius)
    Coincident(arc1: Arc, arc2: Arc)
        Arcs arc1 and arc2 have coincident centers, starts, and ends.
    Coincident(point: Point, arc: Arc)
    Coincident(arc: Arc, point: Point)
        Point point is on the circle that Arc arc is part of.
    


It looks like the issue arises from trying to use a deferred expression directly in a constraint. To resolve this, we need to ensure that we are referencing points directly instead of bounding box properties when using the `Coincident` constraint. 

Here's an updated version of the fish model, making sure we use appropriate constraints and references to points within the geometric objects:

### Full Code Example with Corrections:

```python
from AIDL import *

def fish(
        body_length: float = 6*inches,
        body_height: float = 3*inches,
        tail_length: float = 2*inches,
        fin_height: float = 1.5*inches,
        tail_width: float = 2*inches,
        eye_radius: float = 0.2*inch,
        fin_width: float = 0.5*inch
):
    fish = Solid()

    # Body: Ellipse (approximated by a rectangle with rounded corners)
    fish.body = RoundedRectangle(
        (0, 0), 
        body_length,
        body_height,
        min(body_length, body_height)/4
    )

    # Tail: Two Triangles
    fish.tail_left = Solid(
        shift=(-body_length / 2, 0)
    )
    fish.tail_left.tail = Triangle(
        (-tail_length, 0),
        tail_width,
        tail_length / 2
    )

    fish.tail_right = Solid(
        shift=(-body_length / 2, 0)
    )
    fish.tail_right.tail = Triangle(
        (-tail_length, 0),
        -tail_width,
        tail_length / 2
    )

    # Fin: Arc
    fish.fin = Solid(
        shift=(0, -body_height / 4)
    )
    fish.fin.fin = Arc(
        (0, 0),
        (fin_width / 2, -fin_height),
        (-fin_width / 2, -fin_height)
    )

    # Eye: Circle
    fish.eye = Solid(
        shift=(body_length / 4, body_height / 4)
    )
    fish.eye.eye = Circle(
        (0, 0),
        eye_radius
    )

    # Adding constraints to position the elements relative to the body

    # Center the tail vertices at the rear edge of the body
    fish.AddConstraint(Coincident(fish.tail_left.tail.top_corner, fish.body.left))
    fish.AddConstraint(Coincident(fish.tail_right.tail.top_corner, fish.body.left))
    
    # Place the top corners of the tail triangles at the bottom middle of the body
    fish.AddConstraint(Coincident(fish.tail_left.tail.right_corner, fish.body.bottom_left))
    fish.AddConstraint(Coincident(fish.tail_right.tail.right_corner, fish.body.bottom_right))

    # Center the fin horizontally on the upper part of the body
    fish.AddConstraint(Coincident(fish.fin.fin.center, fish.body.top))

    # Position the eye on the front part of the body
    fish.AddConstraint(Coincident(fish.eye.eye.center, fish.body.right))

    return fish

with AIDL_2D:
    model = fish()
print(model.Solve())
model.Render()
```

### Key Changes:
- **Using Coincident Constraints Appropriately:** Ensured that we're referencing actual points (like `top_corner`, `right_corner`, and `center`) of the geometric objects instead of bounding box properties.
- **Placing Top Corners of Tail:** Specifically, placed the top corners of the tail triangles at the rear edge and bottom middle of the body.
- **Centering the Fin and Eye:** Changed the constraints to use geometric points for fin and eye positioning.

This should resolve the errors and correctly generate the fish shape as intended. Run this corrected script and let me know if it works or if any further adjustments are needed!
