turn: 1
modality: image
input: Please generate the main body of an object (do not generate the complete object, only the main body as requested): 1. This main body appears as a solid, elongated wooden plank with a curved, contoured shape; 2. It provides the foundational support and structure for the entire object.
output: evaluation_points: 1. The image contains only the main body/body of the object, with no complete object or other unmentioned parts present.

2. The shape and material of the main body conform to the description of a solid, elongated wooden plank with a curved, contoured shape.

3. The composition is centered, leaving space for subsequent component additions.

turn: 2
modality: image
input: Based on the previous image, connect/add a second component to the main body: 1. This component is a long, thin neck with metal frets embedded along its length; 2. It is connected to the main body via a seamless joint, typically a glued or bolted neck joint.
output: evaluation_points: 1. The form of the main body/body part remains unchanged.

2. The new component (the neck with frets) has been added, and its appearance matches the description.

3. The connection position and method between the neck and the main body conform to the description of a seamless, glued/bolted neck joint.

4. No parts other than the main body and the neck component are generated.

turn: 3
modality: image
input: Complete the assembly of this object by adding the final detail component: 1. Add six tuning pegs/machine heads mounted on the headstock at the end of the neck; 2. This part allows the user to perform the specific interactive operation of tightening or loosening the strings to adjust their pitch.
output: evaluation_points: 1. The main body and the neck component (component B) from the previous two rounds remain unchanged.

2. The tuning pegs/machine heads (component C) appear in the image, with clear details.

3. The overall object form is complete, possessing the possibility for the described string-tuning interaction.

turn: 4
modality: text
input: Based on all the previous prompt steps and the final image you generated, please select which item you have generated (output the chosen option directly):
Options:
A. Electric Guitar
B. Acoustic Guitar
C. Bass Guitar
D. Violin
E. None of the above.
output: answer: A

turn: 5
modality: image
input: Based on the previous prompts and the image you generated, now modify this object into a seven-string electric guitar. Please update the necessary components to fit this variant's features while keeping its visual characteristics (like color, patterns) largely unchanged.
output: evaluation_points: 1. The item's color and patterns in the image remain largely consistent with the original version (the electric guitar generated in Turn 3).

2. The core features of the electric guitar (solid body, neck, headstock) are retained in the image.

3. The image adds or modifies the key structural component that fits the 'seven-string' variant, specifically a wider neck and headstock to accommodate the extra string and tuning peg.

turn: 6
modality: text
input: Comparing the variant version you drew to the original item, what is the biggest physical structural change made to achieve the variant's function?
Options:
A. Adding an extra pickup for more sound options.
B. Widening the neck and headstock to fit a seventh string and tuning peg.
C. Changing the body shape to a double-cutaway design.
D. Replacing the bridge with a tremolo system.
E. None of the above.
output: answer: B
