turn: 1
modality: image
input: Generate an object that looks very similar to a viola, but: 1. Unlike a viola, it does not have the viola's typical larger size and deeper body; 2. Instead, it has the violin's distinctive, smaller, more slender body shape and four tuning pegs on a scroll-shaped pegbox.
output: evaluation_points: 1. The object's overall silhouette is indeed easily confused with a viola.

2. The image clearly does NOT show the viola's larger size and deeper body.

3. The image clearly shows the violin's smaller, slender body shape and four tuning pegs on a scroll-shaped pegbox.

turn: 2
modality: image
input: Based on the previous context, further distinguish this object through its physical properties: 1. It has a unique, slender and graceful hourglass-shaped contour; 2. It is typically made of spruce for the top and maple for the back, sides, and neck.
output: evaluation_points: 1. Maintains the previously established distinguishing features: it has the violin's smaller, slender body shape and four tuning pegs on a scroll-shaped pegbox (as required in Turn 1), and it lacks the viola's typical larger size and deeper body (as required in Turn 1).

2. The object's contour and proportions conform to the described slender, graceful hourglass shape.

3. The object's material rendering is correct, with a light-colored wood (spruce) for the top and a darker wood (maple) for the back, sides, and neck.

turn: 3
modality: image
input: Based on the previous context, add this object's proprietary scenario feature: This object is specifically used for playing in a standard symphony orchestra, in a scenario where a cello cannot be used due to its size and playing position.
output: evaluation_points: 1. Maintains all physical features from the previous descriptions: the violin's smaller, slender body shape and four tuning pegs (Turn 1), the slender and graceful hourglass-shaped contour (Turn 2), and the material composition of spruce top and maple back/sides/neck (Turn 2).

2. The background or the object's state suggests the scenario of a standard symphony orchestra (e.g., on a music stand, in a concert hall setting, or held by a musician in a typical violin playing posture).

3. The overall visual effect clearly points to a violin, excluding the possibility of it being a cello (which is much larger and played between the knees).

turn: 4
modality: text
input: Based on all the previous prompt steps and the final image you generated, please select which of the following items you have generated (output the selected option directly):
Options:
A. Viola
B. Violin
C. Cello
D. Mandolin
E. None of the above.
output: answer: B

turn: 5
modality: image
input: Based on the previous prompts and the image you generated, now modify this object into an electric violin. Please keep its appearance features (such as color, pattern) largely unchanged while updating the necessary components to fit the characteristics of this variant.
output: evaluation_points: 1. The item's color and wood grain pattern remain largely consistent with the original acoustic version (as depicted in Turn 3 output image).

2. The core features of the violin (the basic body shape, neck, and scroll) are retained.

3. The image shows new or modified key structural components that fit an electric violin, such as a solid body (or a body with cutouts instead of traditional f-holes), pickups mounted on the body, and an output jack for a cable.

turn: 6
modality: text
input: Comparing the variant version you drew to the original item, what is the biggest physical structural change made to enable the variant's function?
Options:
A. The shape of the scroll on the pegbox
B. The replacement of the hollow wooden body with a solid body (or a body with electronic pickups)
C. The type of wood used for the neck
D. The number of strings
E. None of the above.
output: answer: B
