3D car synthesis

• Astraea Software is researching and developing 3D shape recognition functions using the latest deep learning technology.
• This technology does not use the already popular 2D image identification technology, but directly grasps and identifies the shape from the coordinates and surface information of the 3D shape.
• At the demo site, we are creating a new design by recognizing the three-dimensional shape of the base car and style car.

About 3D car synthesis(display details)
〇Synthesis procedure

• The feature vectors W (base) and W (style) are extracted from the two car bodies (base and style) to be combined using Encoder.
• Create an initial body mesh that will be the skeleton of the new design.
• Adjust the percentage of base / style ratio added to your new design.
• Feature vectors W (base) and W (style) are added to the body mesh using Decoder.
• Perform 5 addition steps to create a new car design.

〇Synthetic notes

• Encoder / Decoder for 3D shape recognition uses an AI model in which a large amount of vehicle body shapes are trained in advance.
• The 5 steps means 5 feature groups unique to the AI ​​model.
• You can create various designs by giving parameters (ratio) to apply the style car to the base car in 5 steps.

About object files

• The file contains only coordinate and surface information, no information indicating the shape type.

3D view adjustment

Base/Style 3D object selection

• Please select a link of Base/Style. When you select a link, it will be displayed in the object view accordingly.

Object view of Base and Style cars

• The 3D object of the selected base / style car is displayed here.
• You can rotate the car by dragging left mouse button and move the car by dragging right mouse button.
• You can zoom in and out on the car with the mouse wheel.

Adjustment of application ratio to base car

• Adjust the ratio of applying the style car to the base car.
• You can adjust all parameters at once by "All Parameters" slider bar.
• You can adjust individually by "Parameter 1" to "Parameter 5" slider bar.
• If the parameter is set to 0% or 100%, a car body with the features of the base car or style car only will be generated.

All parameters

	Parameter１
	Parameter２
	Parameter３
	Parameter４
	Parameter５

Performs base/style car synthesis processing.
Perform base/style car synthesis process collectively.
(The application ratio is gradually increased to 20%, 40%, 60%, 80%, and the synthesis process is performed 4 times.)

Synthesis result

• The combined base / style car 3D object is displayed here.
• You can rotate the car by dragging left mouse button and move the car by dragging right mouse button.
• You can zoom in and out on the car with the mouse wheel.
