Set model parameters adjustment during try-on preview
In some special situations, there are a lot of factors will impact the experience of try-on. Hence, we introduced the parameters adjustment function to help our users get a better Try-On experience.
We can take the real try-on experience as a reference based on the current style or the same type shoes. For example:
The pointed shoes will be longer than the toe position
The sole of high heel is lower than that of the foot
...
What parameters can be adjusted for perfect effects and how to do it? Please read the below article .
Exporting from other applications
First of all, it is highly recommended that you properly export the shoes model according to our standard posture to be compatible with our platform and components.
The definition of the XYZ axis is the basis for parameters settings. As shown in the picture above, after the model is correctly exported, the three-dimensional coordinates are defined as follows:
The X-axis is the red coordinate that represents the width of the shoes from left to right
The Y-axis is the blue coordinate that represents the length from shoes toe cap to heel
The Z-axis is the green coordinate that represents the height from vamp to sole
Detailed Instructions for Parameters
Next, we will explain in detail which parameters can be edited and the corresponding adjustment effects.
Adjust the position
Respectively take the X, Y, and Z axes as horizontal lines and move along them.
Below is the position of moving the X-axis:
The following shows the position of moving the Y-axis:
Here is position of moving the Z-axis:
Adjust the rotation
Respectively take the X, Y, and Z axes as horizontal lines and rotate around them.
Below is the angle of rotation of the X-axis:
The following is the angle of rotation of the Y-axis:
Here is the angle of rotation of the z-axis:
Scale
As mentioned above, the X, Y, and Z axes represent width, length, and height, respectively, and then adjust them as needed.
The below shows the adjustment of X-axis length：
The following is the rotation of Y-axis length:
Below is the rotation of Z-axis length：
You can adjust the width, length and height synchronously, as shown in the button below. If adjusted separately, be sure to ensure a normal shoe shape.
Please kindly note that the adjusted data is equal to the current data multiplied by (1+ Step value), which means that when resizing, it scales based on the current data, rather than simply increasing or subtracting it.
These are the three parameters that can be adjusted. You can adjust a certain axis of a parameter according to the actual situation.
For example, the try-on effect of this sneaker is shown in the image below, and you can adjust the following parameters for better effects.
Increase the size of the shoes so that it covers the foot
Increase the X-axis rotation value so that the 3D model is at the same level as the shoes you are wearing
Reduce the Z-axis height so that the sole of the model is at the same level as that of your real shoes
Here is an example of parameter adjustment. You can optimize the try-on effect based on your actual situation.
Adjustment Object
When setting parameters, the shoes model and masks are both the adjustment objects and share the above adjustment parameters. The shoes model is selected by default.
Shoes model
The program will automatically mirror the parameters of the left and right shoes so you don't have to distinguish between them.
Mask
In fact, when we view the shoes we're wearing, there are certain angles where we can't see. A mask works on this principle, meaning it simulates a situation in which a shoe might be obscured during the virtual try-on.
As shown in the picture above, the insole and heel can't be seen from the current perspective, so the shoes in AR should also be simulated in this way.
Before adjusting, you first need to select the adjustment object as “Mask”. When selected, a new button will prompt you to switch between “Show the Mask” or “Hide the Mask”.
The corresponding effects are as follows：
Then adjust the mask parameters step by step according to the actual situation. Please note that the shoes should be intact without any damage during adjusting, and the obscuration needs to be simulated as much as possible.
We prefer to display the mask first, then hide the mask and check the effect after the parameters adjustment. You can do it according to your preference.
Step-size Unit
The step value is the unit in which the limit can be adjusted accordingly by clicking on the "+" or "-" once. The larger the step value, the greater the limit of adjustment.
Hope this tutorial can help you easily and quickly adjust a perfect AR try-on effect.
