qt - How to add 2D surface to a QML Scatter3D

Question

I want to add a 2D surface of a static image to a 3DScatter graph as shown below.

I can achieve this using QCustom3DVolume. However my app uses OpenGL ES and QCustom3DVolume's documentation explicitly says that it does not support OpenGL ES environments.

I have also tried creating a simple cubic obj mesh file, load it using QCustom3DItem and set its textureFile property to my desired image. However there seems to be no way to scale the texture image to fit the item size as shown below.

original image:

mesh file:

# WaveFront *.obj file (generated by Autodesk ATF)

mtllib 5eb607c1-f53f-4cb4-b0b6-7d334249fcd3.mtl

Is there any other way to achieve this?
