QCustom3DVolume along with data

[Ando.Ki]

Hi all,

I'm trying to build a 3D viewer using 2D data array, which is a sort of raw 8-bit gray intensity. (Basically it is a kind of tomographic viewer to see a pile of 2D images.)
The 2D array consists of a number of frames and each frame consists of certain width and height.
At first, I tried to use setTextureData() after building QVector<uchar> data from the raw data,
but it seemed not working.

Next, I tried to import a PNG file several times using setSubTextureData(), in which the PNG file was 8-bit grey and Format_Indexed8 format. This attempt could not give a success, either.

I wonder if there is any specific example for this example. I tried to reuse 3D Volume rendering example, but it was not fit to my case.

Could anyone enlighten me the data format for QCustom3DVolume for 8-bit grey scale?

Thanks.
