Set TextureData to a Texture2D or Texture3D in Qt3D

[Abolfazl]

Hi everyone,
In all Qt examples, the Texture2D gets a TextureImage with a source to display an image in scene3D. But I was wondering if it is possible to create an RGBAformat array and set it to a Texture2D?
Additionally, I generated an array using the following code in javascript and set it to the data of a Texture2D, but it does not show anything.

                                var array = new Uint8Array(400 * 400 * 4);
                                for(var i=0; i< 400 * 400; i++){
                                    // RGB from 0 to 255
                                    array[4*i] = array[4*i + 1] = array[4*i + 2] = 255;
                                    // OPACITY
                                    array[4*i + 3] = 255;
                                }
                                return array

How I can fix this issue?
Thank you.

It's been a long time since I used OpenGL.
OpenGL version 1.1 to 2.1 handle power of 2 textures.
I think it is with GL 3.0 that non pow-2 textures work. I think you have to explicitly create a GL 3.0 or above context. But I could be wrong.

Also, try making a 256 x 256 or 256 x 512 or 512 x 512 texture.
