Detailed Description

QOpenGLTexture makes it easy to work with OpenGL textures and the myriad features and targets that they offer depending upon the capabilities of your OpenGL implementation.

The typical usage pattern for QOpenGLTexture is

Instantiate the object specifying the texture target type
Set properties that affect the storage requirements e.g. storage format, dimensions
Allocate the server-side storage
Optionally upload pixel data
Optionally set any additional properties e.g. filtering and border options
Render with texture or render to texture

In the common case of simply using a QImage as the source of texture pixel data most of the above steps are performed automatically.

 // Prepare texture
 QOpenGLTexture *texture = new QOpenGLTexture(QImage(fileName).mirrored());
 texture->setMinificationFilter(QOpenGLTexture::LinearMipMapLinear);
 texture->setMagnificationFilter(QOpenGLTexture::Linear);
 ...
 // Render with texture
 texture->bind();
 glDrawArrays(...);

Note that the QImage is mirrored vertically to account for the fact that OpenGL and QImage use opposite directions for the y axis. Another option would be to transform your texture coordinates.
