When import the stl file very lager such as more than 2GB ,the QMesh will cant load

jimfar

cos the qbytearry size is int and the max size is less than 2.4GB ,when import the file is very lager ,what can i handle it ?

jsulm

@jimfar Are you using 32bit Qt?

jimfar

no 64bit

jimfar

btw the resize of qbytearry is int，

jsulm

@jimfar I don't think you can handle more than 2GB with QByteArray. You will need to do it differently. Use char* or maybe memory mapped IO (http://doc.qt.io/qt-5/qfiledevice.html#map).

jimfar

the problem is the QBuffer need QByteArray,and i will put the QBuffer into QAttribute ,so i can constuct the QGeometry

i use these api to load my customized mesh parsed from a stl file
