Calculix Data Visualiser using QT
- by Ann
I am doing a project on CalculiX data visualizor,using Qt.I 've to draw the structure and after giving force the displacement should be shawn as variation in color.I chose HSV coloring,but while executing I got an error message:"QColor::from Hsv:HSV parameters out of range".The code is:
DataViz1::DataViz1(QWidget *parent) :
QWidget(parent),
ui(new Ui::DataViz1)
{
DArea = new QGLScreen(this);
DArea-setGeometry(QRect(10,10,700,600));
//TODO This values are feeded by user
dfile="/home/41407/color.txt";//input file with displacement
mfile="/home/41407/mesh21.txt";//input file
nodeId="*NODE";
elId="*ELEMENT";
DataId="displ";
parseMfile();
parseDfile();
DArea->Nodes=Nodes;
DArea->Elements=Elements;
DArea->Data=Data;
DArea->fillColorArray();
//printf("Colr is %d",DArea->pickColor(-11.02,0));fflush(stdout);
ui->setupUi(this);
}
DataViz1::~DataViz1()
{
delete ui;
}

if(line.startsWith(nodeId))//Node block in Mfile

{

}

while(1)
{
