示例1: pow
void
Zoom3D::ZoomCamera(const int x, const int y)
{
if (OldY != y)
{
//
// Calculate the zoom factor.
//
double dyf = MotionFactor * (double)(y - OldY) /
(double)(Center[1]);
double zoomFactor = pow((double)1.1, dyf);
//
// Calculate the new parallel scale.
//
VisWindow *vw = proxy;
avtView3D newView3D = vw->GetView3D();
newView3D.imageZoom = newView3D.imageZoom * zoomFactor;
OldX = x;
OldY = y;
vw->SetView3D(newView3D);
}
}示例2: fabs
