I just want to set the value of some complex points via dragging locators
around. Then I want to set the corresponding positions of 3D points, with z
values adjustable via sliders.
Do I have do everything from within a single DynamicModule to do this? I'd
also like to preserve their values between sessions. Is DynamicModule the
recommended way to do this also?
The Dynamic[p] on the outside doesn't get updated via the Dynamic[p] within
DynamicModule.
Dynamic[p]
DynamicModule[
{p = {0.5, 0.5}},
{
Graphics[
Locator[Dynamic[p]],
PlotRange -> 2
],
Dynamic[p]
}
]
