Hi. I have successfully used view distance ranges in Perspective View to make visual objects appear or disappear to show the level of detail that I desire.
I have not been able to figure out how to do it in Ortho mode though, with the magnification option. Can you please give me some directions?
Are you changing these values on the OnDraw" Trigger? the notes for this are given when you click the code editor when using "Hide shape and contents at a distance" they read:
A higher "View magnification" value decreases the distance at which the shape becomes hidden in the Orthographic View" A lower "View distance" value decreases the distance at which the shape becomes hidden in the Perspective View
@Joshua S I am achieving this (watch attached video): https://youtu.be/TNaf5nMayy8
By usiing this code:
if ( (getnodenum(viewmagnification(view)) > viewmag ||
getnodenum(viewprojectiontype(view)) == 0) &&
(distfromviewpoint(current, view) < 8490 && distfromviewpoint(current, view) > 6500)) {
switch_hidecontents(current,0); // show the contents
if (getobjectshapeindex(current)==0) // if the shape is hidden
setobjectshapeindex(current,getshapeindex(gets(shape(current)))); // show the shape
for (int r=1; r<=content(drawsurrogate(current)); r++) {
treenode obj = rank(drawsurrogate(current),r);
switch_hidecontents(obj,0); // show the contents
if (getobjectshapeindex(obj)==0) // if the shape is hidden
setobjectshapeindex(obj,getshapeindex(gets(shape(obj)))); // show the shape
}
return 0; // default draw code
} else {
switch_hidecontents(current,1); // hide the contents
setobjectshapeindex(current,0); // hide the shape
for (int r=1; r<=content(drawsurrogate(current)); r++) {
treenode obj = rank(drawsurrogate(current),r);
switch_hidecontents(obj,1); // hide the contents
setobjectshapeindex(obj,0); // hide the shape
}<br>
I understand how it works in perspective mode but not in ortho. Is it the same principle?
It works in the same manner. I edited the code:
double ViewFarClip= 12;
double ViewNearClip=70;
print(getnodenum(viewmagnification(view)));
if (getnodenum(viewmagnification(view))> ViewNearClip && getnodenum(viewmagnification(view))<ViewFarClip) {
//Draw Cities
} else {
// Don't Draw Cities
}
this does what your perspective zoom does.
@Joshua S Printing the magnification really helped, as it works differently in ortho mode. As you get farther away the number gets smaller. Now it's working really good and it looks perfect.
