Hi,
I have an elevation model and multiple image files (jpeg format). The four
vertex coordinates of each image file are recorded in a text file. So, I wonder
how can I put all these image files on he surface of elevation model with
their vertex coordinates. Now, I can put only one image file
Hi,
I use osgdem to create an IVE model with mercator projection and can load the
model in my OSG program. I want to realize such funciton:
(1) input the WGS84 coordinate (lon, lat) of target point
(2) calculate the elevation (z) of the point from the terrain file
(3) draw a graphic object at

Hi, Shayne.
Thanks for your reply.
What i want to do is converting Lon/Lat coordinate with WGS84 coordinate system
to X/Y coordinate with Mercator coordate system.
How can I program in OSG?
Thank you!
Cheers,
tianyun

Hi,
I am developing an application to display large amount of points which are
moving dynamically. The each point's position, size and color will change
according to a parameter file for every frame.
Using particle system, I can render movement of large amount of points, but I
don't know how
Hi,
I am trying to get the intersection points between an intersection plane and a
terrain using osgUtil::PlaneIntersector。
The code is listed as following:
osg::Plane planeLeft( osg::Vec3(1,0,0), osg::Vec3(0+1,0,0) );//define
an intersetion plane

the file polylines generated then you are best doing this as post process.
The alternatively is to simply write code that isn't sensitive to the
ordering of the polylines.
