digital elevation model
 

I have digital elevation model of some place and corresponding raster image. Both dem and image is in jpg format.
How to drape this in vizard?

i want to generate terrain using height maps basically

I don't know of a particular workflow but the 3D models page lists the formats that Vizard has support and partial support for. If you can import your data into modeling software then you maybe able to export to a supported format and load in Vizard.

Hello jeff,
thanks for responding.

Suppose I am having x,y,z ; z as height with me.

Now , I want to plot this information as a surface plot in 3D , how to do that in vizard.

I want to create 3d surface/ terrain using height information and afterwards want to add texture to this.

Please , help me how to do this.

In matplotlib i am able to do this using plot_surface.
In openGL , same can be implemented using vertex and shaders

Hello Jeff and all,

please respond to my query?

The best solution would be to create the model in modeling software and export for Vizard. In Vizard, you can create on-the-fly objects and texture them but I'm not sure how well that would work for a large scale terrain.

Jeff,

Is there a difference in terms of rendering performance for an imported model and on-the-fly created model?

Take into consideration large models not a simple cube or line.

Using modeling software it would be easier to apply optimizations that would affect performance. See the optimizations page and the section on polygon budgets.
