How do make a 3d model of this?
-
Hello pros,
I found this NASA site where I can download topography images. Iยดve seen these black and white images before and I heard they can be (or are ment to be) used to create 3d topography models. The problem is that I donยดt know how to do that, once I have the images. Can someone help me out?

Maybe Bitmap to Mesh by Thomthom if you want stay inside Sketchup but reduce the size first!

You need to displace a subdivided mesh so the image can act as the displacement map to raise and lower the mesh.
Here's an example with only a single area acting as a displacement map. The mesh is at 0.7million vertices to get anything reasonable for presenting.
I would think using this technique on the full resolution would require you traveling to CERN and making use of the Hadron Collider to run SU.

In SU it becomes unusable at 0.5million vertices.

Actually when I saved the file as a .skp it was 64mb in size.
I imagine the full file would run into gigabytes.

@ Rich : With what have you made your displacement Map?

I used Blender....

I love it when you talk dirty.

I should start charging

I have an Alienware computer, I got this.

Do you have access to it...??
