Hi
I would like to create a mesh from a set of points (eg in the .geo file attached). The data in the file represent topography, so the results would ideally look like a earth like surface.

I have tried “triangulate2D” which almost does it but loses all the z data (eg makes it into a 2D plain) and there are other operations that look like they have potential but don't quiet get there, such as polyloft, skin, isoOffset…..

The reason i want the get a surface is to map a image to the mesh, maybe there is a way to map the image without a mesh eg directly on the point and it looks like a mesh?

Any help or ideas would be greatly appreciated!

Use the Triangulate SOP then use the Point SOP to copy the Z information back in.

thanks for the example Wolfwood… but can you tell me why the “TY2” works? how for example can you acess any variable in any point SOP?

AND a big thanks to Ben… haven't read it all yet but there is some great stuff in there! cheers

$TX2, $TY2, $TZ2 are local variables for the second input. Check the help for the Point SOP, there are a ton of variables available for abuse.

$TY2 in pointSOP means: for each point position (of the first imput) assign a Y position of the second imput.

You can store any value in an custom attribute (using attributecreateSOP) Then you can create “Local variable” name which is exacly the same thing as $TY. You can recall values stored in attributes using local variable names.

hope that helps
