FYI,

New tool in ViaCAD 10 PowerPack to convert bitmaps into 3D meshes.

I've used a freeware heightfield creator called ZSurf4. It produces a NURB surface from greyscale bitmaps, so 255 graduations. It'll be interesting to see your take on it when the vid's available, Tim.

I originally produced a NURB, but it was frequently wobbly.

The resultant mesh is mostly a smooth quad and can produce nice SubD to NURB results.

It also produces a scaled height map from 255 graduations. If the original image is not a grayscale, it converts the RGB to a grayscale value and then mapped to a height value.

Just upgraded to ViaCAD10 + PowerPack10. I cannot find the 'Heightmap to 3D Mesh' feature. The only option under 'PowerPack->Mesh Tools' is 'UNDO Heightmap'. Selecting this option and then an image just causes endless busy cursor and I must force close ViaCAD Pro via task manager. (I did wait 10 minutes for it to complete). Seems many other tools shown in the videos are also not present(unroll, mesh to solid, etc). Am I just missing something?

>>UNDO Heightmap
Checking...

>> unroll

This is in the Draw : Unroll Surface

Mesh to Analytic, SubD to NURB are in PowerPack Pro.

Would it be possible for you to post or private email me the file that is that is not converting using the Heightmap tool?

Hello Tim,

Thanks for the quick response.
I did finally get the heightmap tool to convert the image. I just had to wait longer.
Though it would be a simple image to convert but once I saw the mesh I realized the picture had a lot of subtle noise.
I've attached the image anyway.

Found the unroll... Thank you.

Not sure how to feel about the other tools being in a PowerPack 'Pro'.
There was no 'Pro' option available when I upgraded.
I decided to upgrade to v10 after I watched the 'HeightMap to 3D Mesh' video at https://www.youtube.com/watch?v=EiRIkJT0zjI
which has the description: 'Using PowerPack 10, we demonstrate converting several bitmaps into 3D meshes.'
Guess I just assumed I would get everything shown in the videos 'PowerPack' menu. Probably my bad.
Really would have liked the 'mesh to solid' feature though as I frequently struggle with 'healing' and 'limits' when trying to stitch or skin downloaded stl files so I can mod them as solids.
Anyway, thanks again for the response.

DT

I made some changes last night and this is much faster.

I also updated the menu to correctly say HeightMap to Mesh instead of Undo HeightMap. This was an error introduced localizing for another language. Thanks for the heads up.

I'll private email you a link to a new build if you would like to confirm.

Tim

Wow, now that's what I call product support! Awesome!
I would love to try the new build. Not sure how to confirm..(maybe I just did?)
If you need info from me let me know.
Thanks again for the responsiveness. It's uncommon and greatly appreciated.
