Hey all, I have been working on a process to create 3D sculptural relief’s from photos using ZB. I am having trouble making sure I don’t distort the original image when mapping in PM.
When you use an alpha in PM is there a way to scale it to a specific size and change the aspect ratio? Here is what I am doing, I bring in a photo say 4” x 6” into ZB use PM to map the alpha on to a plane with 5-6 sub patches. I create a relief by scaling the final plane in the z to a very thin relief sculpture of the picture. I export as obj, import into and eventually bring the relief into a CAM program and cnc mill the parts. I end up with a 3-D sculptural relief of the 2d picture. BAM a new business is formed. We are in the process of putting this together. We will be soon up and running at the url www.photosculpts.com and in a store near you.
Anyways the trouble I am having is keeping an exact representation of the original picture distortion free. Because when I do the mapping in PM you have to rescale the picture alpha from it being square to picture size aspect ratio. So when scaling it on a plane of the proper aspect ratio I am never really sure if I am distorting the picture.
SO is there a way to change the aspect ratio of the original alpha ( the picture) to the exact size or pixel count to keep from distorting the picture in either the X or Y. ANY help with this would really be great.
Thanks
