Hi, Looking for a clever idea on how to 'panel' any given geo into discreet units. Ill try to explain.. Basically I want to take a 3d model and divide the surface into different sections, each with a thickness. The sections would build on top or under each other and fit perfectly. There needs to be overlap between the sections / panels. The usage of this is to be able to 3d print a model that is larger than the 3d printer build volume, but instead of simply cutting the object and having the parts show a seam, I would like for the different cuts to be more like panels that overlap.. So a way to think about it is imagine a given 3d model, and 'patches' adhering to the model all over it until they cover it completely. There is some overlap between the patches, and they take the exact point position of the underlying geo (so there is no loss in detail). I then take each patch and extrude it a bit to add thickness. Is there a procedural way to do this? Obviously better if it would give me some control on the overlap of each panel, etc. Hoping that was somewhat clear.. trying to get a visual somewhere will post if I find one.
guache posted a topic in ModelingI use Houdini to design parts for 3D printing. The requirement for 3D printing is manifold geometry ("watertight" models, no single edges, no "T" connections between polys etc). I have a polygonal object, the result of many Boolean operations. From my, human view, it looks "watertight": it's a polygonal shell that encloses a definite region in space, with no holes. But my slicing software (Simplify3D) gives me "non-manifold" verdict, high-lighting in red many of the Boolean'd edges. Is there some way in Houdini (SOP or OTL) to cleanly rebuild a mesh from scratch (based on an existing mesh) and clean it up for 3D printing? For example, turn it into a point cloud, then I, as a human, could provide the software with clues where "inside" and "outside" is (e.g. by creating points and defining them as "inside" and "outside" the model. The SOP or OTL would then rebuild all polys in a way that creates a consistent, clean mesh. I tried the PolyDoctor SOP and turned most of its "Repair" options on, but it didn't do anything useful.
stickman posted a topic in ModelingJust thought I'd drop this as it is very cool, and has a houdini feel to it.
