Creating Organic Sculptures with Kangaroo for Bronze Casting

I am trying to create a organic sculpture as the photos above with Kangaroo but I would ask you guys for a better workflow or suggestions. the size is ca 2,5 meter long and is for bronze casting. It will be 6mm thick bronze skin. Idea was to draw different versions of this one and can calculate the amount of Bronze needed for the casting. Is there possible to create this in GH as its needed to be hollow with a 6mm thick surface?


you may just want to use a .3DM scanner, you can get one on your phone pretty easily and then just size it to IRL, not really much you can do unless you wanna write a whole lot of script. At least, if you just want to measure it.

It would probably be easier to explore SubD modelling for this kind of shape but I could see how you could maybe do this kind of thing by creating a coarse mesh representing the basic shape and then subdividing that with tools in Weaverbird for example.

Do you need to model the surface texture or just the general surface topology and shape?

Is the main purpose of modelling this in CAD to get a better estimate of the amount of bronze required or are you looking to automatically generate random variations?

It reminded me of a model of a molar tooth I did once… Starting with a coarse mesh that is then subdivided with Weaverbird…

You could define “legs” with varying radii along their lengths and a hull in the centre where they meet then subdivide and smooth the result. The Cocoon plugin and Dendro might offer ways of generating these organic shapes too.

Its really hard to give you an answer without knowing more about what you are doing.

I’ve attached the tooth file… (39.3 KB)

The model I need just for the shape and to get a close estimate of the amount of bronze required. The surface topology is not important.

Like I say I am new in kangaroo. was thinking that maybe a way to do it
is trough creating 2 surfaces that are controlled separately by kangaroo kind a top and bottom surface then we extrude them with 6mm and combine… but I am not sure how.

I will definitely take a look att the molar tooth

If you work in meshes then there are MeshThicken components which can give you the 6mm skin thickness.

I think the whole thing revolves mainly around how much your actual model is close in detail to the real 1:1 scale installation you want to accomplish

if your model is just a sketch of the volume, sort-of the general shape of your final installation -but still under definition-, then I would go for redrawing it in Rhino using SubDs (or any other method, but I 'd definitely go with SubDs) using several pictures of your model taken from well-thought angles as background-image-references in order to have a clear “sketeleton” to follow and nice relative proportions

on the other side, if you consider your current model a small-scale “perfect representation” of the final installation (as if you could even use a pantograph to scale it up to finel size, exaclty like it is now) then in this case I would definitely go for a 3D scan service
