Useful things for making 3D objects with computers.
ie not sure where else to put these
- Large collection of foldable polyhedra
- Bitmap to vector converter - unlike Inkscape or similar converter, this draws the pixel outlines (as squares.) Also converts to 3D file formats
- DnD characters: http://imgur.com/a/57Ypa
- Free models, mostly structural elements, at Craftsmanspace
Represent 3D objects as points (vertices) and lines (edges.)
Great for computer games, movies, etc. Not so good for mechanical designs- once created, the application (probably) doesn’t know that parts of the object were originally a sphere, cube, etc.
- Doodle3D: online app that allows you to easily take a 2D sketch and create a 3D form.
A true Swiss-army knife of 3D, Video, and game design. Also known for artistic CAM (3D CNC milling- BlenderCAM).
And it’s free!
Deserves it’s own page!
Recalculating the vertices and edges that make up your object. Often needed to make an object usable with physical fabrication.
Stack Overflow discussion
- One of the suggestions is retopoflow, that is available as source & can also be bought (please support the creator if you use it often!)
- instant-meshes - separate app. Has been suggested as precursor before importing a mesh into Fusion360; you can use it to create a clean quad (rather than triangle) based mesh.
- Using GMSH to generate quad mesh geometry
Autodesk products. Solid Works. CAD tools that build up your object as a series of operations on mathematical shapes (cubes, spheres, cylinders, etc). The computer ‘knows’ what ‘makes up’ your object and you can go in and tweak the building blocks, regenerating your object.
You can also convert these objects to meshes by ‘sampling’ the mathematical object. You can control the final resolution of the converted object.
Very friendly, online, place to start for constructive geometry.
Also often the fastest and least likely to fail to do basic boolean modifications of mesh files.
Very popular, and free for many users.
Like ‘pixels’ (picture cells) in bitmap images, but 3D volumes.
Are great for maximum freedom when creating organic forms. Application (probably) has no idea about the tools used to create the shape (e.g. cube here, cylinder there, etc)- unlike solid modelling.
- works with MineCraft worlds
- MagicaVoxel - free voxel editor
- 3DCoat is expensive, and very powerful
poly2vox- command line utility for converting between voxel formats
- kv6toschematic - java converter from kv6 voxel format to Minecraft schematic. Link is to Archive.org mirror.
- Online Voxelizer - converts from various mesh to various voxel formats.
- Structure Synth: “Structure Synth is a cross-platform application for generating 3D structures by specifying a design grammar. Even simple systems may generate surprising and complex structures.”
- Beetle Blocks- Scratch based visual code for creating 3D shapes
- Intro to PythonOCC - create BREP geometry with Python
