Voxels versus Triangles
We’ve been studying the size of voxel versus triangle models recently. For really complex models we knew that the file size for voxels would be smaller. As you approach one triangle per voxel you end up using significantly more space … Continue reading
Image Lathe – Variant
It’s been brought to my attention that our first Image Lathe example exhibited a great flaw. It seems some people think a Vase should be able to hold water! Now around the 3D printing world we talk about water-tight meshes … Continue reading
Image Lathe – Aspect Ratio
One important issue when using images for making objects is getting the aspect ratio correct. You can somewhat ignore this at the beginning but eventually you’ll start asking why straight lines are off and how to get the exact wall … Continue reading
Image Lathe
Let’s start with the good stuff first. Here is a 3D print of a new ShapeJS creator called the Image Lathe. This was printed at Shapeways in Black Glossy Ceramics for $25. The basic premise of the creator is to … Continue reading
Journey from Twist to Spring to a new Creator
This post is filled with new ShapeJS features, twist and turns in development and the birth of a new creator. It all started with some prototyping work for this years art project. We’ve been playing with some triple helix designs. … Continue reading
Hollow Out Example
We have a new version of ShapeJS deployed that makes it easy to write a hollow out routine. This allows you to take a solid object and turn it into a shell of specified thickness. Pull up the attached script … Continue reading
DensityGridExtraction
We’ve been working with Distance Grids which calculate how far a point is away from the closest surface point. They return a gradient that can be used in different calculations. A common use case is turning that gradient into some … Continue reading
Distance Transform
Distance function visualized through a gyroid volume. Solid red and blue are uncalculated inside/outside areas. Gradients are distance from the surface. Otherwise I thought it just made a cool animation. This forms the core of applying surface effects at a … Continue reading
ShapeJS
One of the main goals of the AbFab3D toolkit is to make it easier to create 3D printable objects. As a Java toolkit it’s only going to reach a limited audience(cue Venn diagram of Java programmers with graphics programmers). The … Continue reading
Voxel Sculpting
We’ve continued to hone the volume sculpting code. We recently added the ability to have GyroidGradients. These gradients allow you to modify the gyroid properties along the object space. A real world of example of this would be in reducing … Continue reading
