Hello everyone, For my project’s needs, I built a function that changes attributes.position values to taper the cylinders ends. Currently it works perfectly only if heightSegments = 1, but I could probably fix that too. I think that it would be useful for many users to have the above extra featur…

In the last years the geometry generators were not further enhanced since they already have a certain complexity which is not easy to maintain. Hence, I doubt that this feature will be accepted in the main repository. However, feel free to share your implementation in the Resource category of this …

ProfiledContourGeometry MultiMaterial Resources

With reference to ProfiledContourGeometry and Simple Rectangular Geometry Extrusion (Anyone?) here another variant of the creation of such a geometry. An indexed BufferGeometry will be created. Look there: http://threejs.hofk.de/ProfiledContourGeometryMM/ProfiledContourGeometryMM.html The definition is done without using any other three.js objects except THREE.BufferGeometry( ). This makes it very easy to use MultiMaterial. There are two different modes to choose from. In 7 colo…

ProfiledContourGeometry Resources

Evolving of that post [ProfiledContourGeometry3] The function has four parameters: THREE.Shape() for a profile; array of THREE.Vector2() for a contour; a boolean value for closing the contour (default is true); a boolean value for open ends (default is false). It calculates an angle between two edges of contour and then consiquently applies three matrices of shear/shift, rotation and translation to the points of the profile at each point of contour. The solution is still rough and raw, an…

Simple Rectangular Geometry Extrusion (Anyone?) Questions

I am struggling to do something which should be quite easy to do, but I have been unable to find any example which addresses this scenario. Essentially all I want to do is extrude profiles along a rectangular path: This is the profile: [image] This is what I expect the end result to be: [image] What I actually get is this: [image] I would appreciate it if someone could look at the code below and tell me what I am doing wrong: '-----------------------------------------------------------…

Addon to create special / extended geometries Resources

Another geometry. Sphere with up to 6 coordinate planes parallel holes. There are two different designs of the faces. The variants: completely symmetrical efficiently The geometry is realized as indexed BufferGeometry and supports MultiMaterial. geometry = new THREE.BufferGeometry(); g.createSphereCut = THREEg.createSphereCut; g.createSphereCut( p ); // mesh mesh = new THREE.Mesh( geometry, materials ); // multimaterial array with 8 materials scene.add( mesh ); From …

Triangulation cylinder with holes Resources

The triangulation of the cylinder with holes is similar to that of the sphere. Triangulation sphere with holes But with different parameters. For the sphere this variant is also in progress. Try it out https://hofk.de/main/threejs/Triangulation/TriangulationCylinderWithHoles.html (UPDATE February 2020: Combination of shapes, see Inner Geometry (Triangulation) ) One variant is integrated in the addon THREEi. Addon for triangulation of implicit surfaces/ forms with holes Cylinder with …
