Cesium czml change orientation of 3d model (gltf/glb) along with position in time

由 空扰寡人 提交于 2019-12-23 13:01:20
问题 I have implemented a 3d model (cesium air) aircraft to move along a path. Its position is being changed based on time and the detailed data is available in the czml file under position attribute. However, I am not able to change the orientation of the aircraft along with path. The aircraft flies through the path but its heading , pitch and roll are constant. It does not pitch up with increase in height etc. How to implement the attitude changes using orientation attribute in the czml file or

问题 I took the code from the A-Frame School in which a gltf model is loaded.

The sample code does work locally,

Why is blender rigged animation distorted when exported as GLTF?

由 穿精又带淫゛_ 提交于 2019-12-22 09:53:26
问题 I created an animation in Blender with armature rigging. When I test it in Blender by pressing Alt-A, it works perfectly fine. However, when I export it as a .glb using the KhronosGroup GLTF exporter, the resulting animation is distorted (e.g., limbs are disconnected and moving in a weird way). Why is this happening (and how can I fix it)? For the past two days, I have been trying solutions from similar questions (such as applying location/rotation/scale with Ctrl-A, or deleting the Armature

问题 QUESTION: After converting my FBX file to a .gltf, the model is incredibly small, why ?

How to export morph changed meshes from threejs application?

由 [亡魂溺海] 提交于 2019-12-11 19:56:02
问题 I'm trying to customize a mesh and then export it by using gltfExporter from Threejs, however it still exports with all morph/shape keys attached, I would like to remove them in the final export mesh. Cloning the scene / mesh didn't work. function exportModel() { var exporter = new THREE.GLTFExporter(); if (!gltfExportEnabled) gltfExporterConfig.binary = false; var finalRenderModel = mainScene.children[2]; // Remove Morph Targets if (!!removeExportMorphs) { // finalRenderModel.children[0]

Getting an {“isTrusted”:true} error when using GLTFLoader

问题 QUESTION: Everything was working fine: I converted my FBX files to GLTF inside my /GLTF/ subfolder. Sadly, some geometry was missing from some of the converted files, so I tried to convert again my FBX files, this time to /TEST/. Suddenly, the models don't load and from my console.log statement: console.log( 'An error happened: '+JSON.stringify(error) ); I get this strange useless error: An error happened: {"isTrusted":true} So I try to convert my FBX files to .glb instead, this time to

How to load a gltf model to Three.js?

由 落爺英雄遲暮 提交于 2019-12-08 18:48:36
问题 I decided to try out gltf format for rendering models in Three.js and I'm using this converter (http://cesiumjs.org/convertmodel.html) to convert the model from Collada to GlTF. It spits out a *.gltf file, however in the examples in Three.js they pass a *.json file. How can I load the *.gltf file or how can I get the proper set of files to load? Thanks 回答1: You can use THREE.glTFLoader which can be found in the examples/js/loaders directory. For a demo, see http://threejs.org/examples/webgl

Is there a way to convert gltf to dae?

由 我们两清 提交于 2019-12-07 05:40:54
问题 I can make gltf files with the collada to gltf converter. But is there a way to reverse this? 回答1: UPDATE - October 2019 - Blender 2.80 has shipped with full glTF 2.0 import/export capability. It also has COLLADA import/export capability, so can be used to convert one to the other. UPDATE - November 2018 rewrote answer for glTF version 2.0, which has almost completely replaced 1.0 in the time since this question was originally asked. glTF 2.0 can be processed by a variety of tools, many of
