How to manipulate individual bones of a 3d model in react native?

由 家住魔仙堡 提交于 2020-08-17 07:57:11
问题 I would like to display a 3d model of a skeleton (human body), using React Native. Then if I would like to set the position of specific bones of the human body, I would like to call a function like: setPosition(3dmodelObject,boneId,yaw,pitch roll); or setPosition(3dmodelObject,boneId,w,x,y,z); // If using quaternion example: setPosition(myHumanSkeleton,foreArmId,30,45,70); setPosition(myDogSkeleton,tailId,12,40,40); Can someone point me in the right direction so I can get started ? I've

Fitting polynomial surface to a 3D dataframe representing family of curves

由 大兔子大兔子 提交于 2020-06-29 03:32:14
问题 I have a 3-D dataframe representing family of curves: yi=f(xi) which are also depending on a third variable lets say zi (yi=g(xi,zi)) as shown in the graphic below: Family Of Curves The yi data are measurements and each curve is valid on its own. Now I would like to find out a proper way to fit a plane or surface to this data in order to avoid 2-D bilinear data interpolation. In general I am trying to do a similar approach as in the link below: 2D polynomial in Python With the difference that

How to import 3D models dynamically in a WPF Application

由 霸气de小男生 提交于 2020-01-12 19:27:16
问题 I have been searching this for quite sometime but could not find an appropriate method. How to import 3D models in a WPF application at runtime when user selects a model. It can be built in any one of the popular 3D modelling software, 3DS max, Maya, Blender etc, not all. Any one of the formats .3DS, .MAX, .FBX, .obj etc is required to be imported. If there are free libraries available for this, please mention them, and if i have to write the code myself, please guide how and where to start.

How can a 3D box with unequal sides fill the viewport, no matter its orientation in perspective?

问题 As shown in the included (three.js) live snippet (also at jsfiddle.net/gpolyn/une6tst5/21) *, I have a box with unequal sides that a viewer may re-position by dragging. The extreme left, right, top or bottom box corners in the viewport are dynamically indicated by green square dots. My modeling challenge is as follows: For a given viewport, present my box so that through all positions the dots with the longest window distance between them are at their respective viewport edges . So, for one

A-Frame .obj model displaying but broken

由 痞子三分冷 提交于 2019-12-31 05:36:16
问题 Total beginner to a-frame here, have been through the tutorial scenes and am now setting up my first using .obj models. Using a remote server, feel like that's important information. I've seen questions about models not showing up but mine is displaying broken and I'm not sure where to start fixing it. This is how it looks in windows 3D builder: And this is how it looks in my project (backed on pink plane for contrast): Here's the html: <!DOCTYPE html> <html> <head> <meta charset="utf-8">
