Blender2.8安装Armory3D插件
下载blender2.8 https://www.blender.org/download/ 下载ArmorySDK https://armory3d.org/download.html 将Armory3DSDK解压到指定的某个目录 unzip -d /your_path/ armory.zip Blender添加Armory3D插件 打开blender2.8 打开addon配置：Edit -> Preferences -> Add-ons 点击Install, 在打开的文件选择框里跳转到Armory3D的解压目录， 选中 armory.py , 点击确定。之后在 Community 一项中可以找到新安装的amory: 配置SDK Path (设置为解压后的armory目录)： 设置armory的代码编辑器 (使用外部编辑器来写代码, 比如这里使用了vscode) 安装完成后，在blender的操作界面中，可以看到armory相关的功能项都已经显示出来了，比如： 来源： CSDN 作者： moxiaomomo 链接： https://blog.csdn.net/moxiaomomo/article/details/104125680
Blender 建模
1.多图层切换 Blender也有图层的概念，我们在一个图层上建立了一个模型，可以在另外一个图层新建一个独立的模型。界面底部包含了Layer切换按钮。如下图所示： 当前我们正在操作第一个图层，如果想在其他图层上新建模型，只需单击空面板即可。当然可也可以直接使用快捷键M自动弹出图层面板，选择切换。 2.导入图片 使用快捷键N打开属性面板，勾选“Add Image”选项，导入一张想要建模的图片。按快捷键“5”，把视口切换到正射投影，这样切换到每个面的时候看的效果就像平面一样。结果如下图所示： 上图右边有一个Axis选项，可以设置图片在哪个面显示，All View或者Front、Back等等。我们可以通过选择不同的面，为每个面设置一张模型，从各个面补充图片，体现3D效果的各个面。 3.增加边缘 如下图所示，我们需要环体的中间位置放大，和杯子边缘重叠。可以使用CTRL + R，在中间位置增加一条边缘，并且可左键单击该边缘向上下条件。同理，我们也可以在任何水平和垂直位置这样添加边缘。 4.平滑表面 如下图所示，下图是建模完成了建模，现在要修复顶部，把顶部磨平。先通过CTRL +Ｒ在下图框选部分添加一条边，并且使用Ｇ和Ｚ组合把边缘移到底部偏下一点点的位置。 拖动后效果如下。但现在顶部表面不是平滑的，如何平滑？选中最顶部的顶点环，按快捷键“I”，可看到从顶部环中心位置有一个平滑的圆环出现
Blender 界面操作
1.旋转场景 使用鼠标中间键旋转整个场景。按住Shift键，再操作鼠标中间键则可平移整个场景。 2.数字键盘功能 数字键盘1、3、7，分别控制场景向前、向后、向上显示。 数字键盘5，可以在正射投影（Ortho）/透视投影（Persp）之间切换。 数字键盘0，从摄像头位置处查看物体，这个位置查看的物体也只最终呈现出来的视角。 当我们想对半选中物体一半的部分选中，可以先按5，把视图切换到正射方向，然后再按3键从前向后查看。 如果使用笔记本,可通过打开File->User Preferences…，切换到input页签，勾选”Enulate Numpad”。点击“Save User Settings”。现在就可以使用笔记本的数字键模拟小键盘数字键功能了。 3.如何选中物体 Blender和其他软件不同，如果我们习惯性的用鼠标左键去选中物体是没有一点效果的。Blender默认是使用鼠标右键选中物体。但如果我们是在操作不习惯，可以打开File->User Preferences…， 切换到input页签，在“Select With”选项中选中“Left”，保存设置。现在可以用鼠标左键选中物体了。 选中物体后，怎样拖动物体？按住鼠标右键，拖动物体。 4.添加和删除物体 按SHIFT + A弹出新增菜单，可以选择想要添加的物体。也可以在工具左侧的面板的“Create”选项卡中添加物体。
Blender database using Python (errors)
问题 I'm using Blender 2.74 and Python 3.4 with the correct connector for MySQL. (By the way, I'm just a beginner in using Blender and Python.) What I want is to make a login UI and save the inputted name into the database, but my code seems a bit off or wrong. When I try to run the code, it didn't save the value in the variable, but when i try to run it in python IDE (PyCharm) it worked. Here's the code: import sys sys.path.append('C:\Python34\Lib\site-packages') sys.path.append('C:\Python34\DLLs
Create an Array of Meshes from Object (THREE.JS and GLTF)
问题 Below is my piece of code which loads a mesh onto the object. At the moment its traversing through the entire thing. Current code: var loader = new THREE.GLTFLoader(); loader.load( '../gtf/Box.gltf', function ( gltf ) { model = gltf.scene; gltf.scene.traverse( function ( child ) { if ( child.isMesh ) { child.material.map = texture; } } ); scene.add( model); } ); How would I go about making an array of children[] ? Each child will would then allow me to assign separate textures. I have made
play animation once instead of looping three.js
问题 I have exported blender JSON animation into THREE.js, everything works fine, but I want to play the animation only once and stop instead of looping the animation. 回答1: Old question, but in case anyone needs it the solution is to set animation.setLoop( THREE.LoopOnce ) let objLoader = new THREE.ObjectLoader() objLoader.load('./your.json', function( obj ) { scene.add( obj ) animationMixer = new THREE.AnimationMixer( obj ) animation = animationMixer.clipAction( obj.animations[ 0 ] ) animation
How do I integrate C++ library with Python?
问题 I want to integrate Berkelium (www.berkelium.org) with Blender to render browser in Blender scenes. Blender allows you to write python add-ons (http://wiki.blender.org/index.php/Doc:2.6/Manual/Extensions). I know only a little bit python what would be a good starting point for me? How do I call Berkelium methods in my python add-ons? Here is the link for Berkelium builds: https://github.com/sirikata/berkelium/downloads 回答1: It seems this is covered by the python docs. Perhaps this will be of
How do I tell frag-shader which texture (of many previously loaded textures) to use per vertex of an external generated 3D file?
问题 I'm trying to figure out the best way to load a textured 3D model into my webGL application but I'm having some trouble with it. My 3D models have more than 1 texture and I don't know how to tell the shader which texture to use per vertex as this info doesn't seem to be included into the 3D files I looked into so far. I'll give an example: I have modeled a wooden chair with a leather seat/cushion in Blender. Which format should I export the chair to make it easy and efficient to extract: -
How do you load Blender files using Assimp?
问题 I tried to load Blender file using Assimp library on C++ using the following code, but it fails since it doesn't have any meshes at all. The blender file I am using is the default cube saved using Blender itself. Assimp::Importer importer; const aiScene * scene = importer.ReadFile( path, aiProcessPreset_TargetRealtime_Fast ); if( !scene ) { fprintf( stderr, importer.GetErrorString() ); return false; } const aiMesh * mesh = scene->mMeshes[0]; // Fails here since mMeshes is NULL What am I doing
