Blend2Java.py Shows Errors While Trying To Export
That is one of the syntax changes between python2 and python3. python 2.x you would use print "some text" in python 3.x you use print("some text") What this means is the script is written for blender versions older than 2.50. Since 2.50 blender has used python3. The last update for...
Blender - Move mesh so that smallest Z point is on the Z = 0 plane
python,translation,scale,blender,mesh
The first thing you should know is that the vertex positions are in object space - as in distance from the objects origin. You need to use the objects matrix_world to translate that into world space. If you only want the lowest z location to be equal to zero then...
Unable to import a blender scene into three.js

ThreeJs and Blender (using colladaLoader): first contact
So, the first step is to learn how to create a scene in threeJs and learn some feature with Blender. When you are ready, create your first model and before exporting keep this in mind: you need to an object with vertices, so if you just create a text with...

Formulating the “close enough to zero” condition
Like Ami wrote in the comments, it depends on what you're doing. The system epsilon is good for single operation errors, but when you use already rounded values in further calculations, the errors can get much larger than the system epsilon. Take this extreme example: import sys print('%.20f\n' % sys.float_info.epsilon)...

Why is my three.js model missing faces after import?
three.js,blender,normals,uv-mapping
It seems that OBJMTLLoader can handle only triangles and quadrangles, but obj files can describe faces with any number of vertices, but the faces should be convex. If you check your model with http://3dviewer.net, you can see that every face exists, but there are some issues with non-convex faces. So...
How can I change the texture in a Blender model loaded into three.js, after it's been loaded, with ImageUtils.loadTexture?
The code wasn't working because there were no texture maps for the model I was importing. What I did was go back to Blender and create a model with two textures that could each be applied to the whole model. The exported JSON file then had the model geometry and...

Exporting morph targets from Blender to Three.js
Just to close this topic: After some trial and error, we ended up using one keyframe in Blender for each morph target (shape key) we wanted to export. The influence of the morph target was 1 (maximum) on that frame. So for 3 morph targets we had 4 frames (3...

Imported blender model has no color in three.js scene
You were using using 'mat' when you called material.

Can I set the ambient property of a MeshPhongMaterial to false in a three.js imported Blender model?
three.js,blender,phong,ambient
In practice, the ambient reflectance of the material should usually match the material color, also known as the diffuse reflectance. Doing so will likely make your model look better.

How can I get a sorted array of selected verts in blender python

Why does the number of vt and v elements in a blender .obj file differ?

Bytes-only operations like self._send(c1.raw) needs to be encoded correctly.

Workflow between blender and xcode (scenekit)
SceneKit supports materials exported in DAE from Blender.

Three.JS Blender Is Only Exporting A Single Object

fixing sharp looking geometry objects with widthSegmentCount property
This has nothing to do with the quality of your mesh. You are just seeing individual pixels without smoothing. SCNView exposes the antialiasingMode property that will help you get smoother edges (try .Multisampling2X or .Multisampling4X).
SCNNode static body with .dae causing issues

Difference between using OpenGL and 3D modelling software

The reason for the problems are rounding-errors with floating-points. Unfortunately, for floating-points addition and multiplication introduce small errors that can lead to problems with comparisons.
