How to size and place text in Blender using Python

This example shows how to size and place text arbitrarily in the Blender environment. The Blender API offers a function to size text, however, it is limited to a minimum range of '0.1'. For some applications this limitation is undesirable. This example includes a function, 'textInBox', which generates the text so that it fits in a box of given height and width. So the box can be arbitrarily sized, the function converts the text into a mesh, find the size of the mesh, then scales the text to fix in the box. One key aspect of this example which is...

Quick-N-Dirty: A graph with labels in Blender

This example shows how to generate a 2-D graph in Blender with a 3-D appearance. This example illustrates how to generate a graph from data,size and position text anywhere and of any size,delete (unlink) all elements from a scene including the default cube, lamp, and camera, andcombine multiple meshes into a single mesh.

The repetitive and complex tasks in the example are implemented using functions. To build a line segment in the graph curve in the graph, the function 'lineSegMe' generate a mesh tube that runs from one point to another. To generate a complex curve, these tubes are strung together using...

Quick & Dirty: Example of generating a graph in Blender

This is a quick posting. It demonstrates how to generate an x-y graph in Blender. Two functions are introduced so a curve can be generated from mesh primitives. The join method is used to combine the mesh primitives into a single object which is easy to edit and modify.

SimplePlottingExample.py

Example demonstrating the following techniques in Blender 2.48 to 
generate a plot of x-y data:
1) Joining meshes
2) Use of the transform matrix
3) Use of material properties to control how objects are rendered
4) Delete (unlink) of objects in a scene
5) Use of cross products to generate a basis for...

How to set the render path in Blender

To set the location where renderings are saved in Blender do the following steps:

First, either press F10 or use the menus to select Render>Render Settings

Once you've done this, the panel at the bottom of the screen should show a collection of panels where the render settings can be changed. Select the text box which specifies where to save the rendered images.

How to easily copy code snippets from the formatted code display

When the code snippets are formated like this:

# code example
print 'Hello World!"

How to execute a script from the command line in Blender

With Blender you can execute a Python script when Blender is launched by specifying the scipt:

>blender -P myscript.py

Blender tranform matrix and building scenes from primitive meshes

In this tutorial, we'll work through several concepts in Blender. The three key concepts covered are: the use of the transform matrix (mesh.transform()) to orient and place a mesh in a scene, the use of material properties to control how a mesh is rendered, and the use of Blender Vector and Matrix classes. This example was built to begin working towards the generation of graphs in Blender. One of the first steps in generating graphs is the ability to draw a line from one point to another. This can be done in many ways. Two ways to do this are the direct generation of...

Using Python and Blender Game Engine to build an interactive visualization

The purpose of this example is to demonstrate how to use Python and the Blender Game Engine (BGE) to create an interactive visualization. When done, the blender model will allow you to rotate and move a polyhedron (pyramid) using the arrow keys when the game engine is running. I'm assuming you have anough knowledge that I do not need to walk you through every step in the Blender environment. As far as I can tell, Blender 2.48 does not support programmatic definition of BGE sensors, controllers, and actuators. Therefore, to use Python to define an interactive visualization in Blender, we need...

How to generate an animation using Python in Blender

This script takes the default scene in Blender, removes the camera, lamp, and cube, then adds in a new camera, lamp, and polytope. On each frame in the animation, the polytope is rotated. The script generates an AVI file of the animation. Additionally, this script shows one way to unlink or delete an object from a scene. It also shows how to use python to add a script to a text object, then link that script to an event in Blender. Note: I could not get this script to work when creating a scene from scratch. There appears to be an flag...

How to create a Polyhedron in Blender using Python

In this example, a simple 4 sided polygon is generated using meshes. The bulk of the example is dedicated to setting up the cameras, lighting, and rendering the image. The mesh is generated and linked to the scene in the following lines: coords = [ [-1,-1,-1],[-1,-1,1],[-1,1,-1],[-1,1,1], [ 1,-1,-1],[ 1,-1,1],[ 1,1,-1],[ 1,1,1]] faces = [ [0,1,3],[0,1,5],[0,3,5],[1,3,5] ] me = bpy.data.meshes.new('myMesh') me.verts.extend(coords) me.faces.extend(faces) ob = scene.objects.new(me,'myObj') ob.setEuler(0.2,0.2,0.1) The material for the mesh is created in the following code: mat = Material.New('newMat') # create a new Material called 'newMat' mat.rgbCol = [0.8, 0.2, 0.2] # change its color Once the material is created, it is linked to the mesh (not the object linking...
