3D HTML inspection in Firefox

Firefox has one very neat feature for web developers – 3D inspection. It’s very useful when you need to examine layer overlay or event bubbling.

Just right click and choose Inspect Element:

firefox-inspect

You’ll switch to inspect mode. Click 3D View in the right bottom corner.

firefox-3d

Simple :)

Create mesh with correct faces in Blender by Python script

This video tutorial explains how to create mesh using Python script.

Vertices must be defined in right order when we want to define correct face.

Let’s imagine that we would like to create following object:

Numbers are marking vertices beginning from 0.

Let’s define them:

faces = ((0,1,2,3), (1,2,6,5), (1,0,4,5), (2,3,7,6), (0,3,7,4), (4,5,6,7)

Just display normals to see whether everything is ok.

As you can see, only few faces have correct normal.

In order to define face correctly use following rule:

Imagine that you’re sitting inside object and you’re looking outside.

You have to define face by naming vertices in clockwise fashion.

Solution is:

faces = ((0,1,2,3), (5,6,2,1), (4,5,1,0), (2,6,7,3), (0,3,7,4),(7,6,5,4))

Writing Python scripts for Blender with Intellij IDEA

Blender is powerful 3D modelling tool. What makes it really powerful is support for Python.

I was playing little bit with configuration of Intellij IDEA and I found out that it is possible to use Intellij IDEA for developing Python scripts for Blender.

Here is video tutorial:

Update 23.06.2011: Video tutorial was recorded for Blender 2.57. There is small change in Blende 2.58 – scripts are located in Program Files directory, like: C:\Program Files\Blender Foundation\Blender\2.58\scripts\modules

Blender 2.57 – how to change font size of UI

Blender has a very small font in UI elements. This is quite problematic when you’re using high resolution. It’s quite hard to read tiny letters.

I spent several minutes searching for the option how to change font size.

It’s quite easy, but not obvious.

Go to File menu, select User Preferences. Select the last tab System.

Change option DPI in section General.

Change resolution to desired DPI.

It’s the first option, but it took me several minutes to realize that changing this value will result into a bigger font. :-)
