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.

HTML5 WebGL/Canvas – Standard Slide – sneak peek

Year ago we developed application for navigating in Standard Slide catalog. It was written in Flex and still it’s serving very well.

This year we decided to make further step and we’re preparing version in HTML5. Not only that. We would like to show 3D models right in the browser.

Many thanks to Three.js for great Canvas/WebGL library.

I’ll share small sneak peek with you. I recommend to view it in Google Chrome or Firefox 4+ which has support for WebGL. Other modern browsers supports Canvas and 3D model will be displayed there as well.

Application is not finished yet. Models are in prototype version. We have to fix some issues, but it nicely demonstrates power of HTML5.

Update: You can test newer version 0.6

Test Standard Slide 3D version 0.6.

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:┬áC:\Program Files\Blender Foundation\Blender\2.58\scripts\modules

Blender 2.57 – how to change font size of UI

Blender has 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.

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 bigger font. ­čÖé

Note: There is also useful Blender training at lynda.com.
