## Wings 3D Has a GUI Problem on my builds of Linux.

In keeping with my recent theme, of testing various 3D editing applications available under Linux, I next tried out “Wings3D”, which is available in the Debian repositories / package manager.

And one detail which I found frustrating, was that some of the dialog boxes – if not all of them – have problems displaying correctly on the current build of Linux.

I get the impression that Wings3D is actually quite powerful. But unless the Right-Mouse-Button (‘RMB’) clicks reveal their full Context Menus, it can be hard to get started with this application.

There was just a specific exercise which I undertook this evening, which was to try assigning a custom material – and therefore an arbitrary texture image – to an arbitrary 3D model, even in a situation where the texture image made no sense, just to get a feel for how it’s done. While getting started with this, I learned that objects must be U,V-mapped first – which is actually nothing new. And, advanced 3D editors such as Wings3D, do have a semi-automatic U,V-mapping option. The trick is for a person who has never used Wings3D before – actually to find it!

We can select a model to work on, and then we’re supposed to RMB, and from the context-menu, pick the ‘UV-Editor’. The problem with my build of Linux is, that the last entry of the context-menu is actually this option, and it doesn’t display correctly! Instead, in its place, all we get to see is a dot. When I’m looking for a UV-Editor option in a context-menu, to UV-Edit a specific model, I don’t usually think, that the entry which is actually displaying As A Dot – Is It.

Once I discovered this detail, I was able to make progress by trial-and-error.

There is a way for users in general to make out the entries in the Wings3D context menus, that are not being displayed correctly, and that is to hover over those entries, and to observe what the bottom, green bar tells us. It will update, and display information about how to use the menu-entry being hovered over – including what that entry is called !

I solved this problem, by upgrading to the latest version of the application.

For Debian / Jessie, the package manager only offers version 1.5.3 . But we can actually install version 2.1.5 quite well, from the Web-site.

## Widening Our 3D Graphics Capabilities under FOSS

Just so that I can say that my 3D Graphics / Model Editing capabilities are not strictly limited to “Blender”, I have just installed the following Model Editors on the Linux computer I name ‘Klystron’, that are not available through my package-manager:

I felt that it might help others for me to note the URLs above, since correct and useful URLs can be hard to find.

In addition, I installed the following Ray-Tracing Software-Rendering Engines, which do not come with their own Model Editors:

Finally, the following was always available through my package manager:

• Blender
• K-3D
• MeshLab
• Wings3D

• PovRay

In order to get ‘Ayam’ to run properly – i.e., be able to load its plugins and therefore load ‘Aqsis’ shaders, I needed to create a number of symlinks like so:

## Completed Installation of Crystal Space on Klystron Today

In This Posting, I wrote that I had installed “Crystal Space 2.1” on my laptop named ‘Klystron’.

This is an open-source game engine, which competes with “OGRE“, the latter of which is also open-source.

It is not enough just to have the game / rendering engine installed. In order to create content, authors also need to use 3D Model Editors, and the most important of those available in the open source community, happens to be ‘Blender‘, which has its own file-formats for storing projects.

Therefore, one also needs to install the add-on into Blender, which will allow it to export what we have created within it, into Crystal Space format. Fortunately, when I compiled Crystal Space, I did so with full Python support. Blender scripts happen to be written in Python. And in the appropriate shared directory, the Blender add-on could be found.

One word of caution though. In order for this add-on to work properly, Blender must be started with the ‘CRYSTAL‘ environment variable set. This can be done from the command-line, but eventually the authors will want that taken care of automatically.
