Working with GLFW library under Fedora.

Today I will try to use GLFW library.

GLFW is a C library that lets you using an OpenGL context and window, display modes and inputs like keyboard, mouse, joystick and time.

GLFW supports Windows, Mac OS X and Unix, Linux and FreeBSD and any operating systems with the X Window System.

Also you can read more about this library here.

First install the library using root account.

Now let’s see the source code.

First I includes all librarys I need.

In the main function I start to see if the library is working.

The next step is to set some settings, see:

… and also testing the desktop settings.

The settings it’s show on console with cout function.

Now I make the window context using fullscreen option.

I set the title of the window.

I enable the keys.

The next source code it’s close the window.

Testing with time command to see how fast working.

The netbeans IDE make the package in this path.

I make RPM package for Fedora distro.

I test my example and working well.

Using bpy module to select and active some objects

Today I will show something about Blender 3D scripting.

The last version of Blender 3D use Python 3.

This told us : you need to know how to programming in python language.

After you start the Blender application go to Scripting Mode.

blender-bpy-001

The blender application will change the windows and make all for you.

blender-bpy-002

The Blender 3D application use bpy module to deal with all blender stuff.

The bpy module come with some python modules.

bpy.context

bpy.data

bpy.ops

bpy.types

bpy.utils

bpy.path

bpy.app

bpy.props

The Blender 3D come with autocomplete source code (Ctrl+Spacebar keys) and can be change from Blender 3D menu

File – User Preferences – Input

Let’s try some examples…

I created one python script for selection and make active object.

First rule about selection is: only one can ever be active at a time, but you could have many objects selected .

See the script: the next line will make active the Camera object.

This will show us the active object. In this case will show us : Camera.

bpy.data.objects[‘Camera’]

The next lines of python source code allow me to:

select all or deselect all objects in the scene:

deselect all objects

select all objects

You can select the object by type: ‘MESH’, ‘CURVE’, ‘SURFACE’, ‘META’, ‘FONT’, ‘ARMATURE’, ‘LATTICE’, ‘EMPTY’, ‘CAMERA’, ‘LAMP’, ‘SPEAKER’.

Also you can select some Blender 3D windows feature.

Let’s change the window mode from 3D windows.

You need to select the default cube or another editable object and use the next line of python source code.

I selected just two objects and will make one list.

Now I will print collect selected objects.

Using for and if we can use all selected objects:

You can try also on your Blender application.

I will come with more complex examples in the future.

Using Ivy Generator with Blender 3D version 2.64

I used this addon with blender 2.64 and working well.

I don’t think will be problems with the last version of blender : 2.66 .
