PCI 3.0 - refresh of graphics.

The PCI-SIG finalized the specifications of PCI-Express 3.0 bus.
Is designed to be backwards-compatible with devices that use older versions of the bus.
The new PCI-Express 3.0 has, resulting in a data-rate of 1 GB/s per lane, per direction.
The first PCI-Express 3.0 compliant devices will come to be in 2011.
You can read the specifications from official source.

GLEW 1.5.7 Released

The new update of GLEW adds the GL_NVX_gpu_memory_info extension and fixes some compiler bugs.
You can download it from HERE.
GLEW named "OpenGL Extension Wrangler Library" is the most popular OpenGL extensions management lib.

Ogre 3D - First steps

I just tried to use 3d engine - Ogre 3D. Although I have not programmed in C + + for a very long time, the tutorials found on the net helped me a lot. Installing this engine linux distribution - Fedora is simple, it seemed more complicated in Windows XP. I used IDE Code:: Blocks and here's what resulted:

Blendern 3D - Shape Modeling Exercise #5 by Kernon Dillon

I saw this video tutorial by Kernon Dillon. Is a simple one , but just let us to know some modeling techniques. With a duration of 27 minutes, the tutorial must be seen by those who use this software.

OpenGL and Python - GLSL example

Today I played a bit with GLSL.
Here is the final result in the image below:

The source code used by me:

vertex shader
varying vec3 normal;
void main() {
  normal = gl_NormalMatrix * gl_Normal;
  gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;
 }
fragment shader
varying vec3 normal;
void main() {
 float scale = 1.0 / 10.0;
 float frx = fract(gl_FragCoord.x * scale);
 float fry = fract(gl_FragCoord.y * scale);
 gl_FragColor = vec4(frx,fry,0.0,1.0);
 }

PyOpenGL - first lines of code.

What is the best way to write the first line of code on pyopengl ?
Please see below :

Python 2.6.4 (r264:75706, Jun  4 2010, 18:20:16) 
[GCC 4.4.4 20100503 (Red Hat 4.4.4-2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from OpenGL import platform
>>> dir(platform)
['CurrentContextIsValid', 'GL', 'GLE', 'GLU', 'GLUT', 'GLUT_GUARD_CALLBACKS', 'GetCurrentContext',
 'OpenGL', 'PLATFORM', 'PlatformPlugin', '__builtins__', '__doc__', '__file__', '__name__', '__package__',
  '__path__', '_load', 'baseplatform', 'copyBaseFunction', 'createBaseFunction', 'createExtensionFunction',
   'ctypesloader', 'getGLUTFontPointer', 'glx', 'os', 'safeGetError', 'sys']
>>> gl=platform.OpenGL
>>> print gl

>>> glCreateShaderObjectARB = gl.glCreateShaderObjectARB
>>> glShaderSourceARB = gl.glShaderSourceARB

As we can see, is simple to start it.
Just use gl.function_opengl.
