WebGL - now in beta stage in Google Chrome

WebGL is now in beta stage in Chrome. WebGL is a 3D graphics API .
This JavaScript API can be use to create 3D web apps.
As we know it is based on the OpenGL ES 2.0 API
My verssion is 9.0.597.19 beta Google Chrome and run well the demo from here.
It moves a little hard but working on an Asus Eee.

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.

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.

Sunflow rendering on Fedora 13

How to install Sunflow ?
It's pretty simple just download the zip archive from here.
Unzip and edit the sh script sunflow.sh
from the sunflow folder.
By default the script is:

#/bin/sh

mem=1G

java -Xmx$mem -server -jar sunflow.jar $*

If we run this script will have this error :

$ sh sunflow.sh 

Invalid maximum heap size: -Xmx1G

Could not create the Java virtual machine.

The solution is:

$ whereis java
java: /usr/bin/java ...

Now change the script :

#!/bin/bash
/usr/bin/java -Xmx1024M -server -jar sunflow.jar $*

And run it ...

$ sh sunflow.sh 

The result is :
