Installing PyOpenGL-3.0.1 in Ubuntu 10.04 LTS

Why couldn't I find this in the first 6 hours of searching???

http://docs.python.org/release/3.0.1/download.html

And right there at the "Cheese Shop" too... aye aye yae! The instructions for installing were on page 8 of the 50 page document.

(*note: if you are seeing this for the first time be sure and install the necessary dependencies [see below], AND remove any former installations of PyOpenGL, such as PyOpenGL-3.0.0 before continuing)

All I had to do was download the tarball from http://www.python.org/ftp/python/3.0.1/Python-3.0.1.tar.bz2

Move it to /usr/local/src

Right click on it and choose "extract here".

Open a terminal and type:

cd /usr/local/src/PyOpenGL-3.0.1

Then:

sudo python setup.py install

Entered my password and watched it go.

Just like that I was back in business and running the afore mentioned demo on my other machine.

I should throw in a caveat here. I did in fact first install Numpy, PIL, and GLUT as dependencies already, for when I was running PyOpenGL-3.0.0. These all have executable "instant" installers available so long as you are running python 2.6. Find them here.
To remove former installation PyOpenGL-3.0.0 I just opened Synaptic Package Manager (System/Administration/Synaptic Package Manager) searched for "pyopengl", right clicked on "...3.0.0" when it showed up, and selected "Remove Completely".

A Simple PyOpenGL-3.0.1 Shader Demo

Alright. Here is that code that I mentioned in an earlier post. Know that you will need to install Python 2.6 and PyOpenGL-3.0.1 in order to run this code. It takes advantage of the new shader convenience module found in 3.0.1. This helped make switching shaders on the fly much easier to implement. Type "," or "." to page through shaders. "n" to toggle normals from "averaged" to "flat". When viewing "no shader" hit "1" or "2" to toggle light0 and light1 on/off respectively. Oh, and can't forget, "r" to start the spheres rotating. The sphere on the left is a glutSolidSphere, the one on the right is a sphere built from a .msh file that Mike wrote.

Look through the code! I hope it's helpful to someone, somewhere.

rendersphere.py
sphere1218.msh

PS. I may update this later and include more information on the dependencies and/or installing the correct versions of PyOpenGL... etc.

PyOpenGL-3.0.1 is only available as a tarball and/or .bz2 package. So... check
out my later post http://ultraopengl.blogspot.com/2011/07/installing-pyopengl-301.html for info on installing it.

Shaders I'm looking at...

Some OpenGL and Shader code I've found laying around the inter-webs:

Refract/reflect combined with facing ratio, and blinn specular

http://code.google.com/p/glslang-library/source/browse/trunk/trunk/glslang/shaders/material/reflect.frag.glsl?r=8
http://code.google.com/p/glslang-library/source/browse/trunk/trunk/glslang/shaders/material/reflect.vert.glsl?r=8
(should have named those last two reflect frag and reflect vert respectively)

especially look at the answer to this question and the links the answerer posted.

NETFLIX ON OPTIMUS V!!! (link I found)

My cell wasn't charging on any charger I could find. I was about to panic. I was searching for sites concerning the issue while I reset the phone and I found THIS!!! My phone is fine now that I turned it off and took the battery out, btw. smiles...

My thanks to Rock That LG Optimus V for the info.

Reminder to myself

Post the code that we worked up for the simple shader comparison tool in PyOpenGL. Why not share the knowledge with other beginners?! Good stuff. When we get deeper in I may not want to share all of our tricks, or I might not care... not sure, but, on this level, I KNOW I am hungry searching for good code and it is so hard to find, so, in good conscience, I just gotta do it. Unfortunately, I don't have it on hand. Thus, the reminder post. I'll erase this later. Peace. (as if anyone is reading this lol)

PS. What I am referring to above is that I got a few simple shaders working on Mike and I's sphere demo thing. Phong, multiple light phong, toon, point light. Basic stuff. Also we added the ability to swap out shaders on the fly to see the difference. Mike created triangle mesh sphere from scratch complete with proper VBO's to house the vertices and normals. He also created a version that has what he's calling "averaged normals". It makes a polyhedron (in this case shaped much like a sphere) appear smoother and rounder as if made from exponentially more triangles. Awesome technique. So know we have this demo thing where we can test new shaders and play around with GLSL and OpenGL. Next, come more complicated shaders, then textures, then effects... etc...

Installing PyOpenGL in Windows XP

I'm going to post this as is. I kept a record on notepad as I went. It ain't exactly a tutorial. Just a weB LOG of figuring out what to do!

Used this site as a reference point, (among others):
http://pyopengl.sourceforge.net/documentation/installation.html

It's sourceforge, so I tend to trust it, but I think it's wicked old...
BTW I am on my sister's family PC... ;) (stuck here dog-sitting)

Here's the rest:

Started just after 2:30am or so...

Installed (In Order):
python-2.7.2
PyOpenGL-3.0.1.win32

*could NOT install PyOpenGL-accelerate-3.0.1.win32-py2.6
because it requires Python 2.6 precisely.

- tried to install numpy-1.6.1rc2-win32-superpack-python2.6 (Numeric Python), but it
too requires 2.6.
-Downloaded the tarball file for Python 2.6.7 (Python-2.6.7.tar.bz2)j
-Downloaded and installed 7Zip.
-extracted the bz2 and then unzipped to the program files folder
- ^that did not work... apparently I need to use makefiles etc... and I'm not about to get into that whole process blind. Couldn't find any tutorials/instructions or forum chatter so...
-Downloaded MSI installer for Python 2.6
-^installed
-installed Numpy (see above)
-downloaded and installed PIL-1.1.7.win32-py2.6

(http://www.pythonware.com/products/pil/index.htm#pil117)
-Tried to install GLUT, but then realized that it SHOULD be included with the PyOpenGL
install (according to: http://pyopengl.sourceforge.net/documentation/installation.html)
-Downloaded PyGame installer for 2.6 (pygame-1.9.1.win32-py2.6) and installed.
-Installed PyOpenGL-3.0.1.win32
-Installed PyOpenGL-accelerate-3.0.1.win32-py2.6
-Installed Numpy

#will ANY OF THIS S#!T WORK? God knows...

It DID NOT appear to work (when I tried to run some Rubik's Cube/NEHE based code I found I got lots of discouraging errors, especially involving OpenGL calls and Numpy)

GACK!!!

Uninstalled everything I could find and re-installing... hopefully in the proper order this time...? (At least I already have all the installers found and dl'd)
4:31am

-Downloaded updated drivers for this crappy Intel video chipset on AK's PC and installed'em
-Restarting PC now
-Re-installed Python 2.6
-Downloaded and installed OpenGL Extensions Viewer 3.37
-It says that OpenGL 1.4 is the version on this PC
-Installed numpy-1.6.1rc2-win32-superpack-python2.6
-Installed PIL-1.1.7.win32-py2.6
-Installed PyOpenGL-3.0.1.win32 (which supposedly contains GLUT and GLE)
-When attempting to install PyOpenGL-accelerate-3.0.1.win32-py2.6 I got a pop up error
window. FAILED TO INSTALL ^^^^
-Spent an hour or so bouncing around the net like a fly caught in a spider web... googling
"pyopengl nehe" over and over in different forms

-FINALLY found http://pypi.python.org/pypi/PyOpenGL-Demo
-This package contains most of the NEHE lessons ported to PyOpenGL
-Ran Lesson 5 and it worked!!! yay!!!

TOMORROW I work on getting the tune shader working AND THEN phong...
5:45am Ouch...

Root LG Optimus V (Android 2.2 Froyo)

Well it appears I have FINALLY rooted my Optimus V! Woo Hoo! For those who don't know what I'm talking about, I have taken over the Android OS so that I can do all sorts of things like install custom apps and roms and, perhaps most importantly MOVE APPS TO THE SD DRIVE that won't move with App2SD alone.

Considering the tiny amount of available memory on this model, this is huge! In my humble opinion, this phone was starting to become a huge disappointment, because I was constantly having to remove applications that I really wanted, just so the phone would work. I LOVE my Android phone, but, in the end, it is a hand sized mobile computer and no computer with choked memory space is worth a crap in a fast paced world, full of brand new apps and things to try every week.

So here is the sight I primarily used to do the job.
http://forum.androidcentral.com/optimus-v-rooting-roms-hacks/57485-how-root-lg-optimus-v.html

Earlier in the evening (week, month... lol), I accessed all sorts of sites all over the net. I first tried the process in Ubuntu 10.04, couldn't seem to get it done. I won't get into why. I'm no guru and I didn't keep notes. If I had, they would only confuse anyone who read them. Myself included I'll bet. Anyway, here are some sites I did read to help figure out what I was doing and what I might be doing wrong. I'm still not sure why it didn't work the 2 or 3 times before the last try, because I don't recall changing anything really at that point.

I THOUGHT about using this method:
http://www.addictivetips.com/mobile/how-to-root-lg-optimus-v-virgin-mobile/

... but it involved putting files on the SD Card and it sounded more complicated than I wanted to get into at first. Later, however I may want to go back and install LEGO-ROM-V2. We'll see.

As per Revolution Red's instructions, I installed "Superuser" and "Titanium Backup".

Here is a sight with a "user manual" for Titanium Backup.

And a post I found at DROIDLIFE talking about moving apps. It mentions Titanium Backup, too.

Some notes on preparing Eclipse for Python Development

According to this site - http://clebeaupin.wordpress.com/2007/09/23/how-to-python-on-eclipse-ide/ - I'll be needing the following:

• WTP (Web tools platform) to edit CSS, JS, HTML and XML files
• CVS to work with CVS repositories
• Subclipse to work with SVN repositories
• Pydev to edit python files
• AnyEditTools to add very useful features in text edition

(I'm going with Subversive instead of Subclipse.)

Parts of the instructions on the page above are outdated, so I had to adjust for the Galileo distro that I am currently running. I referred to this site - http://download.eclipse.org/webtools/updates/ - to find out how to add the WTP to Eclipse.

Install WTP:
1. Open Eclipse. Go to Help>Install New Software...
2. Click on Add... (upper right)
The Add Site dialogue box appears.
3. Enter a name for reference (I used Web Tools Updates)
and enter http://download.eclipse.org/webtools/updates/ in the Location field.
You'll be back on the Available Software screen.
4. Click on the drop down menu arrow just to the left of the Add... button.
5. Find the site you just added and click on it.
6. Type "web" in the field that has grey letters reading "type filter text".

7. Check the boxes for:
Web Tools Platform(WTP) 3.1.2
Web Tools Platform SDK (WTP SDK) 3.1.2

8. Click the Next> button at the bottom.

9. Click I accept the terms of the license agreement
(It's open source, no worries!)

10. and click Finish.

Eclipse will go about preparing your packages.
About a minute later Eclipse will stop and ask you to confirm that you trust the Eclipse site from which you are downloading.
11. Check the box at the upper left and then OK down at the bottom to continue the installation.
12. When it finishes, you will want to click the button to restart Eclipse and your done.

Install CVS:
(TO BE CONTINUED>>> BED TIME!)

Install Subversive:

New Game Project

My brother, Mike, and I have begun working on a game. Get this - since he knows Fortran, because he's an aerospace engineer, we are creating in PyOpenGL, but also using a Fortran wrapper for some speedy mathematical calculations. It promises to be interesting.

So, off I go learning again. Here are some links I'm using to help with the PyOpenGL coding:

http://www.geometrian.com/Tutorials.php

http://pyopengl.sourceforge.net/context/tutorials/shader_1.xhtml

Sure wish I could find the original full source code to that one (above)!

As always, this is mostly for my own reference, but if I come across any useful information I will pass it along to the blog.
