• Internet access is *slow* today.
• Tried to get ahold of Clif today to see what I should be doing. No luck yet.
• Deployed the lwjgl war to our servers. All seems to be working well.
• Working on shaders.
• Found another shader editor: http://www.opengl.org/sdk/tools/ShaderDesigner/
• And here’s the manual: http://www.opengl.org/sdk/tools/ShaderDesigner/ShaderDesignerManual.pdf
• However, the above does not run on my machine. RenderMonkey does though.
• Tutorials continued: http://www.lighthouse3d.com/tutorials/glsl-tutorial/. Got through to Data Types and Variables. The only odd thing that’s come up sop far us that FloatBuffer has to be set at twice its size to work in glLight(), otherwise I get the error:
• Number of remaining buffer elements is ‘X’, must be at least 4. Because at most 4 elements can be returned, a buffer with at least 4 elements is required, regardless of actual returned element count

• My timesheet’s not working. Sent Sally a note with a screenshot. Turns out the system is shut down for the week.
• Going to document all the moving pieces of the system – done
• Shader example for LWJGL: http://lwjgl.org/wiki/index.php?title=GLSL_Shaders_with_LWJGL
• I think the shaders are going to have to be stored as assets in the jar file? Or maybe deployed in the war?
• Got the shader code working. That was easy. Not messing with making it an applet yet – I’m going to work on making some more sophisticated shaders. Starting here: http://www.lighthouse3d.com/tutorials/glsl-tutorial/
• A physics library. How cool: http://jbullet.advel.cz/
• And a 3D engine: http://www.jpct.net/index.php That also works in applets.
• Installed RenderMonkey 1.82 for shader work.
• Charge 32.5 hours to leave on this timesheet!
• Trying to check in the sandbox project, but SVN isn’t asking for my password and as such, failing. Grrrr. Fixed.
• The correct SVN client for Indigo (Eclipse 3.7) is the one that is can be reached at “Indigo – http://download.eclipse.org/releases/indigo” in the “Install New Software” dialog. Select the “Collaberation” component and get the SVN pieces. I installed the following:
• Subversive SVN JDT Ignore Extensions (Optional)(Incubation)
• Subversive SVN Team Provider (Incubation)
• And that seems to work. I now have two SVN view categories that I have to choose between but I’m afraid to uninstall.

• Working on Applet stuff
• More pages that cover Javascript/HTML/Java communication: http://www.raditha.com/java/javascript.php
• It turns out that browsers call applets in unique ways, something that surprises none of you reading this. There  is a Java tool, called htmlconverter.jar that comes with the 1.5 (and greater?) jdk. More info is here: http://docs.oracle.com/javase/1.5.0/docs/guide/plugin/developer_guide/html_converter_more.html
• Going to try to run two applets inside the same web page and make sure that the canvas is allocated correctly.
• Looks like communication from JS to Java is handled through AppletLoader.getApplet(). Java to JavaScript is handled normally. http://lwjgl.org/forum/index.php?topic=3266.0
• More on communication, from the LWJGL website: http://www.lwjgl.org/wiki/index.php?title=Deploying_with_the_LWJGL_Applet_Loader_4_-_Polish_and_Tweaks
• Added my JavaScript color button. Events are working and I think it’s vanilla that it will work on all browsers? Yup. So far…
• Running the two applet webpage on fgmdev here: http://fgmdev.com:8080/lwjgl/twoApplets.html. It took one refresh to get everything working in Firefox, but Chrome and IE worked just fine. If you try this in your browser, let me know how it works in the comments section. Focus works too. If you click in the applet, you can move the rotating square with the arrow keys.
• Sending a string from JavaScript to the spinning quad via the LWJGL Appletloader:
• document.getElementById(‘myApplet’).getApplet().setColor(colorStr)
• Working on communicating with JavaScript from the applet.
• Doing this with Maven: http://rostislav-matl.blogspot.com/2011/10/java-applets-building-with-maven.html
• Had to point the buildpath at plugin.jar, which was in my Java jre/lib directory. It’s not in Maven. If this all works, I’ll add it to our local repo.
• Got it. You can call a JS function or an element in the document. Kinda cool, actually. This turned out to be the most useful link: http://www.codeproject.com/KB/scripting/javatojs.aspx. You can play with the running code here.
• Cool pix for the day – multiple applets running in all browsers:
• 

• 8:30 – 4:30 VISIBILITY
  • Going through the LWJGL tutorials here.
  • Got a window test up and running with keyboard interaction and (fast!) animation.
  • Added Applet capability to the above. It runs in the Eclipse Applet viewer. Now I need to get it to run in Tomcat…
  • Sun/Oracles Applet development examples
  • Deploying with the LWJGL Applet Loader 1 – Basics
  • Success! Using basicapplet.html in Phil/applet/lwjgl folder. Need to look at how to send data between the wrapper and the 3D app, since it’s going through the lwjgl applet wrapper.
