BlendInspect is a free tool to visualize the blendmodes that are available in OpenGL.


BlendInspect is best downloaded via webstart.


All you need is Java and an OpenGL-compatible graphics card. Java can be freely downloaded from the website.

can you write the display function of this code. I just dont understand the blend thing. Maybe with your program and the src code of display func, my mind will be at ease.

That is strange. If I cancel the save then it runs.

Maybe when I try to save there is a permissions issue and it messes up the process? But if I cancel then it works.
macnib 05. October 2007
Still not working.

I just get the application menu. Also, it asks to save the application to a folder. It appears the app is never saved to the folder.

Also, I did not have Open Safe files check in Safari. So, I had to double click on the blendinspect.jnlp file on the desktop to get it going. If I did check the Open Safe files in Safari it worked automatically. But it just produced the same situation as described previously.

BlendInspect has just been updated in order to also work on Macs. Please let me know of any issues.
matthias 02. October 2007
thank you everybody for your feedback!

it seems as if there are currently two problems running this webstart app.

1. on linux and windows you need at least a java-version larger than 5.

2. doesnt work at all on macs. at the moment i have no idea why, but i'll look into this.!
macnib 02. October 2007
This does not work on the mac. 10.4.10.

java -version
java version "1.5.0_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-164)
Java HotSpot(TM) Client VM (build 1.5.0_07-87, mixed mode, sharing)

Looks like you signed the certs yourself. So, there are a few warning windows. No problem.

I get to the point where it asks me to create an application. But there is no application created.

Well, there was some sort of process running but it was just a menu. I could get a about window which just said Java.

Sort of bummed. Wanted to see all the blending because its useful.

The webstart WORK on my Macbook Pro, but I see only a black rectangle on the upper left corner and nothing...

Try to fix this... cuz it can be really usefull especially if you can directly load/run from the page.

Your concept is good, just need a bit of fine tuning ;)

(I still bookmark your page... hoping that you'll fix this...)

anonymous 02. October 2007
Doe'snt work on my pc also, same sort of exception message!
anonymous 02. October 2007
It does WORK on linux. I am using the latest jvm (java 1.6).
Alex 02. October 2007
hmm, it doesnt work on my PC (P4 3Ghz XP ATI 1600XT).

I see only a white Window with about 3 PixelLines (~80 Pixel long) in the upper left corner
