Here is in mind a better version of _CreateCube()

it returns the ID of the diffrent sides allowing you to add a texture to the diffrent sides of the cube.

and in the older version 2 of the sides was wrong way, you couldent see it unless you added texture to the each side of the cube

Edit: Small question, is it possible to change a texture while the window is runing??

Yes, you can change shape texture while running the window, just set the texture again in same shape.

I'll test your scripts in monday, cause I'm using today the computer fo my fiance.

... and if you want, can I put it in next version?

[A. Percy]

@Alek - Very usefull your function. I tried your example

Very good!

[A. Percy]

Update.

DefineGlWindow improved.

And CreateCubeEx by Alek added

Hi,

First I must thank you for creating such an awesome plug in.

However, I have problem running the examples that involves ntdll.dll which generates a crash message when ever an example with "Texture" is started. SciTe would start compiling it and fails to start with a windows error message. I have a dedicated card as shown below which show definitely support OpenGL, I am unsure why this is happening and search of the forum does not reveal the proper solution to my problem. Therefore, I have posted here for help. Thank you for any replies.

Here's some basic sepc:

Vista 32 bit Home Basic

8600m GT

C2D 1.6

I didn't test on Windows Vista, but mrbond007 told me about the same problem:

@A. Percy

Great example dude

after posting a file to the download page you need to wait for Jon's approval. If Jon accepts the file it will be available for the rest of us, but it's better not to include exe files, you can put all your uncompiled scripts, examples and the dll files in one zip file and than upload it to the download page.

the reason that T2 and the examples doesn't work on Vista is because the Texture functions returns error "1 - unable to use the dll file". maybe if you try calling the api straight from the gl files ??. Anyway temporary disabling the texture funtions in the ItCopter works sometimes .

Cheers

Baki

So, I need Windows Vista to work on some solutions for this problem. I need some time

Thank you for your help.

Some people asked for embeding the plugin window into a GUI from autoit. Today I found a nice example about embeding a window, by SmOke_N.

Is it possible to embed Windows Explorer?

Update released today.

May be frustrating for Windows Vista users, but I didn't fixed the Vista problem yet. My fault. :">

For other users, I added EmbedGlWindow funcionality. Now it's possible to add the gl window to your own form.

Thank you

[A. Percy]

Hi

If you have problems with texture mode, take a look here.

Thanks to danwilli

[JohnWang]

Yes, you can change shape texture while running the window, just set the texture again in same shape.

I'll test your scripts in monday, cause I'm using today the computer fo my fiance.

... and if you want, can I put it in next version?

Hi,

I have tried the above using, Texture Add, and Texture Bind, and the use of Capture Screen function to update the screen. It works and the screenshot refreshes and update the cube I was using. However, every time the function TextureAdd is called it use up a small amount of ram (probably because the cube was small. Also I have exclude the possibility that the Screenshot/Screenshot function was using the RAM by Isolating it), and with a while loop set to update the texture can result in gigs of RAM used up in matter of couple of minutes. So, is it possible to by pass this by removing the texture from the RAM once it is used presently? If not, do you plan to write a function in the near future for such function?

Thank you in advance, this plugin is awesome, and I really appreciate you spending your personal time maintaining it.

I have tried the above using, Texture Add, and Texture Bind, and the use of Capture Screen function to update the screen. It works and the screenshot refreshes and update the cube I was using. However, every time the function TextureAdd is called it use up a small amount of ram (probably because the cube was small. Also I have exclude the possibility that the Screenshot/Screenshot function was using the RAM by Isolating it), and with a while loop set to update the texture can result in gigs of RAM used up in matter of couple of minutes. So, is it possible to by pass this by removing the texture from the RAM once it is used presently? If not, do you plan to write a function in the near future for such function?

Thank you in advance, this plugin is awesome, and I really appreciate you spending your personal time maintaining it.

Thank you!

It's a good idea. I'll do something about it.

In next month I'll buy a new computer and finaly I'll can give more attention to my projects, including the plugin.

Thank you again!

You need glut32.dll and au3glplugin.dll on your machine.

Edit: and glaux.dll

What is the base unit for shapes, pixel? For example, I used AddCube and I want it to fit the screen perfectly, but a 240 in the width parameter will exceed the 1280 x 800 res of my screen.

Thank you.

You need put your camera in a minimum distance from your object, in your case, the size of object from it's face.

Remember that camera factor changes according your window size
