This really puts a dampening on the learning if I cant even load a texture in without an error. The code posted here is from a tutorial over at the blitzmax wiki... Everything else goes ok, just this texfrompixmap command errors out. The texture is a 256x256 png

Hanging out in the opengl programming forum will be a complete waste of time as the previous post is 23 hours old, and down from that, 3 days, 1 week, and so on.... I need an answer asap to continue the learning otherwise I am at a complete standstill....

Please assist!

Did you run it? Did it work for you?

The reason I am so buggered on this is because I can't really sit and learn how to do proper 3D opengl in Blitzmax if I can't even load a texture.. A world without textures is rather boring... And I dont want to move on to more advanced topics since they involve textures as well...

Thanks for the reply, but I am still just as frustrated, and still discouraged over this...

I can run opengl windows just fine. I can get through all the NEHE tutorials that dont require textures.. But this GLTexFromPixmap is just killing me here...

So the question is why.... Going to figure it out tomorrow, i am dead tired from trial and error tonight.

Yan	(Posted 2005) [#11]

Did you run it? Did it work for you?

Your version doesn't, my version does (if I comment out the SetGraphics() command, I get the 'Unable to calculate tex size' error).

That picture isn't showing the code I posted!

Also, isn't BGL_DEPTHBUFFER throwing an error for you?
It does for me.

DH	(Posted 2005) [#12]

Your version doesn't, my version does (if I comment out the SetGraphics() command, I get the 'Unable to calculate tex size' error).

I just pasted your code in (the entire thing just to say to myself that I tried it your way), and I get the same error.

That picture isn't showing the code I posted!

Because your code states "'above 3 line can be replaced with : GLGraphics 640,480,0,60, GRAPHICS_BACKBUFFER | GRAPHICS_DEPTHBUFFER
'...aparently :o)", so i figured I would try it that way as well.

Also, isn't BGL_DEPTHBUFFER throwing an error for you?
It does for me.

Oddly enough, it isnt throwing an error. In fact, I can run all the stuff without textures with it (strange). I am running 1.14 and did a fresh synmods before I started this thread.

Seems either your Blitzmax is different than mine, or there is some other issue.

At least the nehe tutorials work (with the minor modifications for the new glgraphics and what not). So I can continue on the lessons. But it still leaves me to wonder if it will work the same at home as well (I am at work currently). This is somewhat disturbing.

Sorry, would rather burn in hell. Besides, I can't ask every enduser to have SP2 either. SP1 is one thing, but SP2 is nothing but crap....

and updating you graphics drivers too...

I don't see why my graphics drivers are allowing the way he is doing the NEHE tutorial to work, but not the simple opengl tutorial over at the wiki to work....... Do you?

Floyd

(Posted 2005) [#15]

Oddly enough, it isnt throwing an error.

It will if you put Strict at the top of your code.

With Strict you should get a message that BGL_DEPTHBUFFER is not found.
Without Strict a new variable named BGL_DEPTHBUFFER will be created and given a value of 0.

Yes its where you implementation of opengl comes from.
the nehe examples are fairly out of date now, are there any particular ones your having problems with? I have some of them converted...

REDi	(Posted 2005) [#19]

Just replace

CreateGraphics( 640,480,0,60,GRAPHICS_BACKBUFFER | BGL_DEPTHBUFFER )

With

GLGraphics( 640,480,0,60,GRAPHICS_BACKBUFFER | BGL_DEPTHBUFFER )

Using the code from your original post, works fine here.

Sveinung

(Posted 2005) [#20]

You mean

from:
CreateGraphics( 640,480,0,60,GRAPHICS_BACKBUFFER | BGL_DEPTHBUFFER )

To:
GLGraphics( 640,480,0,60,GRAPHICS_BACKBUFFER | GRAPHICS_DEPTHBUFFER )

I hope... :)

DEP is very nice. Security Center and Firewall improvements are less nice, but nice nonetheless.

you must be missing a whole bunch of updates lol!

Updates are still coming out for SP1.

I've only seen one computer ever refuse to boot up after upgrading to SP2.

Unfortunately it was my own.

Mine didn't refuse to boot, but the HTTP: protocol was completely routed. Get it? Routed? Never mind.

Anyways, that was on a 3 year old machine, on brand new installs it works perfectly...

H&K	(Posted 2006) [#25]

@ First Post

You are Creating a graphic Object but not selecting it
Change second line to

SetGraphic (CreateGraphics( 640,480,0,60,GRAPHICS_BACKBUFFER | BGL_DEPTHBUFFER ))

ImaginaryHuman

(Posted 2006) [#26]

Or just use GLGRaphics() by itself.

Also I seem to remember that the "unable to calculate texture size" error has something to do with the screen not being opened or not being supported by your hardware, more than anything whatsoever actually to do with textures.

H&K	(Posted 2006) [#27]

Its An error in GLAdjustTexSize called by GLTexFromPixmap.

I Agree that Saying use GLGraphics is a good answer, but that wouldnt explain what Dark had done wrong, which was that they were createing a graphic object, and not setting it as the one to use

Its not just an answer for Dark thou is it?
Its also for the next time someone has this error,(which happened to me Yestrday).
So it doesnt matter How old the thread is. Its still there to be searched.

LOL. Ok maybe
But I did honsetly mean my post to be for anyone else who was getting the error and not just dark.
It is an easy thing to do, (well I have done it at least twice). And the error message never points to where you havent rememberd to select the graphics object you have created;(

And the error "Unable to calculate tex size", doesnt give much clue to the fact you made the misstake in the first 3 lines of code.

I honestly cut GLAdjustTexSize and GLTexFromPixmap from the source and put it in my program adding loads of console prints all over the place.

It was only after I had given up on trying to call it that I got an error message that led me to realise my mistake.
