Hello.

Excuse me, if the same question has been already asked, but i haven't found it here.
I've got two objects: one is semi-transparent, another one is not. When standing near to those objects, everything looks ok:


but when stepping back, the one that has to be behind, passes through the nearer one:


changing glZBufferDepth in Config didn't make any effect. So how can i avoid this?
Thank you.

check your mail, Melssj5

A font is a solution, i used it in j2se with success, but I haven't tried it in mobile java. And yes, i think it would be too expensive for a mobile device to store images for each char. I have a good document that describes EAN construction algorhythm at work. Besides, barcode construction algorhythms are quite similar for some groups of barcodes, so i can send this doc to you tommorow, if you need it.

Hello, i've had a similar task once. And my solution was not to search for apis, but to code it myself  It's not so hard, you just have to read UPC or EAN documentation, all algorhythms are described there.

Hey, I've tested the same code on NVidia GeForce 2 MX 400 and the same problem occurred. That is, i can not init buffer with AA. When passing AA_2X or AA_4X to FrameBuffers' constructor, i see the same picture as without AA.

No, i am making a simple metaverse, something similar to aptalkarga. Maybe, in the future the project will grow into something more complicated, maybe not

I can do so, of course, and i already have nvidia at home. But this app is developed for ordinary people, and big percent of those buy a pc with on-board-everything  so i think that i should better use sw renderer..

enableGLCanvasRenderer ... look at the GL word. it means it uses OPEN GL, that means hardware renderer. if you want to hace software render on a canvas just put the render stuff on the paint methos over an awt canvas. There are some examples over there. On the download section, there is a project called Maze, it was my first jpct applet, it may help you.

Thanks, Melssj5. I understood. how could i have missed that..

Now about hardware renderer. Here is a screenshot done at 640x480 and SAMPLINGMODE_NORMAL:


when switching to AA_2X or AA_4X no error message occurs and i see a blank screen or exactly the same picture as with SAMPLINGMODE_NORMAL. The application is developed and tested on an on-board Intel 82915G/GV/910GL VGA with the latest drivers from Intel.

You are using the AWTGLCanvas-Renderer? If so, AA (i.e. the sampling mode) depends on your hardware. Which graphics card is that and do you have a screen shot?

Yes, it is AWTGLCanvas-Renderer. I'll make a screenshot a bit later..

karga uses the software renderer, that's a different thing.

Ok, another question: How can i make a canvas renderer use software renderer mode? Because when i try to do the following:

canvas = buffer.enableGLCanvasRenderer(IRenderer.RENDERER_SOFTWARE);

it is the same as buffer.enableGLCanvasRenderer(IRenderer.MODE_LEGACY), as i understand, and LEGACY renderer is no longer supported

Hello.

I am using a canvas renderer. Can I set sampling mode other than SAMPLINGMODE_NORMAL and how?
I've tried both setting mode to SAMPLINGMODE_GL_AA_2X and SAMPLINGMODE_GL_AA_4X, but that didn't make any effect. Although i saw that aptalkarga uses canvas renderer, too, and a user can switch between sampling modes there.

any help will be appreciated.
