Support / Re: Advices about possible project
« on: February 12, 2014, 01:47:04 am »
Is ti posible to generate a poligon by having the corners of that poligon and use it as a plane to apply a texture over it?

I mean, lets imagine I have this set of coordinates:


(20, 50)
(25, 36)
(15, 85)
(12, 65)
(65, 5)
etc etc etc

How can I draw a poligon model that uses all that points????

Hi Guys, I have been out of JPCT for years, now I was asked to do a software (Maybe for android but could be done in java too) that requires image processing, so Immediately I came here to ask.

One of the app requirements are:

 - Take a pic with an android device, then you could select the floor or even a wall and change it texture, all this from an android device, any image post processing  could be done on a server if necessary.

How do you think this could be achieved? ANy advices will be very appreciated. Becausse I must give an answer soon.

« on: September 16, 2009, 04:37:29 pm »
Well, having another word just for rendering the horizon would work. you just have to call the rendering methods to have the framebuffer filled with that information, and then render the other world without clearing the framebuffer.


You can also have a cube with a texture like the horizon, and a secundary camera inside that cube, render that secundary camera into the frameBuffer and then render your game without clearing the framebuffer.

I guess is due to the name of the texture file

Nonebrown.jp

12 chars

3DS files stores texture names in 8.3 format

inside the map, the referenced texture name is Nonebrown.jp but the file is Nonebrown.jpg

Well, is not the big deal, but anyway, here are some pics, the whole app is at 75% I guess.







--> used my son teeth as a texture  ;D

Hi, I tested it on my laptop using firefox and IE and jre1.6.0_12. I runned it from another 2 machines and the GLCanvas doesnt appeared. Thats strange..... I put an IPaintListener on the FrameBuffer and put some outputs, on the machines that the glcanvas is visible the outputis being printed but ont eh other machines where the GLCanvas is not visible the output is not being printed. Something have to be buggy with it. Now I am using the software renderer which is more stable but is not as fast as I wish it were.

Hi, some news on the topic....

I made a copy of my applet and changed the exteds JApplet for JFrame and it runs great.... and it also ran well when chenged to sw rendering. I have not changed the Rendering Thread/EventManagmentThread just changed the JApplet for JFrame.

Should this be reported as a bug???? Only happens on Applets with GLCanvas.

I changed it to render in software instead of inside a GLCanvas (minor change) and the delay does not appear. COuld this be some issue the the new lwjgl with glCanvas????

Paul, the problem is not abouth that beucasse I was happening before adding that piece of code of the listener. Egon or Paul....Do you have a machine with Tomcat and mysql to send a test case??

Hi, ai am having problems with performance, from time to time (almost each 10 seconds) the CPU usage goes to 100% on the applet and then it stops responfing for 5 or 6 seconds, and then continues on the same way. Any ideas????

I am using a Centrino 1.6, 1Gb RAM, ATIX600, and I am running a GL Canvas inside an applet.


The code is quite simple, The class that does all the Rendering is:

Support / CHanging the memory usage by default?
« on: February 19, 2009, 05:36:26 pm »
Hi, I am having problems with running an app in java. I know I could use the -Xmx and -Xms params when calling to java.exe.

But I need to do something different, I need to chance the default memory usage rules for java. That means, that all the java apps will run with that memory specifications without needing to specify it for every program.

Is there any way to do it?
