Support / side-by-side 3D model Viewer and Comparator
« on: November 30, 2015, 07:23:42 pm »
Hey friends,

I am a new user of JPCT. I had a topic some month later:,4379.msg30466.html#msg30466

in that topic, I was going to develop a "side-by-side 3D model viewer". (please see the attached image); two models should be placed side-by-side and I want those similar models rotate simultaneously around their axis As I drag the mouse to left or right.

Now I need to know how to start. I have developed a simple 3d model viewer thanks to JPCT and helps of Dear EgonOlsen.

But I do not have enough knowledge to continue the project. for example based on the recommendation of EgonOlsen I tried to understand blitting (topic mentioned above), but I couldn"t understand what does that function really do and what's the relation to side by side viewing the models!!:(

Please help me.

Support / new JPCT user - receiving error in the first steps

Hi guys,

in the first steps of coding a Java program which uses JPCT, I encounter this error, could you help me please?
machine: Laptop Sony VAIO VGN-FW 190
Display Adapter: Mobile Intel(R) 45 Express Chipset family (Microsoft Corporation WDDM 1.1)
my graphics drivers are up to date.
I am waiting for help of one of JPCT forum users and maybe changing the current IDE from Netbeans to Eclipse. but I do not think this error depends on the current IDE I am using.

Support / new to JAVA and JPCT - how to create a 3d model viewer?
« on: May 13, 2015, 11:54:37 am »
Hi guys,
I am new to JAVA but have done programming and coding in VB and c#.
I want to create a simple windows-based application for loading, viewing and rotating 3d models with textures.
How should I do that using JPCT?
I have downloaded and installed JDK and Netbeans. how should I start? the Netbeans environment is very different from VB environment. moreover the JPCT wiki has some explanations that I don't understand. for example:

"The 3D engine itself is one jar only (jpct.jar). It can be found in the distribution's lib-directory. Just include that jar into your classpath and you are ready to compile and/or run jPCT applications."
what is classpath?

please give me a clue to start.
Many thanks
