Problem

I'm so sorry to ask the stupid question.
I can't find any document about "ogre java binding".
so i wrote a java tutorial application referenced from BasicTutorial.cpp.
i will be very appreciated,if any advice

Code

test.java

import org.ogre.*;

public class test {
    ApplicationContext applicationContext=null;
    InputListener inputListener=null;
    SceneManager sceneManager=null;
    ShaderGenerator shaderGenerator=null;
    Light light=null;
    SceneNode lightNode=null;
    Camera camera=null;
    SceneNode cameraNode=null;
    Entity ogreEntity=null;
    SceneNode ogreNode=null;
    public void init(){
        applicationContext=new ApplicationContext("fuck");
        inputListener=new InputListener();
        sceneManager=applicationContext.getRoot().createSceneManager();
        shaderGenerator=ShaderGenerator.getSingleton();
        light=sceneManager.createLight("MainLight");
        lightNode=sceneManager.getRootSceneNode().createChildSceneNode();
        camera=sceneManager.createCamera("mycam");
        cameraNode=sceneManager.getRootSceneNode().createChildSceneNode();
    }
    public void setup(){
        init();
        applicationContext.initApp();
        applicationContext.addInputListener(inputListener);
        shaderGenerator.addSceneManager(sceneManager);
        sceneManager.setAmbientLight(new ColourValue(0.5f,0.5f,0.5f));
        lightNode.attachObject(light);
        lightNode.setPosition(20f,80f,50f);
        camera.setNearClipDistance(5f);
        camera.setAutoAspectRatio(true);
        cameraNode.attachObject(camera);
        cameraNode.setPosition(0f,0f,140f);
        applicationContext.getRenderWindow().addViewport(camera);
    }
    public  void run(){
        try {
            setup();
            applicationContext.getRoot().startRendering();
            applicationContext.closeApp();
        }catch (Exception exception){
            System.out.println(exception.toString());
        }

    }
}

main.java

public class main {
    public static void main(String[] args) {
       test t=new test();
       t.run();
    }
}

Is there a way to do "render scaling" in Ogre? I.e. I want Ogre to render the scene in 1080p resolution but I want the final output to the monitor be upscaled to 4K.

Pavel Rojtberg

@paroj

this is trivial to do with a render_quad compositor

@SNiLD

Doesn't sound like it can be solved with simple render_quad compositor unless I'm missing something. If I understand correctly _createRenderWindow forces the resolution that Ogre uses for rendering the scene and no matter what value I give for target_width_scaled for the compositor, it will be scaled back to the size of the RenderWindow created.

hi guys

im trying to comple the tut1 src but im getiing

error C4996: 'Ogre::Light::setDirection': was declared deprecated

siN

@sindev95

nvm solved it

compositor DynamicResolution
{
    technique
    {
        texture scene 1920 1080 PF_BYTE_RGBA

        target scene
        {
            input previous
        }

        target_output
        {
            input none

            pass render_quad
            {
                material DynamicResolution
                input 0 scene
            }
        }
    }
}

@sindev95

do you guys have any idea how can i make a SceneManager where i have images for heights/walk/water which ill use to generate the scene based on ?

im still reading about octree

SNiLD

@SNiLD

TerrainSample in the sample browser does it like that

siN

@sindev95

ok ill take a look

@SNiLD can u gimme the path for the file ?

siN

@sindev95

is it samples/simple/include/terrain.h ?

SNiLD

@SNiLD

https://github.com/OGRECave/ogre/blob/master/Samples/EndlessWorld/include/EndlessWorld.h

oh yeah that wasn't from image though, it generates random noise at: https://github.com/OGRECave/ogre/blob/master/Samples/EndlessWorld/src/PerlinNoiseTerrainGenerator.cpp

but yeah instead of the noise you'd just read from the file

siN

@sindev95

ill try to work around that

cause there's a skybox

grass

tiles

path

water

..etc

spawn points

creatures

i want to take these into account

SNiLD

@SNiLD

can be done, Ogre::Terrain is surprisingly powerful

siN

@sindev95

strange that there aint much resources about ogre3d

the docs aren't good too

i have to go around the samples and the core to understand everything

SNiLD

@SNiLD

we use it in a simulation with 20km x 20km visibility to all direction with millions of trees, sea safety equipment, sea, city models, etc

siN

@sindev95

what is the octreescenemanager

SNiLD

@SNiLD

yeah, most stuff has to be done by reading the source code, although the documentation has improved a lot after paroj took over

it reads in the class definition

siN

@sindev95

would be much better if there's ytb tuts or more articles on it

i mean the engien

SNiLD

@SNiLD

we use the default scene manager as other really don't provide any improvement on open scenes

siN

@sindev95

@sercero

Check the wiki also

@sindev95

@SNiLD what i did for now is

Guillermo Ojea Quintana

@sercero

Octree Scene manager was though as an optimization, but eventually it was found out that culling by brute force was best

siN

@sindev95

create a SceneManagerCamera which is : public OctreeCamera

and the SceneManager is : public OctreeSceneManager

and play with'em
