[LIBGDX][SOLVED] Need optimize load images

Newbie & Debugging Questions
#1

I have background, his size 20000x20000 pxl’s, consisting from 33 random repeat images 1000x1000 pxl’s.
At the beginning I try load images as Texture from files, but my pc freezes. I create json with params, and texture atlas, load as Image and build… it take 3 fps. I change filter from texture pack from Linear to Nearest, but it not take effect. How I can up perfomance? Correctly load background images via scenes.scene2d.ui.Image?

#2

do you render the complete background?

#3

Do you need to draw them all at the same time? If not, loading each of them as seperate texture should solve your problem.

#4

Yes I load background complete, I need to draw them only in my viewport, how I can separate?

#5

Show your code.

#6

Have a look at culling, google it.

You are probably experiencing low FPS because you are rendering a ton of stuff not even visible to the camera. Culling allows you to render things only visible in the viewport.

#7

This is my actor (part/component background), I try optimize with frustum, and take 10fps. I correctly use frustum? In camera i see 4 sprite, where I mistake?


	private TextureRegion sprite;
	private Stage stage;

	public Space(Stage s, MapJsonReader m, Skin skin) {
		stage = s;
		sprite = skin.getRegion(m.name);

		setBounds(
			m.x, m.y,
			sprite.getRegionWidth(),
			sprite.getRegionHeight()
		);
		setName("space");
		stage.addActor(this);
	}

	@Override
	public void draw(SpriteBatch batch, float parentAlpha){
		if(stage.getCamera().frustum.boundsInFrustum(new BoundingBox(
			new Vector3(getX(), getY(), 0),
			new Vector3(getY()+sprite.getRegionWidth(), getY()+sprite.getRegionHeight(), 0)
		))){
			batch.draw(
				sprite,
				getX(),
				getY()
			);
		}
	}

Resize texture from 1000x1000 to 500x500, I take 60fps, problem solved. See mip mapping http://www.badlogicgames.com/wordpress/?p=1403
