[Solved][LWJGL3]Can't get Frustum Culling to Work

Newbie & Debugging Questions
#1

I’ve tried lots of resources, such as the lighthouse3d tutorials (and more tutorials) and also Frustum classes that i’ve found on the internet. None of which have worked for me.

Note: before i show code i will note i am using JOML(Java OpenGl Math Library) for Vectors and Matrices, etc.

Here is the current Version that doesnt work(found it on internet and modified it): http://pastebin.com/CqtnXmag
Originally instead of:

Window.projectionMatrix.get(projectionBuffer);

it was:

glGetFloat(gl_projection_matrix, projectionbuffer)

and the same with the modelviewbuffer.

Window.projectionMatrix is created at the start of the window initialization class via:

public static Matrix4f updatePerspective(float fov, float aspect, float zNear, float zFar){
         Matrix4f matrix = new Matrix4f().identity();
		
         matrix.setPerspective(fov, aspect, zNear, zFar);
         perspective = matrix;
         return matrix;
}

and MatrixUtils.getmodelview() and matrixutils.getViewMatrix():

public static Matrix4f getViewMatrix(Camera camera){
		Vector3f cameraPos = camera.getTransform().getPosition();
		Quaternionf rotation = camera.getTransform().getRotation();
		
		Matrix4f viewMatrix = new Matrix4f().identity();
		//First do the rotation so camera rotates over its position
		viewMatrix.rotate((float)Math.toRadians(rotation.x), new Vector3f(1, 0, 0))
					.rotate((float)Math.toRadians(rotation.y), new Vector3f(0, 1, 0));
		//Then do the translation
		viewMatrix.translate(-cameraPos.x, -cameraPos.y, -cameraPos.z);
		return viewMatrix;
	}

	public static Matrix4f getModelViewMatrix(Transform transform, Matrix4f viewMatrix){
		Quaternionf rotation = transform.getRotation();
		Matrix4f modelViewMatrix = new Matrix4f().identity().translate(transform.getPosition())
						.rotateX((float)Math.toRadians(-rotation.x))
						.rotateY((float)Math.toRadians(-rotation.y))
						.rotateZ((float)Math.toRadians(-rotation.z))
						.scale(transform.getScale());
		Matrix4f viewCurr = new Matrix4f(viewMatrix);
		return viewCurr.mul(modelViewMatrix);
	}

Then (just to test) i am doing this every render call (for two cubes):

public void render(Window window, List<GameObject> renderList, Frustum frustum) {
		
		for(GameObject gameObject : renderList){
			frustum.calculateFrustum(camera);
			if(frustum.cubeInFrustum(gameObject.getTransform().getPosition().x, gameObject.getTransform().getPosition().y, gameObject.getTransform().getPosition().z, 1)){
				System.out.println("in frustum");
			}
			Matrix4f modelViewMatrix = MatrixUtils.getModelViewMatrix(gameObject.getTransform(), viewMatrix);
			shaderProgram.setUniform("modelViewMatrix", modelViewMatrix);
			shaderProgram.setUniform("material", gameObject.getMesh().getMaterial());
			gameObject.render(window, shaderProgram);
		}
	}

I don’t know whats wrong :frowning:
