just a simple problem :(

I'm messing around with ogre just to get the hang of it, and I wanted to jsut place a simple model, the model is about 20 units long... here is my code:

Code: Select all

#include <iostream>
#include <string>
#include <windows.h>

#include "Ogre.h"
using namespace Ogre;

int main() {
	Root* root = new Root();

	if(!root->showConfigDialog())
		return -1;

	ConfigFile file;
	String type, arch;
	file.load("resources.cfg");
	ConfigFile::SettingsIterator i = file.getSettingsIterator();

	while(i.hasMoreElements()) {
		type = i.peekNextKey();
		arch = i.peekNextValue();

		Ogre::ResourceManager::addCommonArchiveEx(arch, type);
		i.getNext();
	}

	RenderWindow* window = root->initialise(true);
	SceneManager* smgr = root->getSceneManager(ST_GENERIC);
	InputReader* inputDevice = PlatformManager::getSingleton().createInputReader();
	inputDevice->initialise(window);

	Camera* camera = smgr->createCamera("testCamera11");
	window->addViewport(camera);

	camera->setPosition(Vector3(0.0, 0.0, 20.0));
	camera->lookAt(0.0, 0.0, 0.0);

	Entity* test = smgr->createEntity("mg", "mg.mesh");
	SceneNode* testNode = smgr->getRootSceneNode()->createChildSceneNode();
	testNode->attachObject(test);
	smgr->setAmbientLight(ColourValue(1.0, 1.0, 1.0));

	while(1) {
		MSG msg;

		while(PeekMessage(&msg, NULL, 0U, 0U, PM_REMOVE)) {
			TranslateMessage(&msg);
			DispatchMessage(&msg);
		}

		if(!root->_fireFrameStarted())
			break;

		root->_updateAllRenderTargets();

		if(!root->_fireFrameEnded())
			break;

		inputDevice->capture();

		if(inputDevice->isKeyDown(KC_ESCAPE))
			break;
	}

	delete inputDevice;
	delete root;
	return 0;
}

but nothing shows up at all!?! just blackness

here is the log...

any ideas? thanks

Try to reduce the position of the near clipping plane of the camera:

Code: Select all

camera->setNearClipDistance(10.0)

By default, it is set to 100 (in the constructor of Ogre::Camera).

You said the object was 20 units big and you have the camera sitting exactly 20 units away from that object. Could it be you are actually inside your mesh?

it was the camera clipping distance that was the problem.... thanks for your guys help!
