Camera with setViewMatrixAffector

[achpile]

Hi, guys! I need help with affector... The problem is in detection scene nodes in field of view of the camera with ViewMatrixAffector.



So, the "Scene node 2" isn't drawn because it's invisible by Camera without affector. May be it's a bug, or may be wrong sequence of my doings:

Code: Select all

/**
The camera is moved on -25
But the "drawn field of view" not
*/
 
driver->beginScene(true, true, irr::video::SColor(255, 0, 0, 0));
 
viewMatrix.makeIdentity();
viewMatrix.setTranslation(irr::core::vector3df(0, -25, 0));
cam->setViewMatrixAffector(viewMatrix);
smgr->drawAll();
 
driver->endScene();

Must admit I never used the setViewMatrixAffector. Maybe let's figure out first if it removes stuff because of culling. Can you for a test disable culling for your scenenode completely? You can do so with node->setAutomaticCulling(0).

nope, it's not culling

well, I missed some important thing.

It was something like this:

Code: Select all

 
irr::scene::ISceneNodeAnimatorCollisionResponse* collider = smgr->createCollisionResponseAnimator(
                selector, player->cam, irr::core::vector3df(25,50,25),
                irr::core::vector3df(0, -10.f,0),
                irr::core::vector3df(0,0,0), 0.005f);
 
driver->beginScene(true, true, irr::video::SColor(255, 0, 0, 0));
 
viewMatrix.makeIdentity();
viewMatrix.setTranslation(irr::core::vector3df(0, -25 + PLAYER_HEAD_TILT * sin(moving), 0));
cam->setViewMatrixAffector(viewMatrix);
smgr->drawAll();
 
driver->endScene(); 
 

So the problem appears. After I changed it to:

Code: Select all

 
irr::scene::ISceneNodeAnimatorCollisionResponse* collider = smgr->createCollisionResponseAnimator(
                selector, player->cam, irr::core::vector3df(25,50,25),
                irr::core::vector3df(0, -10.f,0),
                irr::core::vector3df(0,25,0), 0.005f);
 
viewMatrix.setTranslation(irr::core::vector3df(0, PLAYER_HEAD_TILT * sin(moving), 0));
 

And after that it becomes correct. (PLAYER_HEAD_TILT = 3.0f, so it's almost slight)
