Switch between Orbit - Thirdperson Camera's

#1 Try using getTransform and setTransform instead of setPosition. This provides a full matrix of the camera position, and might work out better for you.

#2 I tried getTransform/setTransform but this does not work. The problem is, I think, that the orbit cam uses spherical coordinated (azimuth, declination, zoomdistance) and the 3the person cam Cartesian coordinates (xyz). But I cant figure out how to align them.

#3 Roger that. I tried getTransform/setTransform too, without effect.

#4 I'have found a way to center the camera behind the player when you switch to the orbit camera mode:

Replace the "case Orbitmode :" in the advanceTime function with this:

case OrbitMode :
		{
			if ( playerObj != NULL)
			{
				Point3F mConvertedOrbitOffset;
				F32 mOffsetX;
				F32 mOffsetY;
				F32 mOffsetZ;

				MatrixF objToWorld = playerObj->getRenderTransform();
				objToWorld.mulP(mCurrentOrbitOffset, &cameraPosWorld);
                
				//Added for camera reset
				bool resetCam = Con::getBoolVariable("$advCamera::resetOrbitCam", false);
				if (resetCam)
				{
					Con::setBoolVariable("$advCamera::resetOrbitCam", false);
					Player*	playerObjAsPlayer =	dynamic_cast<Player*>(playerObj);			
					Point3F	Rotation = playerObjAsPlayer->getRotation();
					mAzimuth = mAzimuth - (mAzimuth - ((-Rotation.z) + (1.5 * M_PI)));
				}
				//Added for camera reset

		                // use spherical to cartesian coord transforms to calculate offset
				mOffsetX = mZoomDistance * sin(mDeclination) * cos(mAzimuth);
				mOffsetY = mZoomDistance * sin(mDeclination) * sin(mAzimuth);
				mOffsetZ = mZoomDistance * cos(mDeclination);
				mConvertedOrbitOffset.set(mOffsetX, mOffsetY, mOffsetZ);
				cameraPosWorld += mConvertedOrbitOffset;
			}
			break;
		}

Put "$advCamera::resetOrbitCam = true;" in your script to reset the camera.

This aligns only the azimuth not the declination and zoomdistance. Can someone point me in the right direction for calculating the correct declination and zoomdistance?

Thanx,
Klaas

#5 I'm just back from vacation... :-)

Big thanks for this info Klaas! Which sorce file have you modified?

#6 Chris, I modified the advancedCamera.cc source file.
