Updates this grid with another source in a certain area.
Use it for example to add spheres as a brush.
| operation | The operation to use, will use this source and the other given one as operands. Beware that this function overrides the maybe existing sources in the operation. |
| source | The other source to combine this one with. |
| center | The rough center of the affected area by the operation. If the other source is a sphere, take its center for example. |
| radius | The radius of the affected area. For the example sphere, you might use its radius times two because the density outside of the sphere is needed, too. |
| Real Ogre::Volume::GridSource::getVolumeSpaceToWorldSpaceFactor | ( | void | ) | const |
Overridden from VolumeSource.
