Applies changes made to the 3D system.
This function must be called to apply any changes made with BASS_Set3DFactors, BASS_Set3DPosition, BASS_ChannelSet3DAttributes or BASS_ChannelSet3DPosition. This allows multiple changes to be synchronized, and also improves performance.
This function applies 3D changes on all the initialized devices. There is no need to re-call it for each individual device when using multiple devices.
BASS_ChannelSet3DAttributes, BASS_ChannelSet3DPosition, BASS_Set3DFactors, BASS_Set3DPosition
