SetRotationMode()

static void SRL::VDP2::RBG0::SetRotationMode ( VDP2::RotationMode mode, bool vblank = true )

inlinestatic

Select what type of rotation to use for the rotating scroll (Call before Loading RBG0)

Parameters

mode	The RotationMode to use for this scroll
vblank	Chose to update VRAM at VBLANK to reduce amount of coefficient data required for rotation of a plane (default = true)

Note

when 2 or 3 axis rotation is Selected, VRAM will be allocated to store necessary coefficient data. If Vblank is set false, all coefficients will be statically stored in VRAM as a 0x18000 byte table. If Vblank is set true, only the coefficients necessary for the current frame will be dynamically written to VRAM at Vblank, reducing VRAM footprint to 0x2000 bytes per rotation parameter but increasing required Vblank overhead.
