void LaxInterfaces::ColorPatchInterface::drawControlPoint ( int i )

virtual

Draw a single point as a little filled colored circle.

This is for the hoverpoint, and is called from PatchInterface::Refresh().

Reimplemented from LaxInterfaces::PatchInterface.

References LaxInterfaces::anInterface::dp, Laxkit::Displayer::drawpoint(), Laxkit::Displayer::DrawReal(), Laxkit::Displayer::DrawScreen(), Laxkit::Displayer::NewFG(), Laxkit::pixelfromcolor(), and Laxkit::Displayer::realtoscreen().

void LaxInterfaces::ColorPatchInterface::drawpatch	(	int	roff,
		int	coff
	)

virtual

Draws one patch.

called by drawpatches(). The whole patch is made of potentially a whole lot of adjacent patches. If rendermode==0, then just draw the wire outline. Otherwise do the whole color thing.

This function prepares up col1,col2,col3,col4 and Cx,Cy matrices for patchpoint2().

roff,coff is which patch, point start is == xoff*3

Reimplemented from LaxInterfaces::PatchInterface.

References LaxInterfaces::B, LaxInterfaces::anInterface::dp, LaxInterfaces::PatchData::getGt(), LaxInterfaces::m_times_m(), patchpoint2(), Laxkit::Displayer::realtoscreen(), and LaxInterfaces::PatchInterface::rendermode.

void LaxInterfaces::ColorPatchInterface::patchpoint	(	PatchRenderContext *	context,
		double	s1,
		double	t1,
		double	s2,
		double	t2
	)

protectedvirtual

Todo:: **** mondo problems with this one, keeps recursing forever

References Laxkit::coloravg(), LaxInterfaces::anInterface::dp, Laxkit::Displayer::drawpoint(), LaxInterfaces::PatchRenderContext::getPoint(), LaxInterfaces::getT(), Laxkit::Displayer::NewFG(), and Laxkit::pixelfromcolor().

void LaxInterfaces::ColorPatchInterface::patchpoint2 ( PatchRenderContext * context )

protectedvirtual

No recursion, just draw n s,t rects for patch.

Assumes col1,col2,col3,col4 are already set to the approprate colors for the current segment.

Todo:: optimize this a la imagepatchinterface....

References Laxkit::coloravg(), LaxInterfaces::anInterface::dp, Laxkit::Displayer::drawlines(), Laxkit::Displayer::DrawReal(), Laxkit::Displayer::DrawScreen(), LaxInterfaces::PatchRenderContext::getPoint(), LaxInterfaces::getT(), Laxkit::Displayer::NewFG(), and Laxkit::pixelfromcolor().

Referenced by drawpatch().

int LaxInterfaces::ColorPatchInterface::sendcolor ( Laxkit::ScreenColor * col )

protectedvirtual

Send a "make curcolor" event to the viewport.

Todo:: bit of a hack here.
