Function Documentation

ComputePinCenterScreen()

ImVec2 Olympe::NodeGraphShared::ComputePinCenterScreen ( int  nodeId, const BTNodeLayout *  layout, bool  isOutput, float  pinOffset, float  headerHeight, float  zoom  )

inline

Compute the screen-space center position of a pin.

Calculates where a pin should be rendered on screen, accounting for:

• Node screen position and dimensions
• Pin type (input/output)
• Header offset
• Zoom level

Parameters

nodeId	The ImNodes node ID
layout	The node's layout information (optional, used for validation)
isOutput	True for output pin (right side), false for input pin (left side)
pinOffset	Horizontal offset from node edge (from ImNodes::GetStyle().PinOffset)
headerHeight	Height of the node header in pixels (pins are positioned below header)
zoom	Current zoom level (affects spacing)

Returns

ImVec2 The screen-space center position of the pin

DrawPinCircle() [2/2]

void Olympe::NodeGraphShared::DrawPinCircle	(	ImDrawList *	drawList,
		const ImVec2 &	center,
		float	radius,
		uint32_t	color,
		uint32_t	outlineColor,
		float	outlineThickness
	)

Draw a pin circle with outline.

Renders a circular pin with two layers:

• Outer circle (outline) for contrast
• Inner circle (main color)

Parameters

drawList	ImGui draw list to render to
center	Center position of the pin in screen space
radius	Inner radius of the pin
color	Inner circle color (RGBA)
outlineColor	Outline color (RGBA)
outlineThickness	Thickness of the outline in pixels
