Function documentation

std::shared_ptr<LineRenderer> fast::LineRenderer::create(Color color, float lineWidth, bool drawOnTop)

Create instance.

color Color of lines to draw
lineWidth Width of line
drawOnTop Whether to draw on top of everything else or not. This disables the depth check in OpenGL
Returns instance

uint fast::LineRenderer::addInputConnection(DataChannel::pointer port) override

Returns the input nr of the new connection

Adds a new input connection

void fast::LineRenderer::setDefaultLineWidth(float width)

Set line width in percent (2D mode only atm.)
