{
ApplyColorAndOpacityProperties(renderer);
DataNode * node = GetDataNode();
if(node == NULL)
{
return;
}
node->GetBoolProperty("draw normals 2D", m_DrawNormals, renderer);
// check for color and opacity properties, use it for rendering if they exists
node->GetColor(m_LineColor, renderer, "color");
node->GetOpacity(m_LineColor[3], renderer, "opacity");

{
float rgba[4] = {1.0f, 1.0f, 1.0f, 1.0f};
DataNode *node = GetDataNode();
// check for color prop and use it for rendering if it exists
node->GetColor(rgba, renderer, "color");
// check for opacity prop and use it for rendering if it exists
node->GetOpacity(rgba[3], renderer, "opacity");
double drgba[4] = {rgba[0], rgba[1], rgba[2], rgba[3]};
