An OBJ file with a spline

[abrzozowski]

Hi @pradeep-pyro,

Which program did you use to visualize OBJ files with a spline?

Hi @abrzozowski
When I tried this code, I was able to open the resulting obj files as surfaces in Rhino. However, when I opened them in Blender, only dots appeared. It seems Blender isn't capable of opening obj files containing Nurbs surfaces.

	auto srf = getHemisphere();  // coimng from test_rational_surface.cpp file
	float v = 0.25f;
	tinynurbs::RationalSurface3f left, right;
	std::tie(left, right) = tinynurbs::surfaceSplitV(srf, v);
	
	bool is_valid_l = tinynurbs::surfaceIsValid(left);
	bool is_valid_r = tinynurbs::surfaceIsValid(right);
	
	auto outLeftfile = ofToDataPath("untitled_Leftout.obj", true);
	auto outRightfile = ofToDataPath("untitled_Rightout.obj", true);
	tinynurbs::surfaceSaveOBJ(outLeftfile, left);
	tinynurbs::surfaceSaveOBJ(outRightfile, right);
