Minor error in renderSphere

[Camouflager]

For some reason I was going through sphere code, and I found that there's a minor error.

Here's how the positions are generated:

LearnOpenGL/src/6.pbr/1.1.lighting/lighting.cpp

Lines 265 to 271 in 3e94252

	const unsigned int X_SEGMENTS = 64;
	const unsigned int Y_SEGMENTS = 64;
	const float PI = 3.14159265359f;
	for (unsigned int x = 0; x <= X_SEGMENTS; ++x)
	{
	for (unsigned int y = 0; y <= Y_SEGMENTS; ++y)
	{

Here's how the indices for the triangle strips were generated:

LearnOpenGL/src/6.pbr/1.1.lighting/lighting.cpp

Lines 284 to 302 in 3e94252

	bool oddRow = false;
	for (unsigned int y = 0; y < Y_SEGMENTS; ++y)
	{
	if (!oddRow) // even rows: y == 0, y == 2; and so on
	{
	for (unsigned int x = 0; x <= X_SEGMENTS; ++x)
	{
	indices.push_back(y * (X_SEGMENTS + 1) + x);
	indices.push_back((y + 1) * (X_SEGMENTS + 1) + x);
	}
	}
	else
	{
	for (int x = X_SEGMENTS; x >= 0; --x)
	{
	indices.push_back((y + 1) * (X_SEGMENTS + 1) + x);
	indices.push_back(y * (X_SEGMENTS + 1) + x);
	}
	}

However this does not work when X_SEGMENTS != Y_SEGMENTS. It currently only works because x and y are interchangeable.

let X_SEGMENTS=32 we get the following result:

I'm a big fan of this website and I hope it gets better in the future. I hope this issue helps.
