C++ (Cpp) GfxMathRadToDeg Examples

Example #1

File: SC_Styven.cpp Project: OperationKiwiPower/Styven_Creation

float SC_GetAngleVector(TGfxVec2 Direction)
{
	float hypothenuse = Direction.Length();
	float fAngle = GfxMathRadToDeg(acos(Direction.x / hypothenuse));

	if (Direction.y > 0) return -fAngle;
	return fAngle;
}

Example #2

File: SC_Styven.cpp Project: OperationKiwiPower/Styven_Creation

float SC_GetAngleVector(TGfxVec2  & Position, TGfxVec2 Direction)
{
	TGfxVec2 Vecteur(Direction - Position);

	float hypothenuse = Vecteur.Length();
	float fAngle = GfxMathRadToDeg(acos(Vecteur.x / hypothenuse));

	if (Vecteur.y > 0) return -fAngle;
	return fAngle;
}

Example #3

File: TColor.cpp Project: DynalitykStudio/C-Project

TColor TColor::ShiftHue(const float fDeg)
{
	float fHueAngle = GfxMathRadToDeg(atan2(sqrt(3.0f) * (g - b), 2 * r - g - b));
	if (fHueAngle < 0.0f)fHueAngle += 360.0f;

	TColor tTemp = TColor::Hue(fHueAngle + fDeg);

	float fMin = (r < g) ? r : g;
	fMin = (fMin < b) ? fMin : b;

	float fMax = (r > g) ? r : g;
	fMax = (fMax > b) ? fMax : b;

	tTemp.r = tTemp.r * (fMax - fMin) + fMin;
	tTemp.g = tTemp.g * (fMax - fMin) + fMin;
	tTemp.b = tTemp.b * (fMax - fMin) + fMin;
	//tTemp.a = tTemp.a * (fMax - fMin) + fMin;

	return tTemp;
}
