C++ (Cpp) CRotationMatrix::RotateVector Exemples

Exemple #1

Fichier : rendered_image_widget.cpp Projet : gitter-badger/mandelbulber2

CVector3 RenderedImage::CalcPointPersp(const CVector3 &point, const CRotationMatrix &rot, double persp)
{
	CVector3 vect;
	CVector3 out;
	vect = rot.RotateVector(point);
	out.x = vect.x / (1.0 + vect.y * persp);
	out.y = -vect.z / (1.0 + vect.y * persp);
	return out;
}

Exemple #2

Fichier : fractal_formulas.cpp Projet : orbitcowboy/mandelbulber2

void Mandelbulbulb4Iteration(CVector3 &z, const cFractal *fractal, sMandelbulbAux &aux)
{
	double rp = pow(aux.r, fractal->bulb.power - 1);

	double angZ = atan2(z.y, z.x) + fractal->bulb.alphaAngleOffset;
	double angY = atan2(z.z, z.x) + fractal->bulb.betaAngleOffset;
	double angX = atan2(z.z, z.y) + fractal->bulb.gammaAngleOffset;

	CRotationMatrix rotM;
	rotM.RotateX(angX * (fractal->bulb.power - 1));
	rotM.RotateY(angY * (fractal->bulb.power - 1));
	rotM.RotateZ(angZ * (fractal->bulb.power - 1));

	z = rotM.RotateVector(z) * rp;
