示例1: sphericalRadius
void CCOrbitCamera::sphericalRadius(float *newRadius, float *zenith, float *azimuth)
{
float ex, ey, ez, cx, cy, cz, x, y, z;
float r; // radius
float s;
CCCamera* pCamera = m_pTarget->getCamera();
pCamera->getEyeXYZ(&ex, &ey, &ez);
pCamera->getCenterXYZ(&cx, &cy, &cz);
x = ex-cx;
y = ey-cy;
z = ez-cz;
r = sqrtf( powf(x,2) + powf(y,2) + powf(z,2));
s = sqrtf( powf(x,2) + powf(y,2));
if( s == 0.0f )
s = FLT_EPSILON;
if(r==0.0f)
r = FLT_EPSILON;
*zenith = acosf( z/r);
if( x < 0 )
*azimuth= (float)M_PI - asinf(y/s);
else
*azimuth = asinf(y/s);
*newRadius = r / CCCamera::getZEye();
