[osg-users] Animation problem

[Julie Green]

Hi,
Can't figure out what is the problem. I'm trying to modify geometry depending on time. But I'm getting an exception "std::__non_rtti_object at memory location.." or application triggers a breakpoint.

Code:

void SurfaceCalculationThread::run()
{
	while (!done)
		reCalculateSurface();
};

float SurfaceCalculationThread::calculateZ(float x, float y, float t)
{
	float z;
	z = sqrt(((x*x) / (B*B)) + ((y*y) / ((A*A)*(sin(t)*sin(t)))) + 1);
	return z;
}

void SurfaceCalculationThread::reCalculateSurface()
{
	float x, y, z;
	int i = 0;
	float something = (sqrt(Npolygon) / 2)*1.00;
	t=time->elapsedTime_n();
	for (x = -something; x <= something; x += 1.0f)
	{
		for (y = -something; y <= something; y += 1.0f)
		{
			(*vertices2)[i].set((*vertices)[i]);
			z = calculateZ(x, y, t);
			(*vertices)[i].set(osg::Vec3f(x, y, z));
			i++;
		}
	}
	geometry->setVertexArray(vertices2);
	geometry->setUpdateCallback(new UpdateSurfaceCallback(vertices));
}





Thank you!

Cheers,
Julie
