示例1: UpdatePointMotion
//----------------------------------------------------------------------------
void ParticleController::UpdatePointMotion (float fCtrlTime)
{
Particles* pkParticle = (Particles*) m_pkObject;
int i, iVertexQuantity = pkParticle->GetActiveQuantity();
float* afSize = pkParticle->Sizes();
for (i = 0; i < iVertexQuantity; i++)
{
float fDSize = fCtrlTime*m_afPointSizeChange[i];
afSize[i] += fDSize;
}
Vector3f* akVertex = pkParticle->Vertices();
for (i = 0; i < iVertexQuantity; i++)
{
float fDistance = fCtrlTime*m_afPointLinearSpeed[i];
Vector3f kDTrn = fDistance*m_akPointLinearAxis[i];
akVertex[i] += kDTrn;
}
Vector3f* akNormal = pkParticle->Normals();
if ( akNormal )
{
for (i = 0; i < iVertexQuantity; i++)
{
float fAngle = fCtrlTime*m_afPointAngularSpeed[i];
Matrix3f kDRot(m_akPointAngularAxis[i],fAngle);
akNormal[i] = kDRot*akNormal[i];
// TO DO. Since the normals are being updated in-place, after a
// few rotations the numerical errors might build up. The
// unitizing is designed to fix the errors in length. Arrange
// for this to happen on a less frequent basis.
akNormal[i].Normalize();
}
