示例1: renderOffScreen
void CTargetingComputer::renderOffScreen()
{
// Perform offscreen rendering
CTexture* pTexture = g_oTextureManager.texture(m_auiOffScreenTexture);
pTexture->preRenderToTexture();
// Clear screen
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
// Calculate direction vector
CVector3 vecTarget = m_pTarget->m_ppMasses[0]->m_vecPos - m_pPlayerShip->m_ppMasses[0]->m_vecPos;
float fRange = vecTarget.length();
float fSize = m_pTarget->m_oModel.boundingSphere().m_fRadius;
// Set Projection Matrix
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
//gluPerspective(fAngle,1.0f,fRange-fSize, fRange+fSize);
glOrtho(-fSize,fSize,-fSize,fSize,fRange-fSize,fRange+fSize);
// Set Modelview Matrix
