示例1: ChangeSize
/**
* Window has changed size, or has just been created. In either case, we need to use the window
* dimensions to set the viewport and the projection matrix.
*/
void ChangeSize(int w, int h)
{
glViewport(0, 0, w, h);
transformPipeline.setMatrixStacks(modelViewMatrix, projectionMatrix);
viewFrustum.setPerspective(35.0f, float(w) / float(h), 1.0f, 100.0f);
projectionMatrix.setMatrix(viewFrustum.GetProjectionMatrix());
modelViewMatrix.identity();
}示例2: ChangeSize
/**
* Window has changed size, or has just been created. In either case, we need to use the window
* dimensions to set the viewport and the projection matrix.
