示例1: renderViewport
void Renderer::renderViewport( Viewport& viewport )
{
Texture* rt = viewport.getRenderTarget();
if( rt )
rt->bindAsRenderTarget( true ); //TODO guess if this viewport doesn't render 3D layers to save memory?
else
glBindFramebuffer( GL_FRAMEBUFFER, 0 );
glFrontFace( rt ? GL_CW : GL_CCW ); //invert vertex winding when inverting the view
currentState.targetDimension.x = (float)(rt ? rt->getWidth() : width);
currentState.targetDimension.y = (float)(rt ? rt->getHeight() : height);
glViewport(0, 0, (GLsizei) currentState.targetDimension.x, (GLsizei)currentState.targetDimension.y);
//clear the viewport
if (viewport.getClearEnabled()) {
glClearColor(
viewport.getClearColor().r,
viewport.getClearColor().g,
viewport.getClearColor().b,
viewport.getClearColor().a);

}
currentState.view = viewport.getViewTransform();
