示例1: render
void PostProcessSample::render(float elapsedTime)
{
Rectangle defaultViewport = Game::getInstance()->getViewport();
// Draw into the framebuffer
Game::getInstance()->setViewport(Rectangle(FRAMEBUFFER_WIDTH, FRAMEBUFFER_HEIGHT));
FrameBuffer* previousFrameBuffer = _frameBuffer->bind();
clear(CLEAR_COLOR_DEPTH, Vector4::zero(), 1.0f, 0);
_scene->visit(this, &PostProcessSample::drawScene);
// Bind the current compositor
Game::getInstance()->setViewport(defaultViewport);
Compositor* compositor = _compositors[_compositorIndex];
FrameBuffer* compositorDstFrameBuffer = compositor->getDstFrameBuffer();
FrameBuffer* prevToCompositeFrameBuffer = NULL;
if (compositorDstFrameBuffer)
{
prevToCompositeFrameBuffer = compositorDstFrameBuffer->bind();
}
else
{
prevToCompositeFrameBuffer = previousFrameBuffer->bind();
}
Game::getInstance()->clear(CLEAR_COLOR, Vector4(0, 0, 0, 1), 1.0f, 0);
compositor->blit(defaultViewport);
drawFrameRate(_font, Vector4(0, 0.5f, 1, 1), 5, 1, getFrameRate());
