Renderer.setViewPort介绍

[英]Set the viewport location and resolution on the screen.
[中]在屏幕上设置视口位置和分辨率。

代码示例

代码示例来源：origin: jMonkeyEngine/jmonkeyengine

int viewHeight = (int) ((curCamera.getViewPortTop() - curCamera.getViewPortBottom()) * curCamera.getHeight());
renderer.setViewPort(0, 0, width, height);
renderer.readFrameBuffer(out, outBuf);
renderer.setViewPort(viewX, viewY, viewWidth, viewHeight);

代码示例来源：origin: jMonkeyEngine/jmonkeyengine

private void setViewPort(Camera cam) {
    // this will make sure to update viewport only if needed
    if (cam != prevCam || cam.isViewportChanged()) {
      viewX      = (int) (cam.getViewPortLeft() * cam.getWidth());
      viewY      = (int) (cam.getViewPortBottom() * cam.getHeight());
      int viewX2 = (int) (cam.getViewPortRight() * cam.getWidth());
      int viewY2 = (int) (cam.getViewPortTop() * cam.getHeight());
      viewWidth  = viewX2 - viewX;
      viewHeight = viewY2 - viewY;
      uniformBindingManager.setViewPort(viewX, viewY, viewWidth, viewHeight);
      renderer.setViewPort(viewX, viewY, viewWidth, viewHeight);
      renderer.setClipRect(viewX, viewY, viewWidth, viewHeight);
      cam.clearViewportChanged();
      prevCam = cam;

//            float translateX = viewWidth == viewX ? 0 : -(viewWidth + viewX) / (viewWidth - viewX);
//            float translateY = viewHeight == viewY ? 0 : -(viewHeight + viewY) / (viewHeight - viewY);
//            float scaleX = viewWidth == viewX ? 1f : 2f / (viewWidth - viewX);
//            float scaleY = viewHeight == viewY ? 1f : 2f / (viewHeight - viewY);
//            
//            orthoMatrix.loadIdentity();
//            orthoMatrix.setTranslation(translateX, translateY, 0);
//            orthoMatrix.setScale(scaleX, scaleY, 0); 

      orthoMatrix.loadIdentity();
      orthoMatrix.setTranslation(-1f, -1f, 0f);
      orthoMatrix.setScale(2f / cam.getWidth(), 2f / cam.getHeight(), 0f);
    }
  }
