Change camera view for RENDERBUFFER but not for main render view

21 views Asked by At

I got nice working RENDERBUFFER buffer using example but i cant change camera view only for framebuffer render view.

I wanna make second camera with own camera params...

Creating framebuffer:

function makeFbo() {
//////////////////////////////////////////////////////
  // TEST 2 Success for now just fbo
  // gl.getParameter(gl.MAX_DRAW_BUFFERS)
  //////////////////////////////////////////////////////
  var framebuffer, texture, depthBuffer;
  console.log('FBO MAKE FUNC !!!');

  var error = function() {
    console.log('Error in creating FBO!');
    return null;
  }

  framebuffer = gl.createFramebuffer();
  if(!framebuffer) {
    console.log('Failed to create frame buffer object');
    return error();
  }

  texture = gl.createTexture();
  if(!texture) {
    console.log('Failed to create texture object');
    return error();
  }

  // local
  var OFFSCREEN_WIDTH = 512;
  var OFFSCREEN_HEIGHT = 512;

  gl.bindTexture(gl.TEXTURE_2D, texture);
  gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, OFFSCREEN_WIDTH, OFFSCREEN_HEIGHT, 0, gl.RGBA, gl.UNSIGNED_BYTE, null);
  gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MIN_FILTER, gl.LINEAR);
  framebuffer.texture = texture;

  depthBuffer = gl.createRenderbuffer();
  if(!depthBuffer) {
    console.log('Failed to create renderbuffer object');
    return error();
  }
  gl.bindRenderbuffer(gl.RENDERBUFFER, depthBuffer);
  gl.renderbufferStorage(gl.RENDERBUFFER, gl.DEPTH_COMPONENT16, OFFSCREEN_WIDTH, OFFSCREEN_HEIGHT);

  // Attach the texture and the renderbuffer object to the FBO
  gl.bindFramebuffer(gl.FRAMEBUFFER, framebuffer);
  gl.framebufferTexture2D(gl.FRAMEBUFFER, gl.COLOR_ATTACHMENT0, gl.TEXTURE_2D, texture, 0);
  gl.framebufferRenderbuffer(gl.FRAMEBUFFER, gl.DEPTH_ATTACHMENT, gl.RENDERBUFFER, depthBuffer);

  // Check if FBO is configured correctly
  var e = gl.checkFramebufferStatus(gl.FRAMEBUFFER);
  if(gl.FRAMEBUFFER_COMPLETE !== e) {
    console.log('Frame buffer object is incomplete: ' + e.toString());
    return error();
  }

  // Unbind the buffer object
  gl.bindFramebuffer(gl.FRAMEBUFFER, null);
  gl.bindTexture(gl.TEXTURE_2D, null);
  gl.bindRenderbuffer(gl.RENDERBUFFER, null);

  return framebuffer;
}

Render func:

App.operation.reDrawGlobal = function(time) {
  modifyLooper(0);
  if(App.offScreenCanvas == false) reDrawID = requestAnimationFrame(App.operation.reDrawGlobal);
  world.renderPerspective();

  for(var t = 0;t < App.updateBeforeDraw.length;t++) {
    App.updateBeforeDraw[t].UPDATE();
  }


  // ....

  // - non FBO and FBO option draw coroutine

    }

    document.getElementById('globalAnimCounter').innerText = world.globalAnimCounter;
    document.getElementById('timeline').value = world.globalAnimCounter;
  }


};

Here is example what i want. This is scene with +3 camera view with different view.

Maybe i need to setup for every framebuffer special draw then then redraw all. I have feeling i will stack with blinking screen...

Any suggestion ?

I get framebuffer view only camera manipulate option when i put camera manipulation code before calling bindFramebuffer !

  • // reset camera come before redraw all !
App.operation.reDrawGlobal = function(time) {
  modifyLooper(0);
  if(App.offScreenCanvas == false) reDrawID = requestAnimationFrame(App.operation.reDrawGlobal);
  world.renderPerspective();

  for(var t = 0;t < App.updateBeforeDraw.length;t++) {
    App.updateBeforeDraw[t].UPDATE();
  }
