Mastering the art of blending images seamlessly for a captivating cross-fading effect

I'm attempting to create an image cross fade effect using the following steps:

Place the selected image in the front (position: -9999 to 0)
Position the previous image in the back (position: 0 to -9999)
Gradually increase the opacity of the selected image until it reaches 1
Set the opacity of the previous image to 0 (to repeat the process)

Here is the code snippet:

  <a-sky id="pano-1" src="image1" class="pano" opacity="0" position="-9999"></a-sky>
  <a-sky id="pano-2" src="image2" class="pano" opacity="0" position="-9999"></a-sky>

  var opacity = 0; // initial opacity
  var step = 0.1; // step size
  var target = 1; // target value
  var time = 50; // delay in milliseconds

  var increaseOpacity = setInterval(function () {
    opacity = (opacity * 10 + step * 10) / 10;
    if (opacity > target) {
      clearInterval(increaseOpacity);
    }

  }, time);

  $('#pano-${index}').attr('position', 0);
  $('.pano').not('#pano-${index}').attr('position', -9999);
  $('.pano').not('#pano-${index}').attr('opacity', 0);

The images are fading in and out, but not crossing each other (going from the old image to a white screen before the new image appears).

Is the order incorrect? How can I achieve the effect of the images seamlessly crossing over each other?

Answer №1

It appears that you are rearranging the other elements before the fade effect is fully completed. To address this, you can adjust the positioning of the elements as follows:

  var opacity = 0; // initial opacity
  var step = 0.1; // step size
  var target = 1; // target opacity value
  var time = 50; // delay in milliseconds

  var increaseOpacity = setInterval(function () {
    // Set the opacity based on the step size
    opacity = Math.round((opacity + step) * 10) / 10;
    // Check if target opacity is reached and stop the timer
    if (opacity >= target) {
      clearInterval(increaseOpacity);
      $('.pano').not(`#pano-${index}`).attr('position', -9999);
      $('.pano').not(`#pano-${index}`).attr('opacity', 0);
    }
  }, time);

  $(`#pano-${index}`).attr('position', 0);

Another potential issue you may encounter is related to the z-index, but I recommend trying the above solution first.

In my opinion, it is crucial to maintain simplicity in tasks like this. It is advisable to rely on CSS whenever possible and reserve the use of Javascript for handling business logic only.

function SliderCtrl($) {
  var self = this;
  
  self.slider = $('#slider');
  self.imgs = $('img', self.slider);
  self.current = null;
  self.ACTIVE_CLASS = 'is-active';
  self.TIMING = 2000;
  
  self.changeSlide = function() {
    var current = $(self.current);
    var next = current.next().length ? current.next() : self.imgs.first();
    console.log(next, current)
    
        
    current.removeClass(self.ACTIVE_CLASS);
    next.addClass(self.ACTIVE_CLASS);
    self.current = next;
  };
  
  window.setInterval(self.changeSlide, self.TIMING);
  self.slider.removeClass('is-waiting');
}
$(document).ready(SliderCtrl);

#slider {
