Supersampling Factor

When you render a scene in Indigo, you may sometimes encounter the issues of blurry edges, especially the seam lines between faces with extremely contrasted colors, or white highlight pixels scattered around the images, to combat this you may use the Supersampling Factor feature.

Supersampling Concepts

The supersampling technique is to render a scene by multiplying the target resolution with a given factor value before the rendering result is displayed on the working area in the target resolution. It is to eliminate the issues described above by trading off with slower speed and more system memory.

  1. Indigo multiplies the target rendering resolution (the image that is highlighted in blue) with a given supersampling factor behind the scene.
  2. It starts to render the scene pixel by pixel in the multiplied resolution.
  3. Afterward, the rendered result will be resized down to fit into the target rendering resolution and displayed on-screen.

    Note:

    By doing so, the pixels that are yet to be rendered in the behind-the-scene image with larger resolution at Step B will be less obvious, eliminated, or even removed as soon as the image is resized down and displayed in the working area.

Using Supersampling for Better Rendering Results

In order to obtain a better rendering result, you may assign a certain supersampling factor described above, to Indigo.

  1. Prepare an iClone project.
  2. In the iClone Indigo Render Plug-in setting panel, move to the bottom page.

    Note:

    The size of the light is resized in this example.

  3. Set the Supersampling Factor to 1.

    Note:

    The value, by default, is 2.

  4. Export the project to Indigo for rendering.
    • This illustration is the rendered result after 1 minute.
    • There are some obvious grainy and scattered highlighting pixels left without rendering.
  5. Go back to the iClone Indigo Render Plug-in setting panel, set the Supersampling Factor to 5.
  6. Render the scene again in Indigo.
    • This illustration is the rendered result after 1 minute.
    • The artifacts are eliminated by the supersampling method.
