2D Layer

2D Layer  -  A single 2D Layer

This topic describes the different types of 2D layers in Smode.

Basically, 2D Layers are used to generate an image, modify it and then render it. Here are the involved elements to perform this:

• 2D Generator :
  The generator represents a source of images. Many different types of generator exist:
  still images, videos, live video feeds, shaders generating an image in real-time…
• 2D Modifier :
  A 2D layer contains a chain of modifiers that are applied to the image of the Generator.
  A wide number of 2D modifiers are provided ranging from simple colorimetry operations to advanced stylization effects.
• 2D Mask :
  Any 2D modifier in Smode can be modulated with 2D masks that define for every pixel the level
  of application of this modifier. Masks enable numerous applications from traditional transparency-masking
  to advanced modulation of stylisation and distortion effects.
• 2D Renderer :
  Once the image is modified, it gets rendered by its 2D Renderer .
  By default there is one such renderer, but it’s very easy to turn it into a Group 2D Renderer to get
  the layer displayed multiple times (without nearly any additional cost).
  Each renderer has an opacity and a blending mode and it is possible to add local 2D Modifier on renderers.

The following picture illustrates how the different components constituting a 2D layer operate together:

Note: To group multiple objects together, select them and press [CTRL] + [SHIFT] + [G]. This will have different
effects if you choose 2D Renderer , 2D Modifier or 2D Layer .

Note: A group of 2D Layer is not rasterized and has no specific resolution.
If you want to create a Compo while grouping them, use the [CTRL] + [SHIFT] + [C] shortcut.

Here is a little composition made from a lot of 2D layers (images, videos, sprite-sheets) that runs on Smode in real time:
