Billboard (Built-in Patch) in Renderer, Render

Billboard

This patch renders a quad positioned with 2 coordinates and which always faces the viewer.

Because of these specificities, Billboard also has several unique features:
- Both dimensions of the quad can be set directly, or only one (in which case the other is computed automatically to preserve the aspect ratio of the image), or none (in that case, dimensions are automatically set so that the image is displayed at its real size).
- It can align the rendered image to pixel boundaries for the sharpest possible rendering (at the expense of motion smoothness).
Also, like Sprite, the image is multiplied by the color set on the “Color” input and can be combined with a mask using the optional “Mask Image” input (the mask will be resized to match the image’s size).
- It can crop images to the visible area within the destination context if specified in the patch settings.
- It can render images resulting from Core Image filters directly to the destination context if specified in the patch settings.

Note that Billboard is not affected by the environment fog or lighting, and contrary to Sprite, it will not render anything if its “Image” input is not defined.
