By applying images or gradients to the inside of a giant sphere, Horizon creates an infinite background. No matter where your camera is directed, the simple controls make photorealistic backgrounds or sky gradients a snap.
Features of Trapcode Horizon:
Floating Point Support
Offers support for Floating point mapping of .exr image maps in After Effects CS3
Equirectilinear Image Mapping
Familiar to 3D artists, “equirectilinear” images are maps that provide full 360-degree coverage of a sphere. Horizon will map these images seamlessly onto the background.
Built-in gradient modes provide up to 8 colors for generating colors on the virtual sphere.
With controls for horizontal and vertical coverage of the sphere, you can determine how much of the virtual sphere to map—especially useful for using non-panoramic images or video.
Mapping in Horizon depends on the Field of View in After Effects, so you can create a zoom effect by animating the field of view of the After Effects camera.
Trapcode Horizon runs only in Adobe After Effects CS3, 7.
