Eyeon:Manual/Fusion 6/SoftClip
From VFXPedia
[ Main Manual Page ]
The SoftClip tool is used to fade out geometry and particles that get close to the camera. This to help avoid the visible 'popping off' that affects many particle systems and 3D flythroughs. This tool is very similar to the Fog 3D tool, in that it is dependent on the geometries distance from the camera.
The SoftClip tool is usually placed just before the renderer to ensure that downstream adjustments to lighting and textures do not affect the result. It can be placed in any part of the 3d portion of the flow if the soft clipping effect is only required for a portion of the scene.
External Inputs
- SoftClip.SceneInput
- [ orange, required ] This input expects a 3D scene.
Controls
This checkbox can be used to enable or disable the tool.
Changes the linear gradient to a curve shaped one.
By default the softclipping is done based upon the perpendicular distance to a plane (parallel with the near plane) passing through the eye point. When the radial option is checked the radial distance to the eye point is used instead of the perpendicular distance. The problem with perpendicular distance softclipping is that when you move the camera about, as objects on the left or right side of the frustum move into the center they become less clipped even though they remain the same distance from the eye. Radial softclip fixes this. Sometimes radial softclipping is not desirable. For example if you apply softclip to an object that is close to the camera like an image plane the center of the image plane could be unclipped while the edges could be fully clipped because they are further from the eye point.
Normally the effect is only visible when the scene is viewed using a Camera tool. When enabled, the softclip becomes visible in the scene from all points of view.
Defines the range of the softclip. The objects will begin to fade in from an opacity of 0 at the Transparent Distance and are fully visible at the opaque distance. All units are expressed as distance from the camera along the z-axis.
