This group of controls helps shape the form and integrate it with other graphic elements. For example, Spherical Field can push particles away from an area where a logo is placed. There are two Sphere fields, and they process in order: Sphere 1 first, then Sphere 2. ![ssg1](https://help.maxon.net/rg/en-us/Content/Resources/Images/ssg1_trapcode-form.png) **Strength:** Defines the field's power. Strength is the directional displacement amount with which the sphere pushes particles around, making it an important control. When set to a positive value, Strength creates a field that pushes particles outward and away from the spherical form. When set to a negative value, Strength pulls particles toward the center. Negative attracts, positive repels. ![s_off](https://help.maxon.net/rg/en-us/Content/Resources/Images/S_off_trapcode-form.gif)\ ![s_pos](https://help.maxon.net/rg/en-us/Content/Resources/Images/S_pos_trapcode-form.gif)\ ![s_neg](https://help.maxon.net/rg/en-us/Content/Resources/Images/S_neg_trapcode-form.gif) *Strength at 0 (left), a positive value (center), and a negative value (right).* **Sphere Position:** Positions the center of the sphere in 3D space along the x, y, and z axes. **Radius:** Defines the size of the Spherical Field for the x, y, and z planes together. Higher values make a larger field. ![sphere-radius30-str30](https://help.maxon.net/rg/en-us/Content/Resources/Images/sphere-radius30-str30_trapcode-form.jpg)\ ![sphere-radius160-str30](https://help.maxon.net/rg/en-us/Content/Resources/Images/sphere-radius160-str30_trapcode-form.jpg)\ ![sphere-radius160-strneg30](https://help.maxon.net/rg/en-us/Content/Resources/Images/sphere-radius160-strneg30_trapcode-form.jpg) *Radius at 30, Strength at 30 (left); Radius at 160, Strength at 30 (center); and Radius at 160, Strength at -30 (right).* **Scale X/Y/Z:** Scales the diameter of the field on the x, y, or z plane. Higher values make the plane larger. By default, all Scale values are set to 100, which creates a sphere. By setting different values for Scale X, Scale Y, and Scale Z, you can push a spherical field into any kind of elliptical shape. ![sphere-scale100](https://help.maxon.net/rg/en-us/Content/Resources/Images/sphere-scale100_trapcode-form.jpg)\ ![sphere-scalenew](https://help.maxon.net/rg/en-us/Content/Resources/Images/sphere-scalenew_trapcode-form.jpg) *Scale X at 100, Scale Y at 100, Scale Z at 100 (left) and Scale X at 230, Scale Y at 200, Scale Z at 50 (right).* **X/Y/Z Rotation:** Rotates the elliptical shape in the x, y, and z directions. **Feather:** Defines the softness of the edges of the Spherical Field. This feathers the strength of how far the field gets pushed out (or in). Higher values make a softer field. **Visualize Field checkbox:** With this checkbox enabled, a visual representation of the field displays. The x plane is in red, y plane is in blue, and z plane is in green. This is turned off by default. ![sphere-visualize](https://help.maxon.net/rg/en-us/Content/Resources/Images/sphere-visualize_trapcode-form.jpg)
