13.16.  Sphere Designer

13.16.1.  Overview

Figure 11.221.  The same image, before and after the application of “Sphere Designer” filter.

This filter creates a three dimentional sphere with different textures. It replaces the original image.

13.16.2.  Activating Sphere Designer

This filter is found in Filters->Render->Sphere Designer.

Preview

All your setting changes will appear in the Preview without affecting the image until you click on OK. Note that the preview displays the whole image, even if the final result will concern a selection. Click the button Update Preview to see the result of the current settings.

Textures

Textures: The list of textures applied to the sphere. There textures are applied in the order listed. Each item shows the type and the name of the texture.

Add

Add: Creates a new texture and adds it to the end of the list.

Copy

Copy: Copies the selected texture and adds the copy to the end of the list.

Delete

Delete: Deletes the selected texture from the list.

Open/Save

Open/Save: Allows to save current settings or load previously saved settings.

Texture properties
Type

Type: Determines the type of influence on the sphere. Texture covers the sphere with a specific pattern. Bumpmap creates a bump map, but does not affect the image. Light allows to set the parameters of the light shinig on the sphere.

Texture

Texture: Determines the pattern used by the texture type. If the texture applies to light then the light is distorted by this texture as if goes through this texture before falling onto the sphere. If the texture applies to the texture itself, the texture is applied directly to the sphere. The following options are available: “Solid”, “Checker”, “Marble”, “Lizard”, “Phong”, “Noise”, “Wood”, “Spiral” and “Spots”.

Colors

Colors: Sets the two colors to be used for a texture. By pressing the color button a color selection dialog appears.

Scale

Scale: Determines the size of separate elements comprising the texture. For example, for the “Checker” texture this parameters determines the size of black and white squares. Value range is from 0 to 10.

Turbulence

Turbulence: Determines the degree of texture distortion before applying the texture to the sphere. Value range is from 0 to 10. With values of up to 1.0 you can still make out the undistorted patterns; beyond that the texture gradually turns into noise.

Amount

Amount: Determines the degree of influence the texture has on the final result. Value range is from 0 to 1. With the value of 0 the texture does not affect the result.

Exponent

Exponent: TODO purpose unknown.

Texture Transformations
Scale X/Y/Z

Scale X/Y/Z: Determines the degree of streching/compression of the texture on the sphere along the three directions. The value range is from 0 to 10.

Rotate X/Y/Z

Rotate X/Y/Z: Determines the amount of a turn of the texture on the sphere around the three axes. The value range is from 0 to 360.

Position X/Y/Z

Position X/Y/Z: Determines the position of the texture relative to the sphere. Applies only (TODO is it?) to light.

Reset

Reset: Sets all parameters to the default values.
