The Texture to Geometry options are divided into four categories based on their related function. Some of these options are also available from the Attribute Editor. This lets you modify the parameters after the initial surface mesh is created and update the resulting mesh through the construction history connection. Input Image Specifies the image you want to convert into geometry. Type the directory path and file name in this text box. Because it is possible to have multiple textures assigned to a surface, you must specify which image you want converted in the Input Image text box. Segment Detection Options These options specify how color features in the input image are detected and then subsequently converted into segments that define the areas for subdivision of the resulting mesh. Quantize Images that contain subtle color changes (color ramps or blends) can be problematic for the detection and segmentation phase of the Texture to Geometry feature. Turning this option on helps the feature determine segments in images that contain gradient color changes. For example, if the image contained a gradient (ramp) background, the gradient region would be divided into equal segments based on the Quantize Level option settings. Turn this option on only if your image contains gradient color changes. Quantize Levels Quantize Levels uses the color value information in HSV color space to set the number of color levels in the image when the Quantize option is turned on. The level setting affects how the gradient color regions get divided during the detection and segmentation phase. For example, a Quantize Level of 16 indicates that the detection/segmentation of the image would be divided into 16 areas based on the Value parameter in HSV color space for the pixels in the gradient region. This option is only available when the Quantize option is turned on and is specifically useful for images that contain gradient color changes. Search Radius Texture to Geometry uses a search algorithm that looks at neighboring pixels in the image to determine which segment of the image matches a given pixel. Search Radius determines the size of the searching radius in pixels. The valid range for this option is between 3 and 10. The default Search Radius is 7 pixels. The smaller you set the Search Radius value, the less likely the search algorithm will find a segment and the more segments will get produced as a result. Basics 285
