Description:
A displacement shader providing a knurled pattern similar to grips used on tool handles. With default scaling, each unit square in texture space contains a pyrimidal displacement. A blend is applied to the edges of the pyramid with the size defined by parameter "Blend". This value should lie in the range 0.0 to 1.0, where 0.0 denotes no blend (the displacements correspond to pyramids) and 1.0 denotes maximum blend (the displacements correspond to cones).

Two scaling factors may be applied. The "Amplitude" parameter applies a scale to the height of the displacements. A value between 0.0 and 1.0 will flatten the indentations, and values greater than 1 will accentuate the relative differences in height over the indentation. Values less than 0.0 will reverse the direction of the indentations. An overall scaling factor can be specified by argument "Scale"; increasing this value will make the indentation pattern appear larger.

  • Scale - Overall scaling factor; increasing this value will make the pattern appear larger.
  • Blend - Applies a blend to the edges of the indentations where they meet the flat surrounding surface. This value should lie in the range 0.0 to 1.0, where 0.0 denotes no blend (the displacements correspond to pyramids) and 1.0 denotes maximum blend (the displacements correspond to cones).
  • Amplitude - Scales the height of the displacements. A value between 0.0 and 1.0 will flatten the indentations, and values greater than 1 will accentuate the relative differences in height over the indentation. Values less than 0.0 will reverse the direction of the indentations.

Search Help

Default search behavior

By default, all search terms are optional.Objects that contain the terms are rated higher in the results. For example, wiki forum will find:

  • objects that include the term wiki
  • objects that include the term forum
  • objects that include both terms

Requiring terms

Add a plus sign ( + ) before a term to indicate that the term must appear in results.

Excluding terms

Add a minus sign ( - ) before a term to indicate that the term must not appear results.To reduce a term's value without completely excluding it, use a tilde.

Grouping terms

Use parenthesis ( ) to group terms into subexpressions.

Finding phrases

Use double quotes ( " ) around a phrase to find terms in the exact order, exactly as typed.

Using wildcards

Add an asterisk ( * ) after a term to find objects that include the root word. For example, run* will find:

  • objects that include the term run
  • objects that include the term runner
  • objects that include the term running

Reducing a term's value

Add a tilde ( ~ ) before a term to reduce its value indicate to the ranking of the results.Objects that contain the term will appear lower than other objects (unlike the minus signwhich will completely exclude a term).

Changing relevance value

Add a less than ( < ) or greater than ( > ) sign before a term to change the term's contribution to the overall relevance value assigned to a row.
