Grid SOP

Summary

The Grid SOP allows you to create grids and rectangles using polygons, a mesh, Bzier and NURBS surfaces, or multiple lines using open polygons.

Parameters

Primitive Type /type - Select from the following types. For information on the different types, see the Geometry Types section. Depending on the primitive type chosen, some SOP options may not apply.

• Polygon -
• Mesh -
• NURBS Surface -
• Bzier Surface -

Connectivity /surftype - (Results only viewable for polygons and meshes).

• Rows - Creates horizontal lines.
• Columns - Creates vertical lines.
• Rows & Cols - Both Rows and Columns. Looks like Quads in wireframe display, but all polygons are open (if the primitive type is polygon). Compare them in the Model Editor.
• Triangles - Build the grid with Triangles.
• Quadrilaterals - Generates sides composed of quadrilaterals (default).
• Alternating Triangles - Generates triangles that are opposed; similar to the Triangles option.

Orientation Plane /orient - Specifies on which plane the Grid is built.

Size /sizex /sizey - The X and Y scale of the grid.

Center /t - Center of grid in X, Y, and Z.

Rows & Cols /rows /cols - The number of rows and columns. Rows are horizontal lines; Columns are vertical lines. Two rows by two columns makes a square or rectangle. For example, one row and two columns makes a single line if Connectivity is set to Rows.

For NURBS and Bzier surfaces, the Rows & Cols refer to the surface hull construction, and as such, the number of Rows and Cols should not be less than the Order in U or V.

Order /orderu /orderv

• U Order Degree of spline basis +1 in the U parametric direction.
• V Order Degree of spline basis +1 in the V parametric direction.

Interpolation /interpu /interpv - These options are used for higher-order (i.e. NURBS, Bzier) surfaces.

• End-point interpolate in U Extends the surface to touch the end point in the U direction.
• End-point interpolate in V Extends the surface to touch the end point in the V direction.

Texture Coordinates /texture - This adds uv coordinates to the geometry created by the Font SOP.

• Off - no uv coordinates added
• Rows and Columns - uv coordinates added based on Rows and Columns in the geometry.
