Grid SOP
Summary[edit]
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 - Page
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
poly-
- Mesh
mesh-
- NURBS
nurbs-
- Bezier
bezier-
Connectivity surftype - ⊞ - (Results only viewable for polygons and meshes).
- Rows
rows- Creates horizontal lines.
- Columns
cols- Creates vertical lines.
- Rows and Columns
rowcol- 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
triangles- Build the grid with Triangles.
- Quadrilaterals
quads- Generates sides composed of quadrilaterals (default).
- Alternating Triangles
alttriangles- Generates triangles that are opposed; similar to the Triangles option.
Orientation orient - ⊞ - Specifies on which plane the Grid is built.
- XY Plane
xy-
- YZ Plane
yz-
- ZX Plane
zx-
Modify Bounds modifybounds - Enabled only when an input is connected to the Grid SOP to set bounds for the grid. Turn Modify Bounds = On to enable the transform parameters below to further modify the position and scale of the bounds.
Size size - ⊞ - The X and Y scale of the grid.
- X
sizex-
- Y
sizey-
Center t - ⊞ - Center of grid in X, Y, and Z.
- X
tx-
- Y
ty-
- Z
tz-
Rows rows - 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.
Columns 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.
U Order orderu - U Order Degree of spline basis +1 in the U parametric direction.
V Order orderv - V Order Degree of spline basis +1 in the V parametric direction.
End Point Interpolate in U interpu - End-point interpolate in U Extends the surface to touch the end point in the U direction.
End Point Interpolate in V interpv - 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 Grid SOP.
- Off
off- No uv coordinates added.
- Row & Columns
rowcol- uv coordinates added based on Rows and Columns in the geometry.
Compute Normals normals - Checking this option On will compute surface normals.
