Collect

Collect combines geometric primitive objects like points, lines, polygons, triangle strips with colors, normals and textures

Collect is available for all COVISE versions on all platforms.

Input Ports

Name	Type	Description
requiredgrid	StructuredGrid UnstructuredGrid RectilinearGrid UniformGrid Points Lines Polygons	The computational grid of any type.
optionalcolors	Structured_V3D_Colors Unstructured_V3D_Colors RGBA_Colors Float Float	Optional input port: colors at the vertices of the grid.
optionalnormals	Structured_V3D_Normals Unstructured_V3D_Normals	Optional input port: normals at the vertices of the grid.
optionaltextures	Textures	Optional input port: textures.

Output Ports

Name	Type	Description
outputgeometry	Geometry	The combined object.

Example 1

In tutorial_pressure_1.net (first map)the left RWCovise module reads in the computational grid of a channel with two inlets. The second RWCovise module reads in the pressure distribution. The module CuttingSurface cuts the 3D data with a plane and computes the pressure values on the plane. The plane ia a list of polygons or trianglestrips. Collect combines the polygons/trianglestrips and the colors into a geometry object for the renderer.

Example 2

In tutorial_pressure_2.net (second map) the RWCovise modules again read in the computational grid and the pressure data on the grid. IsoSurface computes an isosurface (a surface connecting all points with a certain pressure value).IsoSurface also computes the surface normals. Collect combines the polygons/tristripes of the isosurface, the colors on the surface and the normals into a geometry object.

Example 3

In the third map, the RWCovise modules again read the grid and the pressure data. DomainSurface computes the outer surface of the grid as polygons and the data on the outer surface. Colors maps the pressure data to colors as a texture. Collect combines the texture and the polygons into a geometry object.
