On the Display tab of the
property sheet that is associated with a data object in ParaView you will
find a Display style region similar to the one shown in the image on the
right. In this area you can change the representation of the data, the
interpolation method, and the size of points and lines as described below.
Representation: You can choose between a surface, a wireframe or a point representation of the data. When a surface representation is selected, primitives such as polygons and triangles are drawn as filled geometric primitives. When wireframe mode is selected, only the edges are drawn. In point mode, only the points defining the geometry are displayed.
Interpolation: In Gouraud interpolation the normal will be interpolated over the face of a polygon for shading. When flat shading is selected only one normal will be used per polygon leading to a more faceted appearance. Objects that do not have point normals will be drawn with flat shading regardless of the setting of the pulldown.
Point size: When displaying points either as part of the data object or due to a Representation of points, the point size can be controlled with this slider.
Line width: If lines are being drawn for the data object (either because lines are a part of the data object or because the representation has been set to wireframe) then this slider can be used to control the thickness of the lines.
