● Increment for Clones:

This setting is more or less for the same purpose as the Texture array but it is not

necessary to have different image files for this to work. If the object you want to apply the

material on has several clones, you can apply different materials to each clone by

checking this option and creating the materials next to each other. The first clone will get

the first material (the one you assign), the second will get the next material, etc.

● Culling

This parameter determines to a great extent which parts of a given object will be drawn.

The polygons of a solid object which face back, away from the camera, are usually not

shown, so it is unnecessary to draw them. They are discarded – hence the word 'culling'.

In real time 3D rendering it is a significant feature, because the graphic card may need all

the speed optimization it can get.

In the case of less than fully opaque objects or in other, special cases it may become

necessary to avoid the general rule and to determine which polygons should be drawn

and which can be culled. Possible settings are:

Back Face: Default setting. Polygons facing backwards are culled.

Front Face: the case is the reverse, polygons facing front are culled.

Back and Front: polygons facing front and back are culled.

None: All polygons are to be drawn.

● Draw:

OpenGI can draw the objects not only with shaded polygons. The possible settings are:

Polygons: default

Smoothed Lines: Only the edges of the polygons are drawn as lines. The inside of the

polygons remain empty.

Stippled Lines. It also draws only the edges but with stippled line patterns set in the

Stipple parameter.

Points: It draws only the vertices as points but neither the edges nor the inside of the

polygons.

● Size:

It defines either the width of the line or the size of the point depending on whether lines or

points are to be drawn according to the value of the Draw parameter. The maximum line

width is 10 but the point size can be bigger (the maximum value depends on your GPU).

● Stipple:

If you choose stippled lines as the setting for the Draw property, you can define the

pattern of the line with this property.
