In the Background tab are
present the background controls. Clicking on the Background color
box, you can change the background color. As an example, this
function is very useful to change the background from black to white
in order to print the scene. Changing the Logo gadget, you
can activate the superimposition of the VEGA ZZ logo. It can be
placed at Top left, Top center, Top right, Center
left, Centered, Center right, Bottom left, Bottom
center and Bottom right.
If the background color change isn't enough for you, you could use the SkyVision
system that applies a 3D landscape to the scene. More in details, it
places the scene inside a cube (skybox) with texturized faces and
is the same method used in modern 3D video game to render the landscape.
By this way, it's clear that six texture files are required for each
landscape. They must be placed in the SkyBoxes directory and must
be in JPEG format. The resolution of the image could be 128x128, 256x256
and 512x512 pixels. Larger images aren't recommended because they requires
a lot of graphic memory and go down the rendering performances. The six
files must have a specific name. If the skybox name is landscape,
the file defining the six faces must be: landscape_back.jpg,
landscape_bottom.jpg, landscape_front.jpg, landscape_left.jpg,
landscape_right.jpg and landscape_top.jpg. The landscape can be adjusted
in the scene changing the position (X offset and Y offset)
and the orientation (X rotation, Y rotation and Z
rotation). When you click the dot buttons, the parameter is reset to
default.
