is described by its radius). To see how many
polygons are in the scene, turn off this box to
export 3ds Max primitives, which have an indexed
face set for each object. Default=on.
Flip-B ook—Exportsthescenetomultiplefiles.The
sample rate is set in the in the F lip-B ook section
of the Sample Rates dialog. The file name you
specify becomes the base for the sequence of files.
For example, if you specify the file name test.wrl,
choose one fi le per animation frame, and have five
frames, 3ds Max exports the following:
test.txt contains general info, start/stop times, and
number of fra mes.
test0.wrl through test4.wrl are snapshots of the
animation in f rames 0 through 4.
Co lor Per V ertex—Exports the vertex colors of
geometry.Ifthisisturnedon,theColorPerVertex
Source lets you choose the source of the vertex
color.
Polygons Type
Determines how geometric faces are written out as
VRML97 IndexedFaceSet nodes.
Ngons—Writesfaceswithasmanyedgesas
possible.
Quads—Writes quadrilateral faces where possible
(other wise tr iangles).
Triangles—Writes only triangular faces.
Visible Edges—Breaks faces at internal edges that
are marked as being visible.
Initial V iew
Sets the entry camera for t he scene and controls
what first appears in the browser. If there are no
cameras in the scene, the scene appears with a
default viewpoint (which may give only a partial
view).
Allscenesshouldhaveatleastonecamera,so
yo u can control how the scene initially renders.
Add more cameras to the scene than you mig ht
ordinarily use, so the viewer can switch between
cameras if his VRML97 browser allows it. This
lets you set up your scene with pre-installed
vantage points. Otherwise, if the world is very
large, it can overpower the v iewer’s s ystem and
make navigation difficult. Some browsers animate
camera move s, so the extr a cam era s can make
viewingthescenemorepleasant.
Initial Navigation Info
Specifies the Navigation Info helper object (page
3–599) to use when the world loads in the browser.
Initial Background
Specifies the Background helper object (page
3–605) to use when the world loads in the browser.
Initial Fog
Specifies the Fog helper object (page 3–600) to use
when the world loads in the browser.
Digits of Precision
Sets the number of decimal points used for
calculating dimensions. The default of 4 is usually
sufficient. Set this number greater than 4 if parts
of your world were created 100,000 units away
from the center of the scene. Sett ing the value to 3
reduces the file size.
Show Progress Bar
Gives you the option to view a progress bar as the
scene is exported.
Vertex Color Source group
Lets you choose the source for the vertex color
when Color Per Vertex is turned on.
