Subject: Vertex Colours 2004-02-23 - By Thomas Williams

wow. baking radiousity renders to vertex colors sounds like a cool
technique. I suppose the advantage of doing it this way (rather than baking
a texture) is no texture to load, and thus lower file size.
The other benefit would be that you vould do what NC has done, and animate
the vertex colors and thus 'morph' lighting effects. eg, a room vould morph
from a daylight render to a sunset render to dark or what have you. That's a
pressty cool thing you can't easily do with textures. Well, come to think of
it you could using IL and blend from one image to the next.
Another cool trick you kight could do would be to fake radiousity in real
time. That is, as a red ball gets close to a gray wall, the vertex colors od
the wall on the verts near the ball could shift to red, simulating the
reflected color of the ball 'bleeding' onto the wall. I kind of suspect that
is something close to what NC is doing with his vertex color anim.

Subject: Re: [Dir3d-l] Vertex Colours
The game engine I work with at my day job uses vertex colours for all
lighting. We calculate the radiosity solution in Max, bake this into the
vertex colour chanel using the "Assing Vertex Colors" util, export, and
everything works fine. Mind you, this works fine on PS2 and X-Box, but I
can't see why a similar system can't be used for Director.

dunno anout radiousity (i'd like to see THAT done with vertex colors!)
but Noisecrime did an excellent demo with vertexColors
http://www.noisecrime.com/develop/techdemo/d85/lightmapping/vertexlighting5.
htm
i haven't tried, but I suspect that max will export vertex colors (it
makes them np).
one caveat, you loose the blend in your texture once you set your
colorList to anything other than [].
colorList = numColors.count. It's a set colors made available as
vertexColors to the MR.

Hi all,
I have seen many posts/requests about vertex colours in Dir3D, whats
the deal???
I pretty much thought that Dir3D couldn't display vertex colour data
at all until I came across the definition for newMesh:
member(whichCastmember).newMesh(name, numFaces, numVertices,
numNormals, numColors, numTextureCoordinates)
Where numColors:
numColors is the optional total number of colors used by all the
faces. A color may be shared
by more than one face. You can specify a color for each corner of each
face. Specify colors for
smooth color gradation effects. Enter 0 or omit this argument to get
default white color per
face corner.
Has anyone used vertex colours in Dir to display radiosity solutions
etc?? Is the problem with using vertex colours that the W3D exporter does
not export the colours?
Tnk,
GM
