[jME Tutorial 2-6] Rainbow color Shader in the jMonkeyEngine Video Lecture | jMonkeyEngine Shader Tutorial: A Complete Tutorial - Game Development

I now going to try to do is create a
rainbow color based on the vertex fidget
positions in object space so to create a
very own very qualified like three
little copious don't exposition go to
that its position equals in position two
in position is the mesh vertices and
don't leave the rest as it is um yeah
for about this during the ten seconds
between making the other tutorial but
what I should have done which I did
start doing and then for screw this as a
create a default color then I should
have said if colors defined set color to
be bet and then one at the end and just
said GL Fred color equals color toward
over so I polish it other than also that
really want to be defining this unless
colors defined as well and it defines
are like C syntax if you didn't know so
if the find color passing the uniform
and Munsell color then end definition ok
but now what I really wanted to do was
based on the vertex position the object
space I want to convert that to a color
so I dt from the variant qualifier and
it's call it the same thing I called the
one in the message shader the speakers
that we the same
vertex position good now we're going to
pass in the vertex position here then
the right exposition of X 3 so that fits
perfectly and if I supply a color i'll
use that color instead so if i don't
specify anything i'll get rainbow or do
specify hear that normal boring color ok
let's test that out talking yet so i
specify the color so i'm going to get
that boring color run again oh snap so
yeah so it doesn't matter where I
position this sphere it's going to have
the exact same colors because i'm using
the vertex position in object space not
in the world space so if i move this
like three to the left to right it's
still going to have the exact same color
fragments because the thing that was
Edison pretty sure of the same
a blue and my territories and a wife let
me just let me just confirm this yeah
but if I do this go back to SciTech
Schrader and instead of using imposition
will at times it by the world matrix to
multiply that by G underscore control
space and it's well they made of slashes
world lyrics
of the matrix hmm skeptical but
nonetheless i need to add this to the
world parameters and also up here so now
i should get a different one with
everyone lives whoa okay to not like
wherever i just did there oh yeah
i'm doing everything on the fly by the
way i'm multiplying effect 3 buyer looks
like where is that don't like know what
line so 915 the vitac shaded 115 ok so
two passing position to make it more
consistent run where the snow is after
the same doing this to me hold matrix
sunset exists probably doesn't exist the
tuning engine amore on the page its
large the pager summer and globally
influenced this one on matrix and I
wasn't lying
doesn't bother showing it to me in here
though we'll try
just screw you while do matrix the
is up for this still the same make you
more not like a dickhead
just where the book is ready
Oh
so why that worked but fitted aha rather
goodbye doc those I'd just transforming
the vertices to the wild space
I sensation attention cancer
so did that work precisely i'm going to
awesome
a little I
you
you
so different yes this is just such
a system sisters various business
lessons lessons lessons today Oh gots 2
times the major fire out of a
while I'm their father
