lighting and shading in prman

Lightsource “spotlight”

name of data followed by value of data.

Lightsource “spotlight” 1 “intensity” 50

maya intensity can be up to 1
in prman it can go higher

Lightsource “spotlight” 1 “intensity” 50

lights

broadly speaking ther are two types of lights

directional lights
distant light-the illumination is indepentedt of position
they have no fixed position in space.

-positional light
these generally havea drop off , transparentcy.

these have definant XYZ location.
inverse square law .

the tif

then tex file conversion .

tools show tools . show texture tool

creates a drop own list .
fing the rman folder .
then the tif file .
identfy the iff then add

on “s” and “t” option chose black black

__make texture_______
then there wil be warnings .
becuse the rendere dosn’t under stand a few items . but it’s ok.

at this point it will have created a texture in te texture folder.

the tx file is 4x’s bigger then the tiff
this creates a stabe map.

mip map.
a map useing multiple maps to render depending on the distane .

helps prevent texture boiling.
mayas renderer can boil

_

gave us 2 source codes for shaders.\
open 2 text files . them click shader in rman tools.
( the combo has source warnings . but warnings are “ok”)

that has compiled the shader.
close them .

we are useing combo.

now change plastic to combo

_____________
Surface “combo” “texname”
__________________
Surface “combo” “texname” ["texture.tx"]
_______________
next pointing to the texture.

full path to combo

Surface “H:/rman/shaders/combo” “texname” ["H:/rman/textures/texture.tx"]

____________________________

the s and the t

photoshop image

covered a certain # of pixals .

for the purpose of texture mapping the renderer ignores the acctual pixals . and in stead thinks of the image from the orign .

S is the origan “x”

T is how far away from s “y”

binding

then change 1 to 3 for a tile
then change to periodic s and t

check over writte text ure . and then remake texture

____________________

centering the five .

not perfect but thats the idea.

negative is
upside down an backwardes

rotating the binding

You Know You’re Addicted to Photoshop When…

You see the world with one eye and stock images with the other. When asked what the primary colors are, answer “RGB” You get the urge to ‘fix’ poor quality images. You start teaching your significant other to use this “evil” program and in the space of one afternoon convince them it’s at least only quasi-evil in the face of PSP. You ramble about a breakthrough in the piece you’re doing to people who have no idea in hell what you’re talking about You ponder the meaning of existence without layers. You never leave the house without a digicam and notepad. You drop something and your brain tells you automatically “Ctrl-Z! Ctrl-Z!”. When you realize it won’t work, your brain tells you “Ctrl-Alt-Z! Ctrl-Alt-Z!” You’re getting dressed for something important and you look in the mirror and realize you would look so much better if you could just tweak the levels a little and apply a slight gaussian blur. You stop on the street to rant about cheesey effects that should not be on professional posters. You scream out fonts as they appear on TV. You have dreams in “glowing edges” You’re standing by the ocean and wondering who used Ocean Ripple. You actually get these jokes and pass them on to other friends who are addicted to Photoshop.
