anistrophic fileter-makes texture sharpened. ex. in perspective angle

TEXTURE-max anisopft

pbuffer capture-high res screenshot-press f1. depends on how much memory is on graphic card

take screenshot of rectangle fragments of opengl art and put them together in photoshop

frustum pyramid- pyramid w/ top cut off

gl lookat

google as extension of memory.

McClune-media as extension. media extend human nervous system. google is perfect example of media expanding human nervous system.

google measures response time for humans and manages to make results page come up faster.

non-technology artist getting awkward while getting used to media art. takes long time for them to get used technology art environment. traditionalist art and technology art are very different. two different worlds.

motions painted in art-francis bacon, marshall duchamp. movement not perceived by humans.

wikipedia-structure of knowledge. still has impact on human nervous system.

post final idea to wiki.

draw 2 models within exact spot.

processing jar in the folder in GLArt folder. tell program where jar is. function to get processing.

put guy’s image on big black paper on wall. guy’s image turns into terminator as his flesh strips away as person gets closer.

openFrameworks-for visual artists

grab image from web and put it into quartz composer and use texture and can make it flip around

flash is for heavy visuals for web but for others markup language work better

eclipse is all java

iphone-supports opengl

python is slower

use IR sensor in processing and bring processing jar into eclipse

text

can write text on the screen

GL tutorial for things advanced-link on 1st page

IR sensor for final. dropping triangle by triangle. max/jitter?

tim-billboarding

tom-text imported from websites

tv-low resolution w/ lots of noisy big pixels. requires audience to participate more than in movie theaters

medium is extension of man. aplifies or accelerates human capability.

try putting text into my project.

array of triangles. number each triangle.

math.random()*100f

gluProject-recreates new geometry and perspective

gluUnProject

getViewport

glModelviewMatrix

projectVerts

earth

texture image dimentsions must be power of 2

how image will be mapped onto vertices

texture coordinate points-U,V

GLTEXCOORD(U,V)

256 -right resolution for texture

make mesh first, flatten it out, map texture on them

texture may stretch

get texture image loaded up

if not able to read texture image, try JAR file

OpenGL-RGBA, Java-ARGB(have to be changed to OpenGL format)

makeTextureMipMap-how detailed texture should be. preprocess and blend before mapping them on.

smoother.

OpenGL doesn’t load up images. it gets pixels from OpenGL class.

light changes by color of shapes

types of light color

• diffuse-1,0,0 RGB
• ambient-1,0,0
• specular-.8,.8,.8

GL_CULL_FACE-chop out area not needed

FloatBuffer-just a datatype

material has same values as light-diffuse,ambient,specular

specualr-amount of light reflected back

emission-surface is glowing

shininess-1-128, not a color

FloatBuffer-data. buffer fillled w/ numbers

glPerspective

Projection matrix-wide or narrow view. projecting on wall

glEnable(GL11.GL_DEPTH_TEST)//turns on depth test

COLOR BUFFER

FLOAT DEPTH[ ]

DEPTH BUFFER-what is closest thing to eye 0-1

Frustum structure view

ORTHO straight view

glViewport-deals w/ screen. don’t need to specify matrix

make 2 scenes-shapes in ortho and frustrum perspective.

f-float

show work on monday night latest 10pm

vertical v sinc

display is updated 60 frames/sec

GLU-GL utility functions on top of OpenGL

GLUT-windowing

GL11.glTranslatef

GL11.glLoadIdentity//reset the proejction matrix

//define perspective

GLU.gluPerspective{

45.0f, //field of view

//eye position GLU.gluLookAt

x,y,z coordinates can change their perspective

func face()

begin

vertex

end

moving separate from drawing shapes

transfroming vectors

vector=[x,y,z]=point=vertex

map points to another position.

matrix x vector points

2d array-16numbers stored-matrix math

openGL-matrix math machine.

moves point around to change the perspective

GL_MODELVIEW-moves the model around camera

glClear-clears screen. keeps track of depths of object. what’s front and what’s back.

GL_COLOR_BUFFER_BIT

functions: glTranslate(), glScale(), glRotate()

glTranslatef(2f, 0f,0f)

glLoadIdentity

openGL-drawing program. rotates objects.

glRotatef(120,0,1,0)

GL11.glPushmatrix(); //copy matrix into new matrix to rotate just one element of object (rotate just one eye)

glPopMatrix()-goes back to original matrix

leaving points alone n just changing x,y,z positions

assingment-rotating cubes. isolate them in each rotation. order matters. always rotating around origin. take a shape from last week and rotate, scale many times.

rotation +=.01f;
