Reviewing 2D textures - applying Perlin Noise

mountain 2d texture mapped on the specular color of a blinn


mountain 2d texture mapped on the color of a blinn



mountain 2d texture mapped on the bump map of a blinn


a noise texture mapped to the specular color attribute of a blinn material



file texture without noise




file texture with noise mapped to its grain attribute

Reviewing 2D textures - applying water

a 2d water texture is mapped on a blinn as bump map


-not particularly suited for realistic liquid, but creates cool waves on cloth-like surfaces (Larnier,p.76)

Reviewing 2D Textures - applying cloth

repeat UValot of times






Reviewing 2D Textures ( according to Lee Laniers book tutorials)

shading with use background

(creates the shadow - it is a plane that responds to shadows but looks as the image plane connected to the camera

shading with a surface shader

has no shadow properties and doesnt take into account lighting information

shading with a shading map

where the colour of the blinn is normally dark, the bottom of the ramp is placed.

shading with anisotropic

change in freshnel index





change in roughness





change in spread Y





change in spread X





change of angle


default values

shading with phongE

specular color=red






whiteness color=red





highlight size=1





highlight size= 0.010


Roughness=0.1



Roughness=0.010





default phongE attributes

Blinn and Phong

phong attributes



blinn attributes






phong attributes



blinn attributes

from left to right: default values for lampert, blinn, phong and phongE

shading with blinn

watch the blinn's (green pear) highlight change position as the view-point moves

shading with phong

reflexivity 5



reflexivity 0.005



reflexivity 0.500(default as all others)



cosine power=20
specular color=green



cosine power=20
specular color=blue



cosine power=20
specular color=red




cosine power=200



cosine power=2



default phong value (look pear)
cosine power=20
