2D Textures

• What is a 2D texture?

– A way to apply an image to an object

• Why?

– Easier for audience to understand simulation

– Improve realism

– Different visual effects

• Color by a variable, transparency by a alpha texture

2D Textures

• Options

– Control location and orientation using the plane

tool or node ids

– Control how the texture “blends in”

– Can compute the texture coordinates

– A texture can have opacity

2D Textures

• Where do they come from?

– Any supported image file

– Web sites

2D Textures

• Steps

– Load a texture

– Orient the plane tool (or compute s & t

variables)

– Color the part by the texture and grab the plane

tool coordinates

– Repeat or clamp

– Decal vs. modulate

2D Textures

• Texture on a moving

object

– If the part is transient

the texture will “slide

off” unless you

reference the origin

and s & t vectors using

node idsExample using plane orientation
