description
Textures can add realism to improve the appeal and to add details to simulation results so that they are more likely to be appreciated, they might be easier to compare to test data. There are also advanced ways to use textures which go beyond using them for realism or for logos. That usage is covered in another presentation on textures in EnSight.

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

Color by variable but use texture for opacity

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
• http://astronomy.swin.edu.au/~pbourke/texture/

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
