1. EnSight analyze, visualize, communicate 2D Textures in EnSight example without texturesexample with textures

2. EnSight analyze, visualize, communicate 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

3. EnSight analyze, visualize, communicate 2D Textures example no textures

4. EnSight analyze, visualize, communicate 2D Textures example with textures

5. EnSight analyze, visualize, communicate 2D Textures –Traditional techniques Isosurface of COClip of temperature

6. EnSight analyze, visualize, communicate 2D Textures Color by variable but use texture for opacity

7. EnSight analyze, visualize, communicate 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

8. EnSight analyze, visualize, communicate 2D Textures Where do they come from? –Any supported image file –Web sites http://astronomy.swin.edu.au/~pbourke/texture/

9. EnSight analyze, visualize, communicate 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

10. EnSight analyze, visualize, communicate 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 ids Example using plane orientation

11. EnSight analyze, visualize, communicate 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 ids Example using node ids for orientation

12. EnSight analyze, visualize, communicate Embeded Video Realistic comparison Time syncing features Full 2D Texturing capabilities
