Seminar Modeling Exercises

A. Getting Started

1. Open up house.blend (from the blenderExamples folder) and practice the Mac or Window commands
2. Open up the vein.blend (from the blenderExamples folder) and practice making your own veins (use combo for curved veins), practice dividing and smoothing and pulling off veins

B. Using Reference Images

3. Download Jing, examine reference images and body slices (see links above)
4. Split screen and load front circulation image on right side (from referenceimages folder), top body slice image 1 on left side (from body slices folder) and adjust image
5. View nucleusinc heart video (see link above), and model three primary arteries, use hide elements (use heartcircle.blend starter file)
6. Combine veins and arteries (use a plane reference) to be attached to the heart (start with heartsvcpaarota.blend file)

C. Changing Reference Images

7. Load heart reference image on right side (from referenceimages folder image 1), and body slice image 4, 3, 2 from (from body slices folder) as your model, use hide elements
8. Connect veins to heart, subdivide and smooth (see heartveins.blend, heartveinsSmooth.blend in blenderExamples folder)

D. Texturing Your Heart

9. Demonstrate editing vertices, dividing surfaces, and smoothing .
10. Demonstrate marking seam and unfolding.
11. Demonstrate coloring in gimp & image import/texturizing into photoshop

E. Placing Your Heart on the Web (it’s safer than e-harmony)

12. 11. Load into Papervision3D or CS4 (don’t forget to triangulate), use XML exporter, and place on the web.
