Tutorial 4: More Breeding

This concepts presented in the tutorial are very similar to those of Tutorial 3. The major difference is using a different database of shaders that is more complex and may take more time to generate. This tutorial assumes that you are familiar with the concepts and tools presented in tutorials one to three.

1. Project Loading

Enter the software, hit File->Load Project ..., and bring up (1):

/usr/local/genshade/prman/examples/gs_01012000_16_sur_complex.prj

The GUI looks like:

2. First Generation

Select two parents option from the pool option at the tool bar, which should have already been selected by default.
Select patch option from the geometry option at the tool bar.

Tool Bar

Copy child C19 image and data, from the current population pool to parent 1 cell
Copy child C26 image and data, from the current population pool to parent 2 cell

Hit Generation->Generate Once ..., submenu.

The first generation begins which should not take more than few minutes creating 27 new shaders (results vary depending on the generation parameters used).

3. Second Generation

Copy child C4 image and data, from the current population pool to parent 1 cell
Copy child C12 image and data, from the current population pool to parent 2 cell

Hit Generation->Generate Once ... submenu.
When the generation is complete, pick your favorite images of shaders and copy them into the Storage Pool

4. Third Generation: breeding of the same shader

Copy child C23 image and data, from the current population pool to parent 1 cell
Copy child C23 image and data again, from the current population pool to parent 2 cell
Hit Generation->Generate Once ... submenu.
When the generation is complete, pick your favorite images of shaders and copy them into the Storage Pool

5. Saving the Results into a New Shader Database

Hit File->Save Storage Database ... submenu, select the name of your new shader database, and click OK.
select your top shader
Hit File->Save Selected Child -> all to save an individual shader

Here is a selection of the stored shaders:

(1) Your sysadmin may have installed the software somewhere other than /usr/local. If so, look at your $GENSHADE_DIR variable, and use that instead of /usr/local/genshade in the above example.
