GLS TReal help
Change Leaves to proxies aka GLScene Tree.
Tree types need alternate, dual-opposite, other?
...
- Similar to TReal, yet different somehow
- Image of a Tree is traced to derive input to the Tree for display in GLS 3D.
- All Tree definition files are to be located in the 'tree definitions' directory. All images and shape files are to be in the 'tree data' directory. All Help is located in the 'help' directory. All 3 are sub-directories of wherever the GlsTReal.exe and POVTreal.dll are located.
- The form contains a menu, tracing display (the tracing area can be minimized when not being used: note the dark line between the form pages and the image display on the left), and data input:
- Tree Definition File:
- Load, Save, Display(wo leaves), Set up Printer, Print annotated .tdf, Save annotated .tdf as a .txt file, Help, Exit (Quit the program)
- The Tree Definition File (.tdf) filename selected
- Basic parameters
- Shapes: conical,
spherical,
hemisperical,
cylindrical,
tapered cylindrical,
flame,
inverse conical,
tend flame, and
envelope (pruned). The same tree data can be displayed using different shapes to make 'variations' of trees. Some trees are always a specific shape, while other trees can grow into various..any shape (Ginko).
- Random Seed (to be able to repeat a tree.. randomly)
- Levels.. normally 3 levels are enough. The other levels are still visible, the labels are lightened and any data will NOT be saved. This implementation has 7 levels available (0..6) plus Leaves and Fruit.
- Season: percent and color of Leaves on the tree. Winter: no leaves..(dead on ground in POV), Spring: smaller leaves, Summer: Leaves as entered, Fall: Brown leaves (in POV, no effect if texture used)
- Health : percent less leaves .. would rather have it be (someday): percent randomly located dead (leafless) branches. A percentage of 'dead' branches rather than what could be done by changing the number of leaves to be made.
- Distance : the Range degradation control
- Wind: Speed, Gust, (Direction) determine the amount of affect on the tree. The little box toggles an initial use of the Wind parameters. In the GLS tree viewer an AVI can be made cycling through wind blowing the tree. (someday.. currently will make 360 frames of a stationary tree)
- Sun Height, Strength, Direction... none are implemented... Locate the Light source. Probably do in POV and simply have an interactive Light controller that starts with the parameters in GLS.
- Status Bar displays comments [Tracer activity: the number of Points selected (did that one 'take')]
