thick point : the primary
point defines the middle of a circle or drop. Move it with the mouse or
set it by clicking the left button.
thin point : the secondary point is used to set the size of a circle or define the second point of a line to be drawn. Move it with the mouse by holding the left button or set it by clicking the right button. |
The drawing functions allow you to perform
operations which are limited to specified areas.

The line goes from the thick to the thin point and has a constant width which can be defined on the line thickness control bar. Lines can be added and subtracted from the texture. |
![]() |
The circle adds the current color to the texture. The brighness of the added color is dependent to the distance to the middle of the circle (thick point). Circles can be added and subtracted from the texture. |
![]() |
The blending drop is handled like the circle but the added color is a phong shaded sphere. The highlight of the drop is exactly between the thick and the thin point. |
![]() |
The blending square is very similar to the drop, but has different edges. |
![]() |
The flash is like the line. It goes from the thick to the thin point. It spreads by approaching the thick point. |
![]() |
A blob consists of a big and a small circle that are blobbed. The big is arround the thick and the small is arround the thin point. Blobs have a miximum size and tear if the distance between the points is to high. It can only the interpolated (not added) and subtracted from the texture. |

This circle function contracts the pixels of the texture within its own area. Use it several times on the same place to get some ribbons. |
