GeoGraffiti

images/download/attachments/41798462/viz_icons_geograffiti.png

The Graffiti Texture plug-in gives the ability to draw freehand on top of containers with the Globe plug-in. The freehand draw is created with a brush shape, used with a mouse. The plug-in can also recognize some rendered shapes, such as circles, ellipses, crosses, and arrows, and replaces the hand-drawn item with the recognized shape.

The plug-in can either work in combination with Viz Engine’s multi-texturing technology or can add a standalone texture.

Note: This plug-in is located in: Built Ins -> Container plug-ins -> Texture
