ProjectX and CylinderZ #13

Closed markingle closed 7 years ago

markingle commented 7 years ago

What is the difference between these two parameters?

MarkWheadon commented 7 years ago

projectX projects the image onto the X axis (as if the X axis were a projector screen) -- so the image runs through the model like words through a stick of Blackpool rock.

cylinderZ wraps the image round an upright cylinder, so it appears as if it has been wrapped around the model (so great for vases for example).

Does that help?

Yes it does! Thanks Mark! I designed a "vase" for my wife and I would like to put hearts in a checkers board pattern on the outside using velPaint. It sounds like I should use projectX?

I took the day off work to get this going...lol

Not quite checkered but progress none the less! (see middle bottom)

Here is the command I used:

./velPaint -projectX 0 0 22 20 0 3000 1800 3000 /Users/Mark/Downloads/Heart.png /Users/Mark/Downloads/MyHeart.gcode > MyHeart_VP.gcode

How do I config for a checkered pattern?

I figured it out! After thinking about it a little more its as simple a choosing a png file with the pattern that you want. Using the projectX switch "projects" the checkered pattern image on to/through the object!

Excellent work Mark W.!
