2d drawing in ex9

Hallo

I am working on animation project which mix drawing and colaging cuted pictures.
But i stack in some places, i hope you could help me.

I made some patch for drawing and i am not sure if that’s the right way.
Can u look at that guys and help mi if there is any simplest solution.

edit:
i have used texture render becose i need see the cursor, and if i turn of clear the sursor is drawing by it self.

Also is there possibility to draw 2d polygonal shape but not made from polygons?
I have try to draw shape with polygons with floating middle vertex but in some kind of shapes it doesnt work.
There should be easier way to draw 2d shape.

And also i am cutting images using two layers through blend. On one of theme is white shape which “cut” the img upon that.
Can vvvv somehow save img with the alpha channel, something like keying to color?

thanks you for answer
hope not to much at once and in bad place.

btw! thanks for VVVV its amazing software, my roots are in PD but i hope i will get fast into V

Lot of questions, welcome to the forum :)

Next time, just attach the patch, so we can look at it, and modify stuff when needed.

There is a queue node that lets you queue (memorize) all the values you have drawn, might also be an option.

For saving with Alpha, the DX9Texture node has some hidden pins, watch them in herr Inspektor. You want to select any format with an A in it (a for alpha) like A8R8G8B8.

You also want to set the Background color of your renderer to no alpha, with for example a Setalpha node.

This will pass transparency to the texture, wich you can now save with the Writer (EX9.Texture) node, you need select a picture format that supports alpha, like .PNG.

I attached an old drawing patch I have made, a big mess, not to happy, but it will show you how to save in alpha.

For the Polygon question, no idea what you mean, sorry here.

Thank you
I know is a lot of question i am new one month and i want to know all in once :)

Thats nice patch man.
Before i saw also one (spray painting) patch based on queue, but i was afraid of how much data can this node absorb.
Have u tried limit of queue node?

about polygon
i imagine something like drawing vector object which can be of any possible shape and filed by color. The object is draw by position of vertexes.

here is my patch for vector drawing but the shape is depend of middlepoint, ill appreciate if u tell me something bad about patch to improve for nex time.

thanks a lot
all the best
