extrude

[liors17841744]

hello 

i'm trying to duplicate a layer along a path.

i managed to do successfully - by using a mask path.

but mask path is only 2d...

now i want to do it in 3d - best way to describe it would be like auto-orienting a layer along a 3d path - just instead of movement i need duplication to occurs.

there's a cool plugin that took this functionality to the extreme: BAO Mask 3D Warper Extrude using a Light Path Tutorial - YouTube

there's also "trapcode TAO" that do it, but it's limited to its own kind of shapes.

what would be the general steps to do it?

i already figured out that i would have to read a path from a position property which allows for 3d.

any help would be more than greatly appreciated!

Sadly, the API offers no tools for rendering 3D transformations. (for 2D

there's transform_world())

you'll have to come up with your own 3D transform algorithm and render the

image instances along the path.

thanks for your sad-quick reply...

any recommendation on the best way to do it?

it it reasonable to say that i should calculate the transformation myself and then

use the current transform_world to "fake" 3d look. (using scale, rotate, etc..)

imho, it would look ok. but if you ever compare it to real 3D... you'd go

"aw, that's a whole different level"...

look into the "Artie" sample project. there are some macros there for

getting the XY coordinates of a texture using a 4X4 matrix. if you don't

care for antialiasing, then that code could be used for a quick setup of a

3D transform function. perhaps you could use that for a "prof of concept"

before diving in...

Hi!

You could also take a deeeep breath and jump into OpenGL... That's what Trapcode's Tao and most of Bao plugins use.

It's a real nightmare in the beginning, then you see a lot of possibilities and can have a lot of fun. And then it's a nightmare again 😉

You can start with the GLator sample plugin, and have a look at the related threads on this forum.

Cheers,

François

ps: glad you like Mask 3D Warper !

leroy that was an amazing advice, saved me tons of time.

i also really like the BOA Boa plugin

Glad it helped!
