Python states and StrokeState anchor new curves on existing 2024年2月22日8:35
Well so there's a ugly answer to that question but i'm sure there's a better way.
Make a feedback loop to the draw curve itself (in a one iteration loop) and move the curves on the plane they originated from :

// Find the prim the current point belongs to, then store the point ID // of the first point in that prim int point_prim = pointprims(0, @ptnum)[0]; int first_point_id = primpoints(0, point_prim)[0]; // Use projection attributes stored on the stroke primitive // to move points vector p0_orig = point(0, "stroke_orig", first_point_id); vector p0_proj = point(0, "P", first_point_id); float dist_to_p0 = length(p0_orig - p0_proj); v@P = v@stroke_orig + ( normalize(v@stroke_dir) * dist_to_p0 );
Python states and StrokeState anchor new curves on existing 2024年2月22日6:35
Hello
I want to build an hda that uses the stroke node.
Strokes would be drawn in screen space. When a new stroke is about to be made the hda will be able to intersect with a previous curve and set the projection center to that point.
I copied that snippet that work with the class State(object) I believe.
It is able to get the pos in space for the intersect.
Unfortunately that put in class(StrokeState) doesn't do anything.
Is there a way to achieve that for strokestate on prestroke for example ?
Thank you so much in advance.

geometry = self.node.geometry(0) origin, direction = ui_event.ray() position = hou.Vector3() normal = hou.Vector3() uvw = hou.Vector3() intersected = geometry.intersect(origin,direction,position,normal,uvw) self.node.parmTuple(f"stroke_projcenter").set(position)

sequence of stills seen as a sequence in cop 2018年3月7日20:25
Hello forum
I'm loading automatically a set of images in cop and these images have a the same number in their filename,
Something like xxx_T200_basecolor.png T200 stands for tile 2meters.
On each frame there's a different image but all of them have T200 inside their filename.
Because of this they're seen as a sequence and xxx_T200_basecolor.png is interpreted as frame 200
So is there a separator that would make things more clear for houdini?
Tried the override but it's still a sequence.
Any clue on how to resolve this would be appreciated since i'm stuck for two days on this problem.
Thank you.
