A little help needed on getting started on animation and scenes using Ruby. Yes, I am comfortable with developing plugins for Sketchup. My question is as follows. I see two sets of APIs for animation. One is the Animation object and using the nextFrame method (su_examples has a animation.rb which m…

[image] raprmavi: The loops typically run thru very fast. How do you give the feel of slow animation. Or is that done outside of sketchup when you stitch them together You can slow things down by moving a shorter distance each frame, or putting in a delay as @DanRathbun mentioned. A code snip…

although warned about bumping the topic… due to the slowness of rotating large amounts of geometry, I’ve been trying to create a similar visual result by rotating the camera, targeted on the same entity.bounds.center… to avoid the jump from camera.target to bounds.center I added an incremental ste…

[image] john_drivenupthewall: is there a better way? From what I understand, you just want to interpolate position (keeping camera direction the same). The target needs to be adjusted as well. I haven’t tested this, but Point3D linear combination could be used as follows: . . . initial_posn …

can’t upload gifs at the moment, unfortunately… for each step [360 in full code] I change the camera.eye and camera.target… I did’t want to create 360 new cameras so I’m using cam.set(eye_point, target, up) up is the eye point is from an array of points defined by a planar circle at eye height c…

Although you can use #offset or #offset! on Array or Geom::Point3d objects, many coders forget that they (and Geom::Vector3d objects,) can be transformed. In this scenario it doesn’t matter whether #offset or #tranform is used as they both take a vector object. Leaving the eye in the old place and…

cheers, that works for me if I use eye = cam.eye # leave it as is aim = cam.target.transform(vec_t) up = cam.up # leave it as is cam.set( eye, aim, up ) otherwise it will flip when the model is inverted… next issue is can rotation around bbc[0], bbc[1], eye…

this is what I’m wanting to replace with a camera animation on larger models… [image] in my extension, the code is always run on a locked group so I’ve modified it for testing remotely… oddly, sel.add(ents[0]) if sel.empty? only highlights the group on the first run… def spinit model = Sketc…

I can now see what you wanted. You said: [image] john_drivenupthewall: due to the slowness of rotating large amounts of geometry Animating the camera avoids logging of edit…undo operations. Instead, you could select all the objects and group them into one entity. They could be rotated with a…

on up to 30MB files both seem about the same… on a 126MB test file, that takes 70 minutes to process before the spin, the camera move is step-y but much faster… it always happen on a pre-positioned locked group… the whole process up to the spin is in a tmp file, and the spin, blocks SU from servi…

[image] john_drivenupthewall: oddly, sel.add(ents[0]) if sel.empty? only highlights the group on the first run… Confirmed also on PC v 2016. The bug here is that the selection set is not empty, but the items are not highlighted. Calling sel.add(sel.to_a) does nothing. It does not remove the…
