Write JavaScript that builds objects with the BO helper, then press Run. Objects land in the scene as single selectable, keyframe-able items.
BO helpers
BO.box(w,h,d,opts) · BO.cylinder(rTop,rBottom,h,opts) · BO.cone(r,h,opts) · BO.sphere(r,opts) BO.group(name,[children],opts) · BO.add(obj,name) · BO.fit(obj,height) · BO.clear() Rig: BO.joint(name,[parts],{x,y,z (hinge point), axis:'x'|'y'|'z', min, max (degrees), auto:{radius,open}}) — put the result inside a group Rigging: BO.joint(name,[parts],{x,y,z,axis,min,max,sign}) makes a hinge with a slider · BO.link(a,b) makes b follow a · BO.jointOn(node,name,opts) · BO.roll(obj,[{node,axis,radius}]) rolls wheels with travel Scripts can use await (fetch files, load models) opts: {x,y,z, rx,ry,rz (radians), color (0xRRGGBB)} — ground is y = 0, front is +z. THREE is also available.
Camera Block-Out
What it does
Block out a scene with simple objects or imported models, animate a camera move with keyframes, and render it to a video you can use as a motion reference for AI video tools like Seedance.
How to use it
Add primitives or import a GLB, GLTF or OBJ model.
Orbit the view and add a keyframe at time 0.
Drag the timeline, orbit to a new view, add another keyframe.
Press Play to preview, then Render video.
