The puzzles from this category perform various operations with objects.

show

Makes a specified object, that was initially or previously hidden, visible. Also works for a list of objects, a group (or a list of groups) or with the all objects puzzle. If there is no such object(s) present in the scene, or an object is already visible, does nothing.

hide

Makes a specified object invisible. Also works for a list of objects, a group (or a list of groups) or with the all objects puzzle. If there is no such object(s) present in the scene, or an object is already invisible, does nothing.

is visible

Checks if an object (or any of objects in a list) is currently visible. If it so, returns the logical value true, otherwise returns false. If there is no such object(s) present in the scene, returns false.

clone

Makes an object copy, generates a unique name for the new object and immediately adds it to the scene. Outputs the new object. Does not work with lists, groups or the all objects puzzle.

create object

Creates and adds a new object to the scene. This puzzles creates objects without the need in a 3D editor, and as such is useful for learning Puzzles as well as designing primitive visuals by users with no or minimal 3D modelling skills.

For geometry objects, such as boxes or teapots, this puzzles also creates white-colored dielectric glTF-compliant PBR material (with roughness value set to 1 and metalness set to 0). Use set color and set value puzzles to tweak that material.

remove

Removes a specified object from the scene. Also works for a list of objects, a group (or a list of groups) or with the all objects puzzle. If there is no such object(s) present in the scene, does nothing.

set transform

Moves, rotates or scales an object according to specified transform data. The "offset" checkbox enables moving/rotating/scaling an object relatively to the original position/rotation/scale. Any of the axis inputs can be left blank. Also works for a list of objects, a group (or a list of groups) or with the all objects puzzle.

get transform

Retrieves the position, rotation or scale data of an object. Does not work with lists, groups or the all objects puzzle.

change local transform

Moves, rotates or scales an object according to specified transform data in its local space. Any of the axis inputs can be left blank. Also works for a list of objects, a group (or a list of groups) or with the all objects puzzle.

snap to object

Moves an object to the position of another object by copying its transform data. Also copies rotation and scale. Does not work with lists, groups or the all objects puzzle.

parent

Creates a parent relation between objects, so that the first object follows position/rotation/scale of the second one. Does not work with lists, groups or the all objects puzzle.

Specify <none> as the second value to unparent the object.

set object direction

Set an object's direction to the point/vector with X, Y, Z coordinates. The point checkbox specifies whether the X, Y, Z coordinates belong to some point in 3D space or represent a direction vector. The lock up checkbox locks the up-down axis of the object so it remains perpendicular to the horizontal surface.

get object direction

Returns an object's direction vector or numeric X, Y, Z vector components.

get objects from

This universal puzzle allows you to:

get the list of objects contained in a group thus making it iterable
convert the output of the all objects puzzle to a list thus making it iterable
get children of some parent object

By using the dropdown you can also filter off objects of a kind (e.g. cameras, lamps, annotations, etc).

get morph factor

Returns an object's morph target factor.

set morph factor

Sets an object's morph target factor.

Example:

See the source files of the Parametric Models demo and also this video tutorial explaining the basics of using morph target puzzles.

add annotation

Adds a point of interest icon to an object that a user can expand by clicking on it to see some description. Also works for a list of objects, a group (or a list of groups) or with the all objects puzzle.

Notes:

This puzzle creates 2 HTML elements which can be styled with CSS using their classes.

You can also style each individual annotation by assigning and accessing its elements' ids.

By default, an annotation oscured by some geometry is automatically closed and become semi-transparent. This behavior can be disabled by turning off the fade annotations option of the configure application puzzle.

You can use a more low-level alternative, the bind element puzzle, instead but it won't expand upon clicking and won't be obscured by geometry.

remove annotation

Removes a previously added annotation from an object. Also works for a list of objects, a group (or a list of groups) or with the all objects puzzle.

open annotation

Expands an annotation specified by its label.

close annotation

Closes an annotation specified by its label.

update text object

Generates a new mesh for a text object according to specified textual content. Also works for a list of objects, a group (or a list of groups) or with the all objects puzzle.

distance

Outputs the distance between two specified objects. Does not work with lists, groups or the all objects puzzle.

get custom props

Returns a dictionary with custom properties assigned to an object.

Custom properties can be assigned in Blender by using the Custom Properties panel:

or in 3ds Max by typing properties in the Object Properties dialog:

or in Maya by using the Attributes->Add Attributes... menu in the attribute editor:

In case of Maya you need to assign additional customProperties attribute with the list of space-separated custom property names.

outline

Applies or removes the outline effect to/from a specified object. Requires enabling the outline effect in Blender, 3ds Max or Maya. Also works for a list of objects, a group (or a list of groups) or with the all objects puzzle.
