Quick Start



Blocker is an augmented reality directors viewfinder. This guide will go over how to place characters in your environment, photograph them with one of our camera presets, then manage the photos you’ve taken in your gallery.

Find Surfaces

Blocker relies on Apple’s ARKit to track your phone’s position and detect planar surfaces to place characters. To begin tracking your phone, gently move through you environment. The reticle helps visualize where models will be placed. When the the reticle displays a white dot in its center, it is over a detected surface. When the white dot is missing it is using an approximate surface.

The reticle will appear larger when it is closer to you. This can be a useful cue for determining whether a model will be placed on the ground or a surface such as table.

Add models to your scene

To add a model open the asset library using the block button in the lower left of the screen. Tap on the desired model. The model will be placed on top of your reticle.

Manipulate Models

Once you’ve created a model it is possible to move, scale, rotate and delete models with simple gestures.


Models can be positioned simply by tapping and dragging them. While dragging they will snap to planer surfaces beneath them. If a new surface has been detected, you can ground your objects by dragging them.


Models can be scaled using a pinch gesture. The height of the object is displayed above the model.


Models can be rotated by using two fingers and rotating them around a central point. If you choose, it is possible to scale and rotate at the same time.


To delete models swipe over them.

Director’s Viewfinder

Blocker is capable of simulating the framing of a variety of camera models at various focal lengths. The Complete Camera Pack is an in app purchase that provides over 400 models. By default, the camera model is a generic 35mm camera with a 16:9 aspect ratio.

Once you’ve purchased the Complete Camera Pack you can change your camera model by clicking on the camera name at the top left corner of the screen. This opens a menu organized by the make, model and sometimes camera settings.

You can adjust the focal length by sliding the zoom ring at the bottom of the screen. The current focal length is displayed in the center of the ring.

The focal range is displayed at the top right of the screen. To adjust the range, click on either the low or high range and enter your desired focal lenght.

Taking Photos

To capture a photo, simply tap the shutter button on the right of the screen. When you back away from the location that you took the photo, you will see a virtual camera indicating where you took the photo. If you tap on the virutal camear, it will display the camera frustum and additional photo stats.

Captured photos are saved to the app’s internal gallery and can be exported as either invidivual photos or as storyboards.

Export individual photos

To export individual photos tap on one ore more photos, then click on the down arrow icon. This will send the photos to Apple’s default share modal where you can save to your photo gallery, email or text the series of images.

Export a storyboard

Just like exporting individual photos, tap to select a series of photos. The numbers displayed over the photos indicate the order that the photos will be placed into the storyboard and the order is determined by the order the photos are selected. To generate the the boards, press the icon with the down arrow and grid. This will generate one or more pages of the storyboard and send the pages to Apple’s default share modal.

Delete photos

Finally, to delete photos, tap to select on more photos, then click the lower left garbage can icon. You will be prompted to confirm you deletion, selecting “Yes” will permantly delete the photos.
