Use Add to Favorites option from the action menu to add the current spot to your favorites. Just enter a name and tap the OK button. The app will create a thumbnail for your spot using the current image.
Use the folder button to open the gallery with the last visited item selected.
Use tabs to switch between your favorite spots and built-in examples. Tap an item to open it.
Use the sort button on the bottom to sort items by name, fractal type, paint mode, palette, light mode, or image filter. When sorting by fractal type, you may choose the order: alphabetical or the order in which fractal types appear in their list (built-in first). The same goes for sorting by palette, paint mode, light mode, or image filter.
Every spot is described by a thumbnail, a name, and a description depending on the selected order (a fractal type name, a paint mode name, a palette name, a light mode, or an image filter name). Spots using advanced features are labeled adv on the right.
Use the search button on the top to search items. The search criteria depend on the item order. For example, you can sort items by fractal type, and easily find all the examples that use a specific fractal type. When you open an example and then come back to the gallery, the app will keep your searching criteria. You may use this feature to organize your favorites like in folders.
Tap the close button to leave searching, and show the tabs and the sort button.
In the free version, the examples using the Premium features are marked with icon on the right. They can be opened only in preview mode, without the possibility of any change, except selecting the Supersampling option (you can even use the options normally locked in the free version).
Long press an item to show a context menu containing the following options:
|View||Choose the spot (the same as tapping it).|
|Zoom video||Start real-time zoom video to the spot.|
|Apply style to current||
Apply the selected item's style (palette, paint mode, light, and image filter) to your current image.
NOTE: applying a style to a different fractal and/or coordinates may not reproduce the appearance of the style source location.
|Open with current style||Open the selected item applying the style of the current image.|
|Share||Share your favorite spot.|
|Rename||Change the name of your favorite spot.|
|Replace with current||Replace your favorite spot with the current image.|
|Delete||Delete your favorite spot.|
Use Save Image option from the action menu to save the current image or render a high resolution image for the current spot.
The app saves the image in the device's gallery. The filename is MandelBrowser_<date_time>.png (eg. MandelBrowser_190731_181501.png).
NOTE: you are free to use the images generated with the app for any purpose, this includes the app's built-in examples.
After selecting the High Resolution Rendering option, you will be asked to set the image options described in the following subsections. Then use the START button at the top of the screen to start rendering the image.
While rendering, the app shows a preview of the image, progress, and the estimated time remaining (after 15 seconds, if it takes more than 30 seconds). The remaining time estimation may be inaccurate, but it should at least give you some idea of how long it will take.
The image is rendered in parts, and each part is displayed on the preview only when it is finished. When the current spot uses an Image filter, the preview doesn't show the result of applying it. The filter is applied when the image is ready.
When the image is ready, the app saves it to your device's default image folder and displays the file name. Saving a large image may take 30 seconds or more.
You may use the STOP button to break the image rendering. The rendered part will not be saved.
Choose from the available image resolutions from 1080 up to 7680 (8K UHD). On Android versions earlier than 10, the resolution is limited to 5760 (6K UHD).
Unlock the Premium get access to the resolutions higher than 1920 (FHD).
WARNING: rendering 8K images requires a device with at least 4GB of RAM memory. Successful rendering is not guaranteed if your device has less memory.
Select Custom resolution and tap the image size (where icon will appear) to enter your preferred image size in pixels. Aspect ratio for the Custom resolution is limited to between 20:1 and 1:20.
When using a built-in resolution, choose from the available aspect ratio values. The options are 1:1, 5:4, 4:3, 16:9, 4:5, 3:4, and 9:16.
Choose from the available Supersampling settings.
Use Save Video option from the action menu to open the Video menu. This feature is not available on the devices with Android versions earlier than 6.
NOTE: you are free to use the videos generated with the app for any purpose.
|Zoom-in video||Create a zoom-in video to the current location, starting from the fractal's default zoom (or minimum zoom if the current is below the default).|
|Zoom-out video||Create a zoom-out video from the current location to the fractal's default zoom (or minimum zoom if the current is below the default).|
|Palette flow video||Create a video with a color animation on the current image.|
|Set transition start||Set the current location as a starting point for a transition video.|
|Restore transition start||Open a previously set transition starting location (e.g. to be able to modify it).|
|Transition video||Create a transition video from the previously set starting point to the current location.|
After selecting the video type, you will be asked to set the video options described in the following sections. Then use the START button at the top on the screen to start rendering the video.
While rendering, the app shows a preview of the current frame, progress, and the estimated time remaining (after 15 seconds, if it takes more than 30 seconds). The remaining time estimation may be inaccurate, but it should at least give you some idea of how long it will take. When the image is particularly complex and it takes a long time to render a single frame, the app shows the progress of the current frame as a bar at the top of the frame preview image.
You may use the photo button to save the image of the current frame.
When the video is ready, the app saves it to your device's default video folder and displays the file name. The video filename is MandelBrowser_<date_time>.mp4 (eg. MandelBrowser_210217_181501.mp4).
You can use the STOP button to break video rendering before the end. In this case the finished part will be saved.
The options described below are available for all video types.
The default values for all options are most recently used values. It also applies to the options specific to the video type.
Choose from available video resolutions from 144p up to 1080p.
NOTE: using low resolution 144p can be a good choice for creating video preview quickly just to make sure that the selected parameters have led to the result that meets your expectations. After that you can run the video creator again with the desired resolution. Rendering 144p video can be over 50 times faster than 1080p video (and over 1500 times faster than 1080p video with 5x5 supersampling).
Making 144p videos is freely available. Unlock Premium to use higher resolutions.
Select Custom resolution and tap the image size (where icon will appear) to enter your preferred image size in pixels. The size is limited to 2160 (1080 on Android versions earlier than 7). The size may be further limited by the capabilities of the device's embedded video codec.
Aspect ratio for the Custom resolution is limited to between 2:1 and 1:2.
When using a built-in resolution, choose from the available aspect ratio values. The options are 1:1, 5:4, 4:3, 16:9, 4:5, 3:4, and 9:16.
Choose from the available video frame rate values from 24 fps to 60 fps.
Choose the video quality.
The app automatically calculates and displays the bitrate basing on the quality and resolution selected. The estimated video size is also displayed.
You can change this setting only in the Premium mode.
Choose from the available Supersampling options.
Using supersampling optimization may be a good choice, as any remaining inaccuracies are unlikely to be seen in the video.
The app displays the predicted zoom video duration.
For a palette flow video and a transition video, you can set the desired duration.
Select the length of the fade-in and fade-out effects for the video.
The app automatically scales the elevation used for computing light. This may cause undesirable changes in lighting during a video when you use Light 1 or Light 2 mode. You can select one of the following options to get the result you prefer.
|First frame||The first frame elevation scale will be used for the entire video. The light will be stable but the surface may get too flat or too convex if the elevation range varies significantly during the video.|
|Current frame||The elevation will be scaled for each frame separately. This may cause light flicker (but sometimes you may want it).|
|Moving average||The elevation will be scaled basing on a moving average over the last second. This minimizes flicker and takes account of elevation range changes during the video.|
When video rendering fails or produces an empty video, there is a chance that changing the Settings / Advanced video settings may help.
Set the initial zoom factor (for a zoom-in video to the current location) or the target zoom factor (for a zoom-out video starting at the current location). The default value is the fractal default zoom factor, or the fractal minimum zoom factor if the location zoom factor is equal to or less.
When creating another video for the same spot (same fractal type, coordinates, and zoom factor), the app proposes a previously used value by default.
Select the zoom speed from the available presets, or the custom option to provide your own value.
The higher the value, the faster zoom, and the shorter a video. The value of x2.0/s means, that the zoom scale changes by a factor of 2.0 in one second.
Choose whether and how the zoom speed will decrease when approaching the end of the video.
Choose whether the app should generate an image for each video frame, or use one for several frames to reduce the rendering time. You can select one of the following options.
|Off||An image for each frame will be rendered. This setting will take the longest time to generate the video, and the image during the video may flicker in areas containing a lot of details (not possible to accurately capture at a given resolution).|
|Shrink||One oversized image will be used for several frames by shrinking (no quality loss).|
|Stretch||One oversized image will be used for several frames by shrinking or stretching up to 100% to save rendering time. This is the fastest option, but at the cost of slightly degraded quality.|
NOTE: when using the Supersampling, the Off option is used.
NOTE: in the Advanced mode, you can set palette flow options separately for the fractal's exterior and interior.
Select the color flow direction.
Select the color flow rate in palette cycles per second. The lower the value, the faster palette flow. The value of 0.2 cycle/s means, that one complete cycle takes 5 seconds.
Select the video duration from the available presets: 10, 20, 30, and 60 seconds.
The available speeds and durations are matched so that the video will contain complete cycles and can be played seamlessly in a loop.
Both the start point of the transition video and the end point must use the same:
This may seem limiting, but there are actually many settings left that may have different values in the start and end locations:
When the value of a specific parameter differs between the start and end locations, the app interpolates its value during the video. When the parameter uses logarithmic scale on the scrollbar, the interpolation will also use logarithmic scale.
If there is a difference in the palette offset, the app interpolates its value by taking the shorter path. This means that interpolation from 0.2 to 0.8 will go over 0.
Select the rotation direction. This option is available only if the transition target has rotation angle different than the transition starting point.
The default value takes the shorter path. When you change the value, the app will use your selection the next time you create transition video for the same start and target locations (same fractal, coordinates, zoom and rotation angle).
You can choose the movement pattern from the available presets including linear motion, harmonic motion, and other less usual options. The app displays a small chart illustrating the outcome of the chosen option.
Set this option to create a transition video from the selected start to the target, and back to the start. This may be useful for creating videos that can be played in a loop.
Set the video duration from 1 to 500 seconds.
Use the Share option from the Action menu to share the current image or the app's deep link to the current spot. You may also share a link to your favorite spot using the Share action from the context menu of the Favorites list.
If the location uses user-defined content (a custom fractal type, paint mode, or palette), the app sends a text file instead of a link. That file contains the necessary custom fractal type, paint modes, and palettes, and can be opened using Import Custom Content from File option.
To open the link received in a message just tap it, and choose MandelBrowser as the app to open it when requested.
When you received a link that is not clickable, just copy the link (or even the entire text of the message), choose Import option from the Action menu, and select the Paste Location Link.
NOTE: if the link was opened in the browser despite having the app installed, the solutions may be as follows. On Android 12+, you may need to enable links in the device settings / Apps / MandelBrowser / Set as default. It's also possible that an app or a website displaying the link prevents deep links (as they use redirection to track the links you click). In this case, you may use the solution as for non-clickable links.
When saving the image, the app uses the image EXIF data to store the location link (including your custom content if necessary).
You can open the location from the image created with the app by choosing Import option from the Action menu, and selecting the Open Location from Image.
The app will send a text file containing the selected custom content.
Download the file or save it to the Drive. Then open the file by choosing Import option from the app's Action menu, and selecting Import Custom Content from File.
If the file contains a custom fractal type, paint mode, or palette that already exists, it is skipped. The app compares the definitions, ignoring names and descriptions.
If your custom content already contains another fractal type, paint mode, or a palette with the same name, the app changes the name, for example, 'My palette' is changed to 'My palette (2)'.
After reading the file, the app will list the new custom content and ask for confirmation.
If the file contains a location, the app will open it.
Use the Settings / Other / Save custom content option to save your favorite locations, custom fractal types, paint modes and palettes to a text file.
Once the file is ready, you will be asked where to save it. We recommend selecting Save to Drive to share the file with another device.
Then use the Settings / Other / Restore custom content option on another device to load the content from the file.
WARNING: the file content is not merged with your current custom content. Instead, it just replaces is.
NOTE: transferring the thumbnail images for your custom paint modes is not yet supported. The app's settings are also not transferred.
