Dynamic transitioning between visual user interface elements on a display

A non-transitory computer readable medium having stored thereon a set of computer readable instructions that, when executed by at least one processor, cause an apparatus comprising a User Interface, UI:

• generate or receive particles, wherein each particle has a first position associated with a first shape, and storing the first positions as current positions;
• determine a second shape, wherein the second shape forms a first target shape for a first transition from the first shape, and a first target time for the first transition;
• generate and store first target positions of the particles associated with the second shape;
• compare the first target time to a current time;
• responsive to the first target time being larger than the current time, determine intermediate positions of the particles, based on the current positions and the first target positions of the particles, wherein the intermediate positions are closer to the target positions than the current positions;
• update the user interface by using the intermediate positions of the particles to provide a graphical output on a display;
• and
• store the intermediate positions as the current positions.

An apparatus comprising at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to:

• generate or receive particles, wherein each particle has a first position associated with a first shape, and storing the first positions as current positions;
• determine a second shape, wherein the second shape forms a first target shape for a first transition from the first shape, and a first target time for the first transition;
• generate and storing first target positions of the particles associated with the second shape;
• compare the first target time to a current time;
• responsive to the first target time being larger than the current time, determine intermediate positions of the particles, based on the current positions and the first target positions of the particles, wherein the intermediate positions are closer to the target positions than the current positions;
• update the user interface by using the intermediate positions of the particles to provide a graphical output on a display;
• and
• store the intermediate positions as the current positions.
