India's Ambassador to the UN Syed Akbaruddin also tweeted about it.
"Yoga set to light up UN. Sneak peek of Yoga posture projections on iconic UN Headquarters building in New York on IDY 2016," he said.
The image projected onto the UN building shows a woman doing the 'Parvatasana' or the 'inverted V' posture. The words 'International Day of Yoga' are projected below the image.
India's Permanent Mission to the UN in association with the UN Department of Public Information will commemorate the day on June 21 at the world body's headquarters.
The event will be attended by General Assembly President Morgens Lykketoft, Under-Secretary-General for Communications and Public Information Cristina Gallach and Isha Foundation founder and spiritual leader Jaggi Sadhguru, who will lead a simple Yoga practice.
The event will also include a musical incantation on yoga and renowned British singer Tanya Wells will recite Sanskrit shlokas.
Akbaruddin had said earlier this week that this year's celebration of the International Yoga Day will lay special emphasis on enhancing awareness that yoga is a holistic approach and not just a physical activity and how it can help in achieving the Sustainable Development Goals.
Akbaruddin said a huge and diverse turnout is expected at the Yoga Day gathering at the UN Secretariat Circle, with participants from 100 nationalities having registered for the event so far.
Ambassadors and diplomats from various countries will also share their own experiences of how Yoga has influenced their life styles.
In a precursor to Yoga Day, the Indian mission will host 'Conversation with Yoga Masters' that will "seek to enrich our collective understanding of the unique features of Yoga and its role for the achievement of SDGs." The spiritual leader will participate in the event.
Indian peacekeepers are also practicing to observe the Yoga Day in the 13 peacekeeping operations where they are currently deployed, including in South Sudan, Congo and Lebanon, "tangibly demonstrating the role of Yoga in promoting peace and harmony," the Indian envoy had said.
A host of other events are being organised by the Indian Consulate in association with the local Indian community organisations in the New York tri-state area in the run-up to the Yoga Day.
For the commemoration, the Consulate has partnered with more than 25 associations. The organisations will be hosting special Yoga sessions in schools, temples as well as at the JFK International Airport and Newark Airport.
In December 2014, the UN General Assembly had adopted a resolution with a record number of 177 co-sponsoring member states to establish the International Day of Yoga to be commentated every year on June 21.
