IMPA doctoral student is awarded at SIBGRAPI 2025
IMPA doctoral student Daniel Perazzo was recognized with the award for best master’s dissertation at SIBGRAPI 2025 – the largest computer graphics and computer vision event in Latin America, held in Salvador (BA), at Senai Cimatec. The award-winning work, entitled “Study on Gaussian Splatting and Neural Fields”, proposes advances in one of the most innovative and transformative techniques in the field, Gaussian Splatting.
In addition to the award, Perazzo also had an accepted tutorial on 3D Gaussian Splatting. The presentation brought together students, professors and experts from all over the country. “It was an incredible experience. The auditorium had professors from various institutions in the country. It’s pretty cool to explain a technique even to university professors. It was very gratifying.”
During the presentation, the doctoral student highlighted the mathematical foundations that support Gaussian Splatting – one of the differentials of his research. “I showed how it is possible to derive Gaussian Splatting from mathematical principles — something that is not normally addressed in works in the area,” he explained.
The award-winning dissertation investigates improvements on the state of the art in the field of Gaussian Splatting, a technology that has been revolutionizing computer graphics and computer vision. The technique makes it possible to reconstruct three-dimensional objects from multiple 2D images, representing the scene as a set of “Gaussian” — small ellipsoidal shapes that, combined, result in highly realistic 3D representations. Its applications range from virtual and augmented reality to digital gaming, medicine, and entertainment.
“It’s amazing how much this technique is impacting the field. It allows you to create 3D reconstructions so photorealistic that it is hard to believe that they are not real objects”, highlighted the doctoral student.
Perrazzo’s research was supervised by researchers Luiz Velho and Tiago Novello, from Visgraf (IMPA’s Computer Graphics Laboratory). Part of the results of the dissertation have already been explored in recent projects of the center, such as the development of 3D representations in interactive environments.
The recognition at SIBGRAPI 2025 marks Perazzo’s second award at the event. In 2022, when he was still an undergraduate student (UFPE), he won the award for best article in computer graphics, also with a work developed in collaboration with Visgraf.
“I was very happy with this new recognition. It’s great to see a job, in which we dedicate ourselves so much, be valued by such an important community. It was also an opportunity to meet incredible researchers and open up new possibilities for collaboration,” he concluded.
