Lublin University of Technology has been offering computer science studies for over 25 years. From the beginning, computer graphics have played a crucial role in the studies program. The Lab3D international efforts aimed at cultural heritage 3D digitization allowed for enriching the regular introductory course of computer graphics with elements of digitized real-life heritage, without disturbing the regular didactic process, nor the scope of the course learning outcomes. Such an activity was aimed at increasing the students’ engagement in learning and fits into the contemporary trend of including real-life cases in the course of teaching. The article presents the curriculum (including the changes introduced) together with an extensive analysis of the effect of such changes on students’ achievements. In total, 3042 grades of 1522 students from the years 2018–2024 underwent statistical analysis in order to support answering placed hypotheses related to keeping the effects positive or neutral. Luckily, students’ achievements did not worsen, and in fact significantly improved. To the authors’ knowledge, such an analysis in relation to computer graphics courses has never been published before.
