Wittevrongel was born in Blankenberge, Belgium, and got his education in Ghent where he combined his studies at the Royal Academy of Fine Arts (1953-1956) with a teacher training plastic arts in the State School (1954-1956) under the guidance of Octave Landuyt.
From 1956 up to 1971 he worked as a teacher plastic arts at the State School in Ghent. Consequently he was professor etching, drawing and lithography at the Royal Academy for Fine Arts in Ghent until 1997, where he got the title of honorary professor since then.
In 1954, Roger Wittevrongel made his debut in the atmosphere of Octave Landuyt, yet more in an abstract way, with work around destruction, devastation and animal heads. Around 1964 he started to paint more figuratively, mainly architectural compositions decorated with vegetable elements and female nudes surrounded by all kinds of attributes (for example painting and drawing tools). Around 1970 he comes to a hyperrealistic style with an absolute accuracy in the reproduction of what the eye could see. However, he continued to evolve within this style and concentrated on trivial subjects, which he also depicted with the greatest precision. The subjects themselves - interiors, fragments of architecture and female characters, are treated as still-lives, which gives them an abstract quality. These works in particular raise questions concerning man's relationship with visible reality. Here the astonishment is less evoked by the technical virtuosity but more by the question of the meaning of existence.
