Visualization of inner structure of complex 3D objects based on opacity modulation

This thesis addresses problem of rendering semi-transparent objects and the enhancement by~opacity modulation to reveal object's internal structures. Illustration Buffer - algorithm solving the Order Independent Transparency (OIT) is implemented and compared to other OIT solving techniques: Depth Peeling, Dual Depth Peeling and Per Pixel Linked Lists. We focus on opacity modulation based on object's features and we apply such modulations to the Illustration Buffer while comparing the ease of use with other algorithms. Finally we test all mentioned algorithms and conclude which algorithm is better under specific circumstances.
