As our electronic devices are becoming more sophisticated, the needs to capture the environment in a digital form are growing. In addition to the ways of automatically analysing the data, the visualization of the respective data is also important for the user. Therefore, an efficient algorithm that plots a convincing reconstruction of the scanned model in real time is essential. This thesis describes five approaches to rendering point clouds. Some of the approaches are simple and only use the functionality of graphics cards, while others try to improve the rendering by interpolating colours. Seven different implementations in the Rendercore framework are derived from the approaches. A proposal for a new algorithm, which tries to eliminate some of the shortcomings of the others, is also described. Rendering time is measured for all eight algorithms, and the result is compared with a mesh reconstruction of the model. In qualitative terms, the proposed algorithm achieves the best results.
