Fuzzy Objects

Question

Is there a possible solution to how i can fix the fuzziness of my output object in City Engine? Is there something to do with how i write my CGA rule? Thanks!

Hi Derrik, in 3D rendering the phenomenon creating those fuzzy surfaces is called Z-fighting. It occurs when two or more primitives have very similar distances to the camera. This would cause them to have near-similar or identical values in the z-buffer, which keeps track of depth. This then means that when a specific pixel is being rendered, it is nearly random which one of the two primitives gets drawn in that pixel because the z-buffer cannot distinguish precisely which one is farther from the other. To avoid this from happening in your CGA code, it is important to add NIL to the leaf shapes that are not needed to be drawn. e.g.: Generate --> Paint Report Paint --> color("#FF0000") Report --> report("facadearea", geometry.area()) NIL‍‍‍‍‍‍‍
