- Edge Shinethrough
Edge shinethrough occurs when faces are pushed back so far that an edge that should be hidden appears either partially or completely. In the figure below, a hidden interior edge shines through partially at the top of a pyramid when the left front face of the pyramid should have hidden it.
You can address this issue by updating the face displacement option in HC_Set_Rendering_Options as well as following the HOOPS camera set up guidelines.
- Edge Stitching
- When both the edges and faces of a polygon are visible, they are almost exactly the same distance form the camera. Due to z-buffer precision problems, an edge can appear dashed as it pops in and out from behind one or more faces. In the figure below, three different edges in a pyramind appear as dashed lines when they should appear solid. You can address this issue by updating the face displacement option in HC_Set_Rendering_Options as well as following the HOOPS camera set up guidelines.
