Web25 de ago. de 2024 · I would like to create smooth curves using the tessellation shader. First, I tried to create Bezier curves with tessellation (patch number = 4), but if I have a line with more than 4 control points, then there are gaps at every 4 vertices.

WebFor quads we have 4 outer tessellation levels and 2 inner. Because, surprisingly :-), we have 4 edges and 2 dimensions to subdivide inside quad. If you calculate tessellation levels dynamically (e.g. based on distance from camera) care should be taken to set correct index in gl_TessLevelOuter/Inner. WebTessellation Shader. The tessellation stage can be used to render curved surfaces. This is an optional stage. The level of detail can be controlled based on the distance of the object from the camera. The tessellation stage consists itself of three stages: Control. Tessellation control in OpenGL and Vulkan; Hull shader in DirectX
