Geometry Nodes
The first group collects all geometry data from the scene, converting object coordinates into normalized camera space to ensure consistent filter behavior, regardless of object scale. This normalization process ensures that objects of different sizes and distances are treated equally, allowing for consistent visual effects. This group also stores both the point position and point normals as PositionX and NormalX because this is the only time they will be in their original location. These will be used quite often in future operations.
The Flatten in Camera Space operation works by determining the direction from each point on the object to the camera and assessing how well each point aligns with the camera's view. Points are then adjusted based on this alignment, effectively flattening them towards the camera within a normalized range of 0.1 to 0.25 meters. This step ensures that only visible parts are processed, improving efficiency and preventing distortions, making the filter dependable across various scenes.
This formula flattens a point towards the camera. It calculates the direction from the camera to the point, aligns it with the camera's view, scales it by a flatten offset and then adjusts the point’s position accordingly. The result ensures the point is properly aligned in the camera's view for rendering.
By combining these processes, the system reduces computational load, ensures accurate transformations, and maintains visual consistency for both small details and larger elements.
