Algorithmic modeling offers a powerful way to add complex textures and geometric patterns to different surfaces. However, one common problem occurs when working with surfaces that have different UVs or texture coordinates. The UVs control how the algorithmic patterns are mapped onto the surface, leading to distorted or fragmented features when UVs differ across surfaces.
How to create continuous algorithmic features over surfaces with different UVs
Here is a technique to create continuous algorithmic features over surfaces with different UVs:
- Flatten the surface: Begin by flattening the surface to create a representation of its outline. This flattened representation will serve as the base for projecting the algorithmic features.
- Create an algorithmic feature: Generate the desired feature, such as a hexagonal grid, on an extruded surface.
- Project the feature onto the flattened surface: Project the created algorithmic feature from the extruded surface onto the flattened surface representation. This ensures the pattern is applied uniformly without the influence of differing UVs.
- Reform the surface: Use the original geometry to reform the flattened surface, bringing the projected algorithmic features along with it. This step maps the uniformly applied pattern back onto the original model.
Result
This technique creates a continuous and undistorted algorithmic feature across the entire surface, regardless of UV variations. The features are evenly dispersed to avoid bunching or distortion caused by inconsistent UVs.
Summary
This method provides a solution to a common challenge in algorithmic modeling. It enables more accurate and consistent application of complex features on diverse models.
