![]() Fortunately, today we have cameras with very high resolutions that allow us to create normal maps with a detail difficult to achieve in geometric scanning techniques.Īll normal maps in this pack have been obtained using photometric stereo, which provides a very realistic result compared to other 3D models of plants where the normal map is extracted from the diffuse, which produces a very unrealistic result.Īs can be seen in the following comparison, the scanned normal map is one of the most important maps when creating realistic vegetation since, if done correctly, it allows a large amount of detail that breaks up the reflections, generating a result practically indistinguishable from the reference photograph. For these cases, a technique called “Photometric Stereo” is usually more interesting, because the amount of details It no longer depends on the number of triangles, but on the number of pixels of our camera. ![]() However, these 2 techniques, as they are methods designed to create a triangular geometry in 3D, have the limitation of triangles size. Ferns have a reputation for being tough to grow, but as long as they. Bird’s nest ferns are a good choice for shady spots, as well as any of the footed ferns, such as rabbit’s foot fern. Mine are all in an east window or back a few feet from one, Steinkopf says. ![]() There are different methods to scan geometry such as photogrammetry or laser scanning. Ferns, in general, can tolerate low light situations.
