| - | The Derivative maps within Knald are generated one the fly from the [[height_maps_knald|Height maps]] provided by [[the_integrator_knald|The Integrator]]. They are adjustable in real time in terms of intensity via the [[the_main_tab_knald#general|Bump Scale]] slider in the [[the_main_tab_knald|Main Tab]]. | ||

| - | ===== What are Derivative Maps? ===== | ||
| - | |||
| - | Derivative Maps are a recent method of bump mapping that does not use tangent spaces. This has numerous advantages over traditional normal map based workflows((http://mmikkelsen3d.blogspot.co.uk/2011/07/derivative-maps.html))((http://mmikkelsen3d.blogspot.co.uk/2011/11/derivative-maps-in-xnormal.html)). | ||

| - | These are as follows: | ||
| - | * Reduces foot-print | ||
| - | * Is much better suited for synthesized surfaces/tessellation | ||
| - | * Does not distinguish between regular geometry and tessellation. | ||
| - | * Works with per pixel generated texture coordinates such as [[http://www.slideshare.net/icastano/cascades-demo-secrets|Tri-Planar Texturing]]. | ||
| - | * No issues regarding multiple standards for implementation of tangent space generation. | ||
| - | * Mirroring trivially works. | ||
| - | * No need to recalculate tangent spaces on meshes with complex geometric deformations. | ||
| - | * Better visually during texture magnification. | ||
