Comparison
| Plug-In Texture2HeightMap | HLSLobject Texture2HeightMap | |
| expected call frequency |
occasional |
every frame |
| typial Application Scenario | Terrain generation, collision access | Dynamic generated objects, e.g. Audio Generated Landscape, Video |
| Underlying Geometry | Plane, uniform grid | Plane,Sphere, or other, uniformity is not a prerequisite |
| Vertex count relies on |
Texture size |
pre-build 3D specimen |
| Size limits | 2 squared, tested with resolution up to 2048 x 2048 | tested with XXXXXXXX |
| Persistence | yes, 3D ObjectData can be saved and copied | no |
| Collision detection |
yes |
no |
| Additional features | RGB channel weight processing | Variant: Normal Map |
| Floating point texture support (HDR) | yes | yes |
Float Textures, HDR
The following example allows to compare LDR with HDR textures. The texture used for height mapping is either HDR or a drived LDR version. The terrain is visualized with the LDR version.
LDR low diynamics and clipping
HDR more details, no limits
Compound Terrain
Compound Terrain using 3 seamles tile textures, negative weight applied, result is a single 3DObject
Grid Resolution
| Wireframe 64 x 64 |
 |
| Wireframe 256 x 256 |
 |
| Wireframe with 773 x 773 vertices |
