Detailed Description
Encapsulates an image that will be interpreted as a heightmap.
Constructor & Destructor Documentation
◆ ImageHeightmap()
ImageHeightmap | ( | ) |
Constructor.
- Parameters
-
[in] _filename the path to the image
Member Function Documentation
◆ Filename()
std::string Filename | ( | ) | const |
Get the full filename of the image.
- Returns
- The filename used to load the image
◆ FillHeightMap()
|
virtual |
Create a lookup table of the terrain's height.
- Parameters
-
[in] _subsampling Multiplier used to increase the resolution. Ex: A subsampling of 2 in a terrain of 129x129 means that the height vector will be 257 * 257. [in] _vertSize Number of points per row. [in] _size Real dimmensions of the terrain. [in] _scale Vector3 used to scale the height. [in] _flipY If true, it inverts the order in which the vector is filled. [out] _heights Vector containing the terrain heights.
Implements HeightmapData.

◆ Load()
int Load | ( | const std::string & | _filename = "" | ) |

- Parameters
-
[in] _filename the path to the image file.
- Returns
- True when the operation succeeds to open a file.
◆ MaxElevation()
|
virtual |
Get the maximum terrain's elevation.
- Returns
- The maximum terrain's elevation.
