| ) |
Adds a tile for generating the texture map. Tiles should be added from the lowest to the highest tile.
| filename | the filename of the tile | |
| hundredPercentAt | the value where the tiel does have hundred percent |
| GLvoid ES3D::Terrainf::disableROAMf | ( | GLvoid | ) |
Disables ROAM for this terrain

Enables / disables light for the terrain
| mode | mode, if light should be turned of or not |
| GLvoid ES3D::Terrainf::enableROAMf | ( | GLuint | minDetail, | |
| GLuint | maxDetail | |||
| ) |
Enables ROAM for this terrain

| xzstep | the step between each xy vertex in world space | |
| ystep | the step/scaling of the height |
| ES3Denum ES3D::Terrainf::loadTextureMapf | ( | const char *const | filename | ) |
Loads the texture. Former texture are cleaned up automatically
| filename | the filename of the texture |
| ES3Denum ES3D::Terrainf::prepareGeneratedTextureMapf | ( | GLuint | width, | |
| GLuint | numberTiles | |||
| ) |
Prepares the generation of the texture map. Former texture are cleaned up automatically
