Member Function Documentation

void create (  ulong    width, ulong    height )

Parameters: _width  width of the landscape _height  height Definition at line 88 of file r_landscape.cpp.

void create_from_image (  image_c *    img )

Parameters: img  image to use Definition at line 161 of file r_landscape.cpp.

void create_from_raw (  uchar *    raw, ulong    width, ulong    height )

Parameters: raw  pointer to an unsigned char array width  x dimension of array height  and y Definition at line 197 of file r_landscape.cpp.

void create_from_texture (  sshort    tex )

Parameters: tex  texture index to use Definition at line 138 of file r_landscape.cpp. References SafeDelete.

void prelight (    )

This function uses the lights in gv.lights[] to apply lighting to the terrain. The lights' position is interpreted as a directionial vector where the light is coming from.
