In file include/csengine/polytext.h:

class csPolyTexture

This class represents a lighted texture for a polygon

Public Fields
static float cfg_cosinus_factor: Option variable: control how much the angle of the light with the polygon it hits affects the final light value
static bool do_accurate_things: Option variable: do accurate lighting of things. This is much slower however.
float Fmin_u: fp bounding box (0..1 texture space)
static bool subtex_dynlight: If the sub-texture optimization is enabled (subtex_size != 0) then this option gives an additional optimization
static int subtex_size: The size of the sub-textures

Public Methods
int CountCleanSubtextures(): Return the number of clean sub-textures
int CountDirtySubtextures(): Return the number of dirty sub-textures
void CreateBoundingTextureBox(): Calculate the bounding box in (u,v) space for the lighted texture
void CreateDirtyMatrix(): Create the dirty matrix if needed
csPolyTexture()

csLightMap* GetLightMap()
int GetMipmapLevel()
int GetMipmapSize(): Get the mipmap size used for this texture.
int GetOrigWidth()
int GetShiftU()
ITextureHandle* GetTextureHandle()
int GetWidth(): Get width of lighted texture (power of 2).
void InitLightMaps(): Initialize the lightmaps
void MakeAllDirty(): Make the dirty matrix completely dirty
void MakeDirtyDynamicLights()
bool RecalcDynamicLights(): Recalculate all pseudo and real dynamic lights if the texture is dirty
void SetMipmapLevel(int mm)

virtual ~csPolyTexture()

Private Fields
int and_u
int dirty_cnt: Number of dirty sub-textures (if 0 whole texture is clean and in the cache
int dirty_h: Height of dirty matrix.
UByte* dirty_matrix: Dirty matrix used in combination with the sub-texture optimization
int dirty_size: Size of dirty matrix (dirty_w*dirty_h).
int dirty_w: Width of dirty matrix.
int du
int dv
bool dyn_dirty: If true, dynamic lighting needs to be recalculated.
float fdu
float fdv
int h: Height of lighted texture.
int Imin_u: Bounding box of corresponding polygon in 2D texture space
csLightMap* lm: LightMap.
int mipmap_level: The mipmap level (0..3) that this PolyTexture is used for.
int mipmap_shift: Mipmap shift corresponding to the mipmap_size above.
int mipmap_size: Mipmap size to use for lightmap boxes: 16, 8, 4, or 2.
csPolygon3D* polygon: The corresponding polygon.
int shf_u
int size: Size including vertical margins (note: size is in pixels, multiply this value by the real number of bytes for every pixel to get the real size)
void* tcache_data: Private texture cache data.
ITextureHandle* txt_handle: The corresponding unlighted texture.
int w: Width of lighted texture ('w' is a power of 2).
int w_orig: Original width (not a power of 2) (w_orig <= w).
