Macro Definition Documentation

◆ UV_ASPECT

#define UV_ASPECT (   l,
  r_uv 
)    uv_aspect(l, aspect, cd_loop_uv_offset, r_uv)

Typically we avoid hiding arguments, make this an exception since it reads poorly with so many repeated arguments.

◆ BM_edge_uv_share_vert_check()

bool BM_edge_uv_share_vert_check ( BMEdge e,
BMLoop l_a,
BMLoop l_b,
int  cd_loop_uv_offset 
)

Check if two loops that share a vertex also have the same UV coordinates.

◆ BM_face_uv_calc_center_median()

void BM_face_uv_calc_center_median ( const BMFace f,
const int  cd_loop_uv_offset,

◆ BM_face_uv_calc_center_median_weighted()

void BM_face_uv_calc_center_median_weighted ( const BMFace f,
const float  aspect[2],
int  cd_loop_uv_offset,
float  r_cent[2] 
)

Computes the UV center of a face, using the mean average weighted by edge length.

See BM_face_calc_center_median_weighted for matching spatial functionality.

Parameters
aspectCalculate the center scaling by these values, and finally dividing. Since correct weighting depends on having the correct aspect.

◆ BM_face_uv_calc_cross()

float BM_face_uv_calc_cross ( const BMFace f,
int  cd_loop_uv_offset
