Member Function Documentation

void create_from_plane (  const plane_t *    p )

Initializes this face using a plane_t. Parameters: p  Plane to use Definition at line 68 of file x_brush.cpp. References SafeArrayDelete. Referenced by brush_c::add_plane().

bool cut (  const plane_t *    p )

Cuts this face in two pieces using p as the dividing plane. Returns true if degenerated so you know that you can be removed Parameters: p  Dividing plane Definition at line 146 of file x_brush.cpp. References _sgn(), vec2_c::copy(), vec3_c::copy(), vertex_s::diffuse, vec2_c::linear(), vertex_s::normal, plane_line_intersect(), plane_pointdist(), SafeArrayDelete, vertex_s::uv, vec3_t, vertex_copy(), and vertex_s::xyz. Referenced by brush_c::add_plane().

void get_edge (  ulong    num, edge_t    out )

Gets edge num and stores it in out. An edge is the connection of two vertices on this face. There are as many edges as vertices. If num is larger than the vertex count it wraps around. Parameters: num  Index of edge out  Where to store it Definition at line 224 of file x_brush.cpp. References edge_t. Referenced by brush_c::find_edges().

vec3_c get_normal (    )  [inline]

Returns the normal vector of the plane this face lies in. Definition at line 168 of file brush.h. References plane_s::n, and plane.

const plane_t * get_plane (    )  [inline]

Returns a pointer to the plane of the face. Definition at line 175 of file brush.h. References plane. Referenced by brush_c::add_plane().

const struct shader_s * get_shader (    )  [inline]

Returns the shader that is used to draw the face Definition at line 189 of file brush.h.

void get_vertex (  ulong    num, vertex_t *    out )

Gets vertex num and stores it in out. If num is larger than the vertex count it wraps around. Parameters: num  Index of vertex out  Where to store it Definition at line 210 of file x_brush.cpp. References vertex_copy().

ulong get_vertex_count (    )  [inline]

Returns the number of vertices in this face Definition at line 156 of file brush.h. References vertexcount. Referenced by brush_c::find_edges().

const vertex_t * get_vertices (    )  [inline]

Returns a pointer to the vertices of this face. Definition at line 162 of file brush.h. References vertices.

void set_shader (  const struct shader_s *    _shader )  [inline]

Sets the shader to draw this face with. Parameters: _shader  shader to use Definition at line 181 of file brush.h. References shader. Referenced by brush_c::add_plane(), brush_c::set_face_shader(), and brush_c::set_shader().

void set_tex_params (  const vec2_t    scale, const vec2_t    offset, float    rot )

Sets the texture parameters scale, offset and rotation. Parameters: _scale  scale _offset  offset rot  rotation angle Definition at line 238 of file x_brush.cpp. References vec2_t.
