Function Documentation

void GLAPIENTRY _mesa_CullFace (  GLenum    mode )

Specify whether to cull front- or back-facing facets. Parameters: mode  culling mode. See also: glCullFace(). Verifies the parameter and updates gl_polygon_attrib::CullFaceMode. On change, flushes the vertices and notifies the driver via the dd_function_table::CullFace callback.

void GLAPIENTRY _mesa_FrontFace (  GLenum    mode )

Define front- and back-facing. Parameters: mode  orientation of front-facing polygons. See also: glFrontFace(). Verifies the parameter and updates gl_polygon_attrib::FrontFace. On change flushes the vertices and notifies the driver via the dd_function_table::FrontFace callback.

void GLAPIENTRY _mesa_GetPolygonStipple (  GLubyte *    mask )

void _mesa_init_polygon (  GLcontext *    ctx )

Initialize the context polygon state. Parameters: ctx  GL context. Initializes __GLcontextRec::Polygon and __GLcontextRec::PolygonStipple attribute groups.

void GLAPIENTRY _mesa_PolygonMode (  GLenum    face, GLenum    mode )

Set the polygon rasterization mode. Parameters: face  the polygons which mode applies to. mode  how polygons should be rasterized. See also: glPolygonMode(). Verifies the parameters and updates gl_polygon_attrib::FrontMode and gl_polygon_attrib::BackMode. On change flushes the vertices and notifies the driver via the dd_function_table::PolygonMode callback.

void GLAPIENTRY _mesa_PolygonOffset (  GLfloat    factor, GLfloat    units )

void GLAPIENTRY _mesa_PolygonOffsetEXT (  GLfloat    factor, GLfloat    bias )

void GLAPIENTRY _mesa_PolygonStipple (  const GLubyte *    mask )

void _mesa_update_polygon (  GLcontext *    ctx )
