Function Documentation

void GLAPIENTRY _mesa_init_line (  GLcontext *    ctx )

Initialize the context line state. Parameters: ctx  GL context. Initializes __GLcontextRec::Line and line related constants in __GLcontextRec::Const.

void GLAPIENTRY _mesa_LineStipple (  GLint    factor, GLushort    pattern )

Set the line stipple pattern. Parameters: factor  pattern scale factor. pattern  bit pattern. See also: glLineStipple(). Updates gl_line_attrib::StippleFactor and gl_line_attrib::StipplePattern. On change flushes the vertices and notifies the driver via the dd_function_table::LineStipple callback.

void GLAPIENTRY _mesa_LineWidth (  GLfloat    width )

Set the line width. Parameters: width  line width in pixels. See also: glLineWidth(). Verifies the parameter and updates gl_line_attrib::Width. On a change, flushes the vertices, updates the clamped line width and marks the DD_LINE_WIDTH flag in __GLcontextRec::_TriangleCaps for the drivers if the width is different from one. Notifies the driver via the dd_function_table::LineWidth callback.
