Added new _STRCMP and _STRICMP commands for quick string comparisons. Cleaned up QB64 to finish removing the QUI (quick user insert) code and folders. Altered UCASE and LCASE routines to be faster in some situations for us.

{{PageDescription}}
|
|
|
|
'''_glCullFace''' specifies whether front- or back-facing facets are culled (as specified by ''mode'') when facet culling is enabled. Facet culling is initially disabled. To enable and disable facet culling, call the {{KW|_glEnable}} and {{KW|_glDisable}} commands with the argument {{KW|_GL_CULL_FACE}}. Facets include triangles, quadrilaterals, polygons, and rectangles.
|
|
|
|
{{KW|_glFrontFace}} specifies which of the clockwise and counterclockwise facets are front-facing and back-facing. See {{KW|_glFrontFace}}.
|
|
|
|
|
|
{{PageNotes}}
|
|
|
|
If {{Parameter|mode}} is {{KW|_GL_FRONT_AND_BACK}}, no facets are drawn, but other primitives such as points and lines are drawn.
|
|
|
|
|
|
{{PageErrors}}
|
|
|
|
{{KW|_GL_INVALID_ENUM}} is generated if {{Parameter|mode}} is not an accepted value.
