Member Function Documentation

static void shapes3d.utils.GL.cullFace ( PGraphics  pg, int  mode  )

static

Indicates which polygons should be discarded (culled) before they are converted to screen coordinates. The mode is either GL_FRONT, GL_BACK, or G_FRONT_AND_BACK to indicate front-facing, back-facing or all polygons. Culling can be enabled / disabled with the glEnable(boolean) or glDisable(boolean) methods.

Parameters

pg	the OpenGL drawing surface
mode	GL_TRUE or GL_FALSE

static void shapes3d.utils.GL.disable ( PGraphics  pg, int  cap  )

static

Parameters

pg	the OpenGL drawing surface
cap	capability

static void shapes3d.utils.GL.enable ( PGraphics  pg, int  cap  )

static

Parameters

pg	the OpenGL drawing surface
cap	capability

static void shapes3d.utils.GL.frontFace ( PGraphics  pg, int  mode  )

static

Controls how front-facing polygons are determined. By default, mode is GL_CCW, which corresponds to a counterclockwise orientation of the ordered vertices of a projected polygon in window coordinates. If mode is GL_CW, faces with a clockwise orientation are considered front-facing.

Parameters

pg	the OpenGL drawing surface
mode	either GL_CCW or GL_CW
