begin

open override fun begin(type: Int)(source)

The begin callback method is invoked like javax.media.opengl.GL.glBegin to indicate the start of a (triangle) primitive. The method takes a single argument of type int. If the GLU_TESS_BOUNDARY_ONLY property is set to GL_FALSE, then the argument is set to either GL_TRIANGLE_FAN, GL_TRIANGLE_STRIP, or GL_TRIANGLES. If the GLU_TESS_BOUNDARY_ONLY property is set to GL_TRUE, then the argument will be set to GL_LINE_LOOP.

Parameters

type

Specifics the type of begin/end pair being defined. The following values are valid: GL_TRIANGLE_FAN, GL_TRIANGLE_STRIP, GL_TRIANGLES or GL_LINE_LOOP.
