CS297 Graphics with Java and OpenGL

CS297 Graphics with Java and OpenGL. State Management and Drawing Primative Geometric Objects. Specifying Vertices. A vertex is a point in 3D space, that can be specified as either a pair, triple or quadruple of values. E.G. valid definitions for vertices : gl.glVertex2f(-0.5f, -0.5f);

Drawing Geometric Objects

Drawing Geometric Objects. Drawing Primitives. OpenGL sets three types of drawing primitives Points Lines Polygons, e.g, traingles All primitives are represented in terms of vertices that define the positions of the points themselves or the ends of line segments or the corners of polygons.

Drawing Primitives

Drawing Primitives. Foreward. This presentation shows how some primitive shapes may be drawn using openTK ( openGL ) This is not the only approach to draw these primitives, but may be the most common. DrawLine (). private void DrawLine () { // Clear screen to background color.
