XGraphics Class |
OpenGL 라이브러리에 대한 Wrapper클래스를 정의한다.
이 클래스는 각종 뷰 컨트롤(ImageView, PlanetView등)에서 사용자가 객체를 직접 그리거나 처리하는데 사용된다.

Example
RenderLayer 중 하나인 NXImageLayerGPU의 OnRender 이벤트 함수를 추가하여 XGraphics를 이용해 OpenGL 문법으로 폴리라인으로 그리는 예제
C#
private bool nxImageLayerGPU1_OnRender(NXImageLayerGPU sender, NXImageViewDrawArgs DrawArgs) { // Draw cross mark at specific position. XGraphics g = DrawArgs.Graphics; XVertex3d vPos = new XVertex3d(127.0, 37.0, 0); // Lon : 127.0, Lat : 36.0 double nOff = DrawArgs.PixelSize * 10; g.glColor3d(1, 0, 0); g.glBegin(XGraphics.GL_LINES); g.glVertex3d(vPos.x - nOff, vPos.y, vPos.z); g.glVertex3d(vPos.x + nOff, vPos.y, vPos.z); g.glVertex3d(vPos.x, vPos.y - nOff, vPos.z); g.glVertex3d(vPos.x, vPos.y + nOff, vPos.z); g.glEnd(); DrawArgs.Invalidate(); return default(bool); }
