I've posted this question in gis.stackexchange earlier but I'm not sure if that was in fact the right place to post it, since this is more of a coding/technical question. I'm attempting to draw a character in 3D Space. However, nothing seems to place the character on the screen.
Below is what I'm attempting to do in code: Anyone have any ideas? I'm beyond lost at this point and will admit that I know next to nothing about openGL
double outX = 0;
double outY = 0;
double outZ = 0;
//This allows ArcGlobe to convert a lat lon into a 3D Coordinate system between -1 and 1
myGlobeViewUtil.GeographictoGeocentric(0 ,0 ,0 , out outX , out outY , out outZ);
Font font = new Font("Courier New" , 32.0f , FontStyle.Bold);
uint dbase = GL.genLists(256);
wglUseFontBitmaps(this.Handle, 32, 256 , dbase);
GL.glLoadIdentity();
GL.glTranslatef(0.0f , 0.0f , -1.0f);
GL.glColor3f(1.0f , 0.0f , 0.0f);
GL.glRasterPos3d(geoX , geoY , geoZ);
GLPrint("TEST");
private void GLPrint(string inText)
{
GL.glPushAttrib(GL.GL_开发者_如何转开发LIST_BIT);
GL.glListBase(dbase -32);
GL.glCallLists(text.length , GL.GL_UNSIGNED_SHORT , text);
GL.glPopattrib();
}
EDIT: Due to pre-existing requirements I must use CsGL http://csgl.sourceforge.net/
Finally now it works!
public class OurView : OpenGLControl
{
readonly GDITextureFont _myGDITextureFont = new GDITextureFont(new Font("Courier New", 32.0f, FontStyle.Bold));
public override void glDraw()
{
OpenGL.glClear(OpenGL.GL_COLOR_BUFFER_BIT | OpenGL.GL_DEPTH_BUFFER_BIT); // Clear Screen And Depth Buffer
OpenGL.glLoadIdentity();
OpenGL.glTranslated(0, 0, -1000); // !!!
OpenGL.glRotated(35, 1, 1.2, 0.2);
OpenGL.glScaled(2, 2, 2);
OpenGL.glPushMatrix();
OpenGL.glColor3f(1, 1, 0);
OpenGL.glTranslated(-20, -10, 100);
_myGDITextureFont.DrawString("Working!");
OpenGL.glPopMatrix();
}
protected override void OnSizeChanged(EventArgs e)
{
base.OnSizeChanged(e);
Size s = Size;
double aspect_ratio = (double)s.Width / (double)s.Height;
OpenGL.glMatrixMode(GL.GL_PROJECTION);
OpenGL.glLoadIdentity();
// special frustum, to have nice font display
OpenGL.glFrustum(-s.Width, s.Width, -s.Height, s.Height, 700, 1300);
OpenGL.glMatrixMode(OpenGL.GL_MODELVIEW);
OpenGL.glLoadIdentity();
}
}
