Hi!
I tried to draw a triangle in red and some characters in blue, but failed.
In the code, I tried in 2 places to set the color of characters to be blue, but the actual displayed color is always the same as the triangle.
Can you tell me how to fix it?
Thank you!
following is the code:
FormCreate
{attmpt to define the character bitmap color}
glColor3f(0,0,1);
wglUseFontBitmaps(Form1.Canvas.Handle, 48, 10, 1);
wglUseFontBitmaps(Form1.Canvas.Handle, 65, 26, 11);
MyDraw routine
procedure TForm1.MyDraw;
begin
glClearColor(0,1,0,0);
glClear(GL_COLOR_BUFFER_BIT or GL_DEPTH_BUFFER_BIT);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity;
gluLookAt(0,0,0, 0,0,1, 0,1,0);
glTranslate(Xshift,Yshift,0);
glScalef(Xscale,Yscale,Zscale);//draw graph
glColor3f(1,0,0);
glBegin(GL_LINE_LOOP);
glVertex3f(0, 0.4,1);
glVertex3f(0.5,-0.5,1);
glVertex3f(-0.5,0.3,1);
glEnd;//display the characters
glRasterPos3f(0,0,2);
{attmpt to change color}
glColor3f(0,0,1);
glCallList(12);
glCallList(13);SwapBuffers(Canvas.Handle);
end;
