What’s the easiest way to draw filled triangle?..An Image gif is not so good, since the size & direction may vary. Using a cobra board & LCD.
Why double post?
I checked out that PDF in the original response … and it made no sense to me 
I read it and re-read it, and it was still difficult for me. :-[
Perhaps the Hoyt felt the same way … ?
Multiple threads with the same question are confusing. I don’t think there is an easy way of doing this. Otherwise we would’ve had it already. ;D
Look for Graphics Gems books. These books cover a lot of algorithms.
Look at DrawingContext.DrawPolygon.
So there is no way to generate a simple shape (red triangle)? What kind of graphics support is that?
I was not looking to invent an algorithm, just use the tools provided.
I am sorry, I have misled you. Of course you can use DrawPolygon (as rocketbob indicated above) for that.
Bitmap _LCD = new Bitmap(SystemMetrics.ScreenWidth, SystemMetrics.ScreenHeight);
Brush brush = new SolidColorBrush(Colors.Blue);
Pen pen = new Pen(Colors.White);
int[] triangle = new int[] { 0, SystemMetrics.ScreenHeight / 2, SystemMetrics.ScreenWidth-1, 0, SystemMetrics.ScreenWidth-1, SystemMetrics.ScreenHeight-1 };
...
//Draw a filled triangle
DrawingContext context = new DrawingContext(_LCD);
context.DrawPolygon(brush, pen, triangle);
...
I didn’t know this exists in NETMF. Learned something new today 
Yeah, that class has eluded me too.
By the way if anybody’s interested the triangle example above is used with Gus’ scope class from:
