draw circle and direct x
Author
I want to draw a very simple circle using directx 9.I have tried a few things I have found online but no luck. I also need to know if the following command is correct.
D3DXVector3 pos (float x, float y, 0);
I am still learning directx 9.
I don't think you've looked hard enough. :-P

I need to know how to draw a circle to the screen using direct x9. I found some code that might work.
However I need to know the direct x command that actually prints to the screeen.
#define PI 3.14159f float radius = 20.0f; float smoothness = 0.05f; float center_x = 400.0f; float center_y = 300.0f; for(float angle = 0.0f; angle <= (2.0f * PI); angle += smoothness) { float x = center_x + (radius* (float) sin (angle)); float y = center_y + (radius* (float) cos (angle)); }However I need to know the direct x command that actually prints to the screeen.
See this tutorial, it explains how to draw the vertices you create for your circle: Tutorial 2: Rendering Vertices.
