[Resolved] - Draw shape being drawn in wrong place

Hi All,

I found something weird today which looks like a bug.

I am using 14 - Game Basics - 14 - Camera Modes and I added a second camera and viewport. I wanted to draw a pyramid and an edge to show where the camera is pointing which works great. However, if I add a terrain type object to the world, the shape will be drawn there unless I am actually looking at the camera.

I have attached my draw function below, the whole source to the post and a video showing it. I also attached the tree in question because i tried the same thing with the rock model and it did not happen which i find even weirder.....

Code:

void Draw()

{

   Camera mainCam = Cam;

   Renderer(Render);

   D.text  (0, 0.9, "Press Tab to switch camera modes");

   Pyramid(.5, 2.0 ,Cam2.matrix.pos, !(Cam2.at-Cam2.matrix.pos)).draw(BLUE, false);

   Edge(Cam2.matrix.pos, Cam2.at).draw(BLUE);

   Cam2.set();

   //D.viewFov(1.309);

   Rect MiniMap = Rect((D.viewRect().max - D.viewRect().max/2.0),D.viewRect().max);

   D.viewRect(MiniMap);

   Renderer(Render);

   mainCam.set();

   D.viewRect(null);

**EDIT - Removed Bug from description **

Try put SetMatrix() on first line of Draw()

Hi Sam,

That is a good thought. I added SetMatrix() right before the draw Pyramid and that seems to have worked. I did not even think about the matrix being moved in the previous render call, nice one.

I think that resolves it. Still not too sure why it only happens with the bamboo model but hey, whatever works.

Thanks a lot!!!
