I'm currently trying to get the Newton Physics Engine to work with my game. I'd like to debug the collision objects.

I'm not sure how to draw 3d lines, and I didn't see any commands for this.

Any ideas? Thanks!

Wow, Lilith.

DirectX has some stuff for this. Look up the line drawing interface and how to get the DarkGDK rendering device.

Ok, I know I can get the device using dbGetDirect3DDevice(). However, I really not a C++ programmer . I know I can draw lines using DrawPrimitive(), but I really have no idea how. I looked up the line drawing interface, but all I found was LPD3DXLINE. I'm not sure how to use it to draw 3d lines.

Any ideas?

There's your starting point.

Setting it up:


Then in your loop, you just do


Don't forget to

How did you get it working? I'm somewhat stuck on this. At least as far as "finding a quick solution" goes...

Here is how I do it:



But be aware that this is very inefficient (I'm re-creating and deleting the LPD3DXLINE each call!).
Maybe you can figure out how to improve it on your own.
At least this is good enough (for me) to draw a quick 3D line for debugging purposes...

Now the plot thickens, the fps decreases, and the awesomeness goes through the roof.

Thanks a lot!

I need it for pretty much the same purpose, so I think it'll be perfect for now.
