Hello

I want to draw grid lines on a 3D plane, like you can see in most 3D modeler software. See this image:

What I'm thinking while I write this post:

-Create an image of a square with a white border
-Apply this image as texture to the plane in repeat

Or is there a better method to draw on 3D objects?

If this would be a good method, how do I measure the image? I want the grid lines to be 1 AppGameKit unit apart. How many pixels should my square be to accomplish this?

Thanks!

I'd do this as we don't currently have a Draw3DLine command yet. (Or even a wireframe command)

Create a plain 10x10 units, scale the image 10x10. There you go.

Signature removed by mod because it's larger than 600x120... please resize and try again.

if you will use drawline as help you can use GetScreenXFrom3D GetScreenYFrom3D but it will be more an overlay.
