xna - 2d Ray intersection - Game Development Stack Exchange
https://gamedev.stackexchange.com/questions/11234/2d-ray-intersection
Another alternative is to use XNA's built in Ray class and BoundingBox class. Although they are typically used in 3d, often (as in this case) you can simply set their Z components to zero and utilize them in 2d as needed. It seems to me that that would achieve a dramatic simplification to your code. Share.

XNA is tracing rays…. I had this very same idea just a week ago and now someone has done it: A Raytracer written entirely in C# and running upon XNA. “Ok, I’ve got most of what I want done on the Ray Tracing project — enough at least to publish some code and do some blogging. This first article describes the overall coding structure ...

Second, build a Ray from your two positions. pos1 will be origin of the ray; pos2 - pos1 (normalized) will be the direction. You will also want to store the distance between the two points for later use. Then, just loop over each object in your pre-built list of bounding boxes and call the Intersects method of your ray.

XNA 3.0 Hybrid Ray Tracer - timjones.io
http://timjones.io/blog/archive/2008/05/15/xna-hybrid-ray-tracer
Features. Automatically switches from ray tracing to hardware rasterization when camera is moving. Loads scenes from an XML file using the XNA Content Pipeline. Supports sphere and plane primitives, with other primitives coming soon (including triangles, and hence meshes) Point lights, with other light types coming soon.
XNA – A Simple 2D Camera | roundcrisis.Find<Solution>()
https://roundcrisis.wordpress.com/2012/04/19/xna-a-simple-2d-camera/
In 2D, to perform a rotation, we always rotate around Z. Then we need to scale, using the parameters that we sent on update. Don’t forget we set different levels of zoom in each of the two cameras. We use the overload of Matrix.CreateScale () that takes a Vector3 to create a …

XNA 2D Independent Resolution Rendering - David Amador
https://www.david-amador.com/2010/03/xna-2d-independent-resolution-rendering/
It’s your working Resolution. The other one is the resolution at which the game is rendering, which we want to be independent of the game. So the class will scale your Virtual to the Actual, making a LetterBox or a PillarBox to match them. Resolution.SetVirtualResolution(1280, 720); Resolution.SetResolution(800, 600, false);

Here's what it looks like when I stop at the root bounds, without using the DDA to traverse the tree: /* find which leaf, if any, the ray intersects. Returns transparency (Color (0,0,0,0)) if no intersection was found. TestValue is a shader constant parameter passed from the caller which is used to dynamically adjust the number of loops the ...
