My current status:
I have already read some tutorials about 3d collision
I know how ray trace works and how to convert mouse follow a vector to track the closest object that collides with out vector I have also worked with 2d collisions before and I've seen some collision samples from "apphub".
My problem is mainly because all the tutorials I have read are about collisions over 3d models on .fbx format but I don't use model files... I use simple primitives... So what methods do I need to check to be able to know if a 2d sprite has collided with my 3d isometric triangle? Also bounding box will have blank spaces outside my triangle borders that will return a false positive.
Is there a way to transform primitive into 3d models so i can use Ray.Intersect?
Do I need to transform the vertices into 2d points and then check if any pixel from sprite is between these 3 lines?
I'm also aware of boundingbox but it doesnt seems to be a good solution since we are talking about a triangle not a square. Or should I create a bounding box around the 2d sprite and then try to collide over all the Z's?
If you need clarification please let me know. I'm not very good in explaining myself.
