How do I project lines onto a canvas at runtime?
For starters, I asked this question a few years back for a game dev project, and never got a satisfactory answer. THe project got shelved and I moved on. Now I am working on a trig and calc visualizer as a dual project to teach my son programming and my daughter how to visualize trig and calc functions.
What I am trying to achieve is as follows:
-Create a 3d object with editable parameters to define its movement. -Raycast from the tip of the object onto a object/canvas/etc -Render the trail where the raycast collides with the object. -Be able to reset the graphic between tests.
The first two I can manage, including getting the hit returns and locations. Being able to reset when the test ends is easy enough. It's that third bit that is giving me fits.
