Graph3DP v1.0 Beta 1; Prizm Hacking Continues

At the graph screen of a calculator such as a TI-84+, the free-moving cursor can be moved with the arrow keys, in any direction. Of course, in Graph3DP, you'd have to implement in 3 dimensions. Perhaps you can use +/- as well? Also, are you planning support for multiple graphs?

You haven't read through my posts, even the ones from yesterday, at all, have you? Razz

It already supports arbitrary simultaneous graphs, although for memory and speed concerns, that is already capped at 6. Regarding the free-moving cursor, I can't say that I really see the point for a 3D grapher. I think it would mostly be confusing.

Wow, lots of updates. Can't wait for a release so I can play around with it more—I've unfortunately been underusing my Casio Prizm :/

And I agree about the free-moving cursor. It would be confusing if only implemented for two dimensions, hard to control if implemented for three, and IMO not terribly useful. I don't think I've actually used TI's graph cursor outside of trace mode for anything related to math at all.

Thanks, glad to hear you agree. I am wrestling with the issue of proper rotation, re-writing it from scratch, and might end up just deriving out the equations myself. As soon as I get that working, and add more help, I will release another beta.

*bump* I implemented MCS-based state-saving so that you can interrupt the add-in, go back after running other add-ins, and your window and equations will be properly saved. I also added an hourglass that gets displayed when complex equations are being calculated, and re-formulated the camera-position calculation from XYZ Euler angles and the camera transform from the same Euler angles. I need to add proper frustrum culling, and am still wrestling with rotating the camera properly. More information on that latter here, particularly if you have any brainstorms.

Kerm, I want to graph a 3D heart, but to do that, I need to do an equation of the format (X)(Y)(Z)=A. I know you're busy though, so I'll let you do what you're doing!

I had proper arbitrary rotation around any axis, but it was from a fixed rather than dynamic point of view, which I don't think people would find as natural. I am determined to figure out the proper way to do what I am trying to do. Smile
